How to diagnose and repair a P1105 and P0105

How to diagnose and repair a P1105 and P0105 on a 1999 Nissan Maxima In this video I will show you how to diagnose and repair a P1105 ( MAP/BARO switch solenoid )and a P0105 (absolute pressure sensor) using just a vacume pump and a multi meter

[@AnilPasram]

For anyone wondering the map/baro switch is called the Vacuum Switch Vapor Canister Purge Solenoid Valve. For my 99 Maxima it’s part #14956-35U10. Hope this helps!

Good to see you emphasise the importance of "testing not guessing" and proving your diagnosis with the bench testing of components Jim. Many shade tree mechanics would replace parts unnecessarily based on DTC's. I really enjoy your electrical diagnostic videos - hopefully there will be more on the way!

[@txsviking]

That was great. Getting to see the new one working the way it should. 👍👍

[@Krillekris]

Great and simple diagnostic!

[@fieldsofomagh]

Very handy procedure to know and remember.

[@dylankinch2735]

hey jim love your vids buddy. im in utica ny we are getting slammed with snow right now as i believe u are as well. have a good day my friend

[@haywardsautomotive6156]

Nice diagnosis & repair Jim.

[@kingsleyevru5239]

Great Video. Thanks for the explanation

[@stuzman52]

Great work Jim!

[@midi510]

I can only imagine what it would be like to be able to get a part the same day you order it.

[@baxrok2.]

Good job!

Great vid. I have a question, why is there so many different names for the MAP sensor? IAT being one of them. Also I have code P1105 on my R56 mini but I don’t have this turbo solenoid as my mini isn’t turbocharged. I’ve just replaced the ‘MAP’ sensor (IAT) but didn’t do the tests you did, hopefully this fixes it. Thanks for your vid

Great Video How about a p0500 on a 99 pathfinder? Replaced VSS reset CE and came back on after 2trips. I don't have a wiring diagram and really hate to guess around. Thank you

[@everardocamacho5063]

Jim,I have watched the video couple time trying to understand the procedure, im little confused, you check for 5 volts reference then you back probe the connector with a pin, my question is ,you back probe in the wire that has the 5 volts references? My other question is ,on the baro/solenoid the polarity for the outers pins it matters ? I hope i make me understand better this time, thank you jim you are my hero, take care,

[@jimthecarguy]

Thanks for watching.

[@juvenalalvarez9535]

another great great video. what is feeding that solenoid, what is for that solenoid.

[@dezblyan5125]

Good job jim

[@re4thee]

Problem I have might be wrong hoses fixed where they shouldn't be. I cant find a video that traces the different hoses to know if it is on the right port

[@everardocamacho5063]

Hi jim good testing method, just one question on the solenoid test ,the polarity does not matters, it will click both ways? Thank you and take care yourself and your family, un saludo desde Ontario California

[@jimthecarguy]

Thanks for watching

[@stanskubis7864]

Hi Jim, Could you do an ohm meter check of the coil as a double check of the solenoid for those that do not have a power probe

[@reweydewy]

Stan Skubis It's not a great test. you can ohm test but if the solenoid windings are good but and the valve is mechanicaly stuck you will still get a good ohm reading. You can always take long wires right off the cars battery. best to use a fused wire for one of the wires.. that's basically all this older power probe is doing

[@stanskubis7864]

reweydewy thanks for the helpful info. Will remember next time I come across it

[@rakhmanbinsakwar470]

Thanks for the video Jim! Question: I don't have access to a vacuum pump, but I'm assuming that the signal voltage should get lower as I apply throttle?

[@jimthecarguy]

Thanks for watching.

[@jerrylinder2977]

Voltage should drop when applying vacuum pressure. Release the pressure and the voltage should return to normal. Hope that helps

[@OneAuto]

Nice Job Jim. Did you make into work in the snow? its been all over the news over here!

[@SwaiyeTV]

Where can I get the solenoid? Can't even find it online

[@jaysonsvisions5024]

Quick question, I have a P0105 code only and it says it's the MAP sensor. I replaced it cleared the code but it came back on. Should I try the solenoid next? I tested all the power and the vacuum line is OK. Thanks for any help. It's on this car as well

[@youtubescrap]

Did you test the solenoid and was that the fault I have the p0105 on my astra ivereplacedit and cleared the fault but still engine management light is on

[@jaysonsvisions5024]

@@youtubescrap bro I never got it fixed. The shop wanted $1000 to fix it. They said it's safe to drive so I did then sold it.

[@matthewwach7693]

How would you know if you got the vacuum lines mixed up?

[@jjahib6253]

Use soap and water

[@baddriversofnorthtexas6850]

hopefully eric O will get up to level Jim someday (sorry eric if ur reading this dont hurt me)

[@kennynvake4hve584]

you dont hear the solinoid clicking, I do at 8:24

[@slonon6410]

how do i test the ecm ground to the solenoid?

[@jimthecarguy]

Thanks for watching.

[@alfredopacheco9415]

Jim were r u located at?

[@hitmen2025]

Opel corsa c 1.7 dti. Am having p1105 what can i do thanks my8

[@javirojas3017]

Good .

[@bossslapahoe]

Hi Jim, you've probably been asked this 100 times, could you tell me which shop light you're using?

[@jimthecarguy]

Yes I use mostly florescent lights and I also use the OTC Spectrum lights

[@Demonzav]

Man I've look everywhere for this solenoid for the code p1105 I have the map but Noone can't get baro lol

[@stephenvoit8648]

Can you give me the part number for solinoid switch

[@alfredopacheco9415]

We're is ur shop location? "

[@TheMinorCatastrophes]

Do you happen to know the part #

[@jimthecarguy]

TheMinorCatastrophes Every parts store has a different number, check with your local parts store.
