PNP Park neutral position switch replacement cleaning. Error code P0705, Volvo 850, S70, etc. - VOTD

PNP Switch: 60 to 90 minutes ($95 / $290 / $400)
WARNING: When you unplug this PNP switch, the car will NO LONGER know that it is in PARK and MAY ROLL AWAY from you. THIS CAN CAUSE SERIOUS EQUIPMENT DAMAGE, BODILY HARM AND POSSIBLY DEATH to anyone in the path of a run away car. Make sure that the vehicle does NOT roll away.
Temp fix and other information: • PNP switch information...
A bad PNP switch can cause a NO CRANK issue. It will also cause your transmission selector switch to flash lights as well as the arrow on the cluster. In this video I replaced the PNP switch on a '95 850 turbo.

[@chrisplewis1976]

My reverse lights had stopped working and bulbs were OK so next stop was here at the PNP switch. I was able to service the PNP whilst it was still connected... i.e. I didn't take the gearbox socket apart ( I tried and failed!) I had already obtained 3 C shaped pieces of copper as a kit (from ebay) which slide around to make contact at various positions. It was just a matter of taking the screws out, and pulling the switch apart and carefully replacing the copper parts. Clean and grease and reassemble. Lights now working woohoo! Thanks again Robert for a really useful video!

[@sabinetrupp8659]

Robert DIY Well, more or less, the Volvo goes maximum 200 km/h ;-) We have one more question: it seems, that the Volvo did not notice completely, that he got the new switch. We have reversing light, the arrow is off, but sometimes it feels, as if he is not in a gear at all. Do you know, if we should do a reset of the TCM? We were thinking about disconnecting the battery overnight? Best regards, Sabine and Daniel

[@RobertDIY]

Transmission may be going out. Have you changed the fluid? - kzbin.info/www/bejne/oaqwZI1jh7ypmdk

[@sabinetrupp8659]

Robert DIY Yes, this was the first thing we did. We changed the fluid twice. Then we changed the pnp switch. Then it was better, but not really good (as described above). Now we had the battery disconnected overnight. And now we will make a longer test drive. See you later.

[@RobertDIY]

OK, hope it works out for you. When I purchased my car the trans was already bad.

[@repairsrevampsrenovations2890]

Hi Robert. I'm from the UK and have been researching a no crank no start issue on my 1995 850 GLE T-5 Estate (or station wagon, if you prefer), the Volvo designation being 855 Turbo. Battery is good, fuel pump is good, fuel in the tank, but no crank. I suffered the flashing gearbox/transmission warning light a couple of days ago, and did a little research and did the quick fix of running the gear selector through all positions several times, and this cured the problem, only no I have a no crank no start issue, and no click from the starter solenoid, making me think there's a problem with the gearbox, which is what led me to you and your videos. I haven't tried tapping the starter solenoid to see if it simply that which has jammed, but that will be my first port of call. My partner tried to start the car with the auto 'box in D a couple of days ago, and the symptoms were similar, but she changed to P and it fired right up with no apparent issues. While I have been researching this problem, I have seen on a couple of forums that it could also be the ignition switch, which I really don't want to tackle, I'm more mechanical than electrical. I can say though that I will be trying to either replace or refurbish my PNP switch having just watched this video, I've watched a couple and they're really informative! If you have any further advice, please reply to this, I'd be grateful to hear it. Thanks! Chris

[@RobertDIY]

Chris Long PNP switch or starter. I'd roll the shifter a few times and if that doesn't work, remove the starter for testing.

[@angiehurtado8060]

Robert, these videos have been my starting point for any problem with my '97 850. You are the man, thank you so much. With that said, I was hoping you might offer your opinion as to where you would start to resolve a new problem I have. I know my way around most cars but given that problems, especially electrical, can manifest themselves in a variety of ways l thought I might try you first before I start replacing parts. Problem: cursing at 40-50 mph it slips out of gear and into neutral (I assume) when you stop the car (running fine) shift to park and back to drive, nothing. Turn the key off, in park, restart the car and it shifts normally. Thoughts on where I might start looking. Thanks

Is there anything else to consider before I go in and change pnp swich?

Robert, you are awesome! Very kind of you to post this kind of information. By the way, for the first time, my 1992 Volvo 960 is starting to flash the orange up arrow on my instrument cluster. Any idea where the PNP switch is located on the 1992 volvo 960? I'm guessing somewhere on the transmission. On this car things are arranged differently than front wheel drive volvos being a rear-wheel drive car. I did try turning the key to position 2 and moved the shifter from park all the way to low for 20 times. That worked for about a day but now problem came back. Also, the reverse lights do come on when the shifter goes to the reverse position.

[@soundgal_sine_qua_non]

Ok. I replaced my pnp switch a few months ago because the car was continuously falling into limp mode. Since replacing it, it doesn't do it anymore, but every so often when the car is either hard braking, braked at a stop light for a long time, or left parked and on for an extended time (I was trying to unlock my radio), the engine just dies. I turn it off and back on again and it works, but it's an odd intermittent problem. Any ideas as to what it could be?

[@steverahe]

Hi Robert-have you ever overhauled a PNP switch with 3 new copper contacts (you call them "pins" in your video)? Theres a kit available for like $20. The advantage I can see is that it can be done while still in the car - so no need to take apart and put together the electrical switchblock. the disadvantage is that you are working on the little pieces inside your engine. What do you think of this way? Also, a lot of the write-ups on how to do this talk about an alignment tool and how aligning it properly is critical. DId I miss that step in the video or did you just eyeball it? Thanks!

+Robert DIY - Yeah, and my back doesn't like leaning in like that for long...but I think I'm going to give the kit a try. That way I get the "worn" part replaced but I still have the genuine VOLVO PNP without paying $189. I'll let you know. Part is from SwedishCarParts dot com

[@RobertDIY]

Is that the same company that sells the heater core?

[@pochosito]

It is a 95 volvo 850 turbo. I replaced the Pnp with a Chinese version and I guess it broke, put in a used oem one. Now I have a different problem. The car won't move at all on drive gear,3,L or reverse. There is a noise coming from the transmission. transmission fruil is good. The oem P np switch came out of a newer volvo. I think a 2004. can that be the problem? how can I know if my transmission is not broken?

[@RobertDIY]

+Andres Cardenas Those parts are very different. Get the proper part. Check the part on a parts website and see which ones will work. Likely from '94 - '99.

[@jamesmoss2540]

I have a arrow light that comes on right after I turn the key over then it stay on for like one second then cuts off but my car switches gears smooth and some people say that it's a transmission issue if it starts flashing but could it be the pnp switch? There's no check engine light either and the dealership said that the 850s show that light often what do you think I should do should I replace the switch ?

[@RobertDIY]

Jamea Moss If it goes off within a few seconds, why worry about it?

[@jamesmoss2540]

Yeah it wasn't the transmission or pnp I guess it had something to do with the something in the timing kit because I had that replaced last week just because it had t been changed yet and it hasn't came back on since thanks @Robert DIY

[@nowherecentralnetwork8155]

Hey Robert, my 1999 V70 XC won’t move or rollback in reverse and neutral. The car does however roll forward in neutral and drives forward in drive. Could the PNP switch be causing this? The reverse lights do turn on when reverse is selected in the gear shifter

[@RobertDIY]

probably bad parking brakes.

[@nowherecentralnetwork8155]

Thanks Robert, I’ll start there and see what I find

[@billyopotato]

Hey Robert would a bad pnp switch cause a crank no start on these volvos ive been having a intermintant crank no start issue that always shows up with a flashing transmission arrrow im wondering if i replace or clean my pnp switch if my car will stop having intermintant crank no start problems or if i should be looking at other components ive watched alot of your videos i have good crank and cam sensors have fuel at my rails and spark at my plugs what else cause these cars to cranks and no start im really stuck here any help would be appreciated

[@RobertDIY]

I don't think so. Usually a no crank issue.

Hi Robert I have followed this video, but I have hit a problem with removing the 3-part electrical connection. I have tried various thin blades to depress the clip at the en, but the connections wont shift. I think I have damaged the clip. Is it possible to disconnect the other sets of wires from the top of the gbax & remove the whole lot? Great videos by the way.

[@RobertDIY]

No sir, you need to get that to separate.

[@stevecarter4129]

@@RobertDIY Thanks Robert. I will have to do it in the engine bay & be very careful!!

[@LordJones-mw6is]

I just (about) have my t5 back together after doing this, but when I go to put it in neutral, the gear shift won't move, even when I push the little release to the right of the gear selector. I'm at a loss

[@RobertDIY]

It's stuck in park?

[@user-tc9ms6sc8l]

Hi Robert I appreciate all your post here. I have a 97 850R and it has a problem I can’t figure out the cause. I hope maybe you might have some idea how to fix it. When I put it in reverse it just barely moves. I checked the fluid and it was fine level. There are no codes for the transmission. It drives fine and all forward gears. I’m wondering if it could be a solenoid? I’ve also had the same issue on my 89, 740 turbo. Please let me know if you have any ideas. Thank you.

[@RobertDIY]

I would check the parking break

[@user-tc9ms6sc8l]

I am sorry I don’t understand. Can you explain? The parking brake is completely disengaged. The car rolls freely forward and backwards. The issue is when put in reverse. It doesn’t engage solid. It’s like it’s slightly connected and on completely level ground. It will move a little bit. I was hoping that this might be a solenoid or something simple I can replace, someone told me that when reverse goes out, it means your pump in the transmission is beginning to fail. What I don’t understand is the car drives perfect and I’ll forward gears. Have you ever encountered this issue with the 850 Volvo before on the transmission?

[@dgoldman2846]

Robert, PLEASE REMEMBER to mention that you need to remove the damned TIE WRAPS before pulling on the pins and that the easier way is to push the tab and grab the harness and pull and it should come out.

[@RobertDIY]

+D GOldman Thanks for watching and sharing.

[@OlliOvaskainen]

Hi Robert! I replaced PNP switch and now I still get error 313, if I switch to P(park) or L(low). I can start car, park and neutral position and reverse light is on if I switch R position. TCU is also replaced. The problem occurred when I flush my transmission oil. Oil level is also checked. Transmission works if I don't use P or L. Any ideas what is wrong?

[@RobertDIY]

Sounds like something is wrong/bad in the transmission.

[@OlliOvaskainen]

@@RobertDIY New PNP sensor was faulty.. Next time I buy original Volvo parts only!!

[@traintalkers]

Hello Robert! I was driving home from a long trip when I suddenly got a flashing arrow and a check engine light. When I got home and read the codes and I had a p1618 and a p0740. Could this be my pnp or my solenoids? Thanks

[@RobertDIY]

I don't know, maybe a transmission problem. Is it idling smooth?

[@RobertDIY]

I don't even know what kind of car you have.

[@traintalkers]

Robert DIY I have a 99 v70 glt I found out my trans was low and leaking out and I couldn't engage gears. My axle seal blew out after I put in new axles so I'm hoping my trans isn't fried

[@RobertDIY]

Ok, hope it works out for you.

[@Pveedot]

I have a 94 850 Turbo sedan that does not shift passed 2nd in the morning. Once it is parked, it will not start for 20-30 minutes but when it does there are no problems. It runs well and shifts perfectly for the rest of the day. It can sit for 8-10 hours on the same day and still start just fine. But, every morning it will do the same thing again. I'm wondering if the PNP could be going out and that is the problem?

[@RobertDIY]

I doubt it.

[@RobertDIY]

kzbin.info/www/bejne/mJfImo2una-arrs

[@Pveedot]

It doesn't throw any codes on it.

[@RobertDIY]

Still need to check.

[@ChristopherTrimble]

Hi Robert! My arrow just started flashing yesterday. It seems to shift ok but sometimes it seems to drag in 1st gear. I also checked the transmission fluid when it was cold, I pulled the dipstick out, wiped it off and put it back in then removed it but the transmission dipstick seems to have transmission fluid above the cold line, the same thing after I checked it when the transmission was properly warmed up. My car will start and drive in first gear not 3rd. If that helps. I also have noticed that the W button will not press down like the S and E button for the transmission. Do you have any insights to what is going on with my issue? Thank you for your time.,

[@RobertDIY]

First off, pulling that dip stick out in any other situation other than what the manual recommends is a waste of time and will give you bad info. Other than that, you need to get the codes read. What condition is the fluid in? The W can only be engaged when you are at a full stop.

Hi Robert! I got 3 codes: P0123, P0120 & P0108. The W button will not engage in the on position when the car is fully stopped. I ordered my PNP switch today.

Hey whats cuse tranmison sliping a jearkin 2001 v70 2.4 turbo

[@RobertDIY]

probably needs a software update.

[@dynamo057]

I am having problems with a check engine light after running through these steps. I don't think I have the switch aligned correctly but I do have reverse lights. The coffee comes up as 'prndl'

[@RobertDIY]

What is the code?

[@dynamo057]

Robert DIY I believe it was P0705. I failed my DEQ emissions because of that also :/

[@RobertDIY]

Probably a bad switch or transmission problem.

[@dynamo057]

If the switch is good, is there anything else I can try. I am asking because I have replaced the pnp with multiple units from the junkyard and the current one is rebuilt... Thanks again fro your advice

[@lynxwomancat]

1997 850 Volvo Sedan won't go in reverse, only forward. Will the pnp switch effect the reverse not engaging?

[@RobertDIY]

Sandy Crowley I doubt it. When I got my car it would go into reverse and first at the same time. Reverse for about a second, then first would kick in and they would fight each other and first would win.

[@lynxwomancat]

A guy at work is selling his Volvo 850 (1997) for $500 here is what he says is wrong with it. Biggest issue is that it doesn't go in reverse. In Reverse, it goes forward. In Neutral, it goes forward. If you leave it in gear and turn the car off, it can roll backwards, so it's pretty inconvenient. However, it runs good and drives forward perfectly well. I've researched it and it looks like the PMP switch is bad, which from what I can tell can be fixed without taking it to a body shop. BTW, I really enjoy your videos, very instructive. I'm not afraid to tackle any mechanical tasks with clear instructions :-)

[@RobertDIY]

Ok, have you watched the Pre-Purchase video? One of my friends drove his 850 125,000 miles with no reverse.

[@lynxwomancat]

Wow, yes, I found your video very informative. Thanks so much

[@fadedjayy]

This should work on my 2000 s40 as well, correct?

[@RobertDIY]

Jordan Chavez I believe so. Roll the shifter through all gear settings a bunch of times to see if that clears your problem up temporarily.

what is the big deal with adjustment? I am guessing the slotted holes in the switch housing is where the adjustment would be?

+j83460 what I show is what I do.

[@j83460]

I guess some people make more of it than is needed, thanks Robert for your help

[@RobertDIY]

They really do. Do know that the car will pop out of park when the connection is unplugged. If not on a level ground, IT WILL ROLL AWAY.

[@FeraNenem77]

Hey Robert, how goes it? I was having a no start no crank condition. New battery and new starter. Had no flashing arrow and no check engine light. Replaced the the pnp switch and car won’t go passed 3rd gear and now I have flashing arrow and check engine light. Please shed some light. Thanks P.s. I completely forgot to put parking brakes and when taking old pnp switch out car rolled a little bit.

[@RobertDIY]

Yikes! People like to ignore that warning. Where did you get the PNP switch?

[@FeraNenem77]

Robert DIY got it from Amazon. I ordered another one, brand is URO. As soon as the rain stops I’ll change it out. By the car rolling will it cause problems? Hopefully when I change it again it will work. If not I’m screwed.
