Saturn Vue Throttle and accelerator issues diagnosis

[@julianfell666]

I have a 2003 Vue manual 2.2L. When I first acquired it, it went to limp mode constantly. It was particularly bad in wet weather. This can be cancelled by turning the engine off and then restarting. One nice thing about the manual is that the engine can be turned off and restarted without pulling off the highway. Just disengage the clutch, turned the key off, turn the the key back to the run position, lift your foot off the clutch pedal slowly and let the movement of the car restart the engine. The DTCs were P1271 and P1275 which indicated a faulty accelerater pedal position sensor (APP). So I swapped in a new one and nothing changed. I traced the wires and found that at the main connector block (to the left of the drivers left leg) the 6 wires involved had been bypassed. The party I bought the vue from had no mechanical expertise. So it seems others before this owner had been dealing with this problem for some time. I had another Vue so I swapped out the PCM. the throttle body, the manifold absolute pressure unit.......all of which had no effect. I cleaned the throttle body and this made an improvement. I used a scanner to track the freeze frame data and it showed no trends. I had concluded at this stage that the problem was in the wiring rather than the modules. I tested all the wires involved and they all showed resistances in the correct range. I opened up the back of the J1 connector on the PCM and found it full of dust and crud. I washed this out with Carb cleaner, toothbrush and q-tip.. This seemed to make quite a difference. I watched a video by Ivan at Pine Hollow (actually I watch a lot of his stuff) where he mentioned that electronic sensors tend to operate based on voltage rather than current. This makes them very sensitive to moisture, oil and dirt which can ground out voltages. I cannot say I have fixed the issue but I dont get limp mode any more in the summer. The codes shown in this video for APP problems are for the 2002-2003 Opel V6, which differ from those of the 4 cylinder ecotec.

Awesome video, appreciate how in depth you explain the issues and codes.

[@nathanskeeter2562]

Is there an update to if this fixed it?

[@susantercek8339]

We replaced the pedal and the car is still acting up. We've replaced several parts and still can't figure out the problem. Very intermittent glitch. Car bogs down when starting out or shifting down. I'll pull off the side of the road to a complete stop, car will shake and sometimes the check engine light will blink. I'll turn the car off and turn it back on and it clears the issue. Any thoughts? 2004 Vue 5 speed 4cyl.

[@Kasontiktok]

Reduce power light ???

[@rudysanchez9823]

Hey have you come across a engine noise under valve cover on a 2007 vue v6

[@TylerZachary0]

What did you figure out? I'm having the same issues, I changed the pedal. It didn't work. I have u2105 and p1779 codes come up. The interior lights sort of flicker like a drain is happening, even after I noticed that I put in an after market radio. First time doing it, could this be the cause? Had a test ran on it at advance, Alternator is great, new battery, but says the starter gets ZERO volts but it runs and starts fine? I've checked the ground is fine all over the car. Before I cleared the codes these were the codes U1016, U2105, P1779, P0703, P0504, 02135, P0221, P0700. It didn't start doing this until I changed the brake booster and master cylinder and rotors and brakes but that doesn't seem related.

[@lasaventurasdelchinoychini3516]

Did you find the problem? I have the same issue I'll appreciate your respond. Thanks in advance!

[@elooforlando]

Q: I got a 05 ion 2.2 w/ the same problem. I changed the throttle, pedal, coil pack, ignition module, knock sensor and crank sensor and still got the same power down problem. Besides a match and gas , any other info to fix this problem?

[@BrodyHarris]

Yeah, does it jolt before losing power? Almost like the throttle body gets stuck completely open for a split second before slamming shut?

[@69in89]

I'm considering buying a 2003 Vue with the 3.0 w/ 112K on the clock for a good price. Am I better off just replacing the accelerator pedal, BCM, and TCM for preventive maintenance? Planning to put a lot of miles on it.

[@TheMrmmkkpro]

I have a 2005 ion, no crank, no start, good starter, good battery, all fuses and relays good, no problem with theft system. Any thoughts? It's like whatever is suppose to tell the engine to start is not working, no crank and no power to fuel pump. Nice video, thanks for the Info. 👍👍🏁🏁

[@ceezauto213]

Hi great video. Where can find the vehicle speed sensor on this car? (P0500 code)

[@hilfiger.__hendrix._2181]

Had some of the same codes and tried everything as well new throttle body an all if i shut it off and then when I started it it wouldn't accelerate could that b tcm?

[@jdotjohndoe7110]

I have the same 03 Saturn vue - Code p0700 & U2105 shows . Mines glitch out as well , what is the best solution for me to fix this problem

[@e.rivera4251]

i had the same issue...was a clogged catalytic converter and the sensor at the intake. On the minivan ( i had 3 ) must replace the harness wiring a must and the computer can be send for a re-manufactured and programming it cost me $700.00 total.

[@stephaniesutton6715]

i have a few questions???? my 2003 staurn vue is throwing the sercurity light and i cant figure it out is there anyway you can contact me threw a message or something i have changed the throttle body and pedal and knock sensor and nothing has helped

@@MattShaughnessy6 could it be one of the o2 sensors??

[@ianclifford3556]

How do I replace the tps?

[@BeckleyAdvent]

I have a 2002 3.0 Vue. My problem is after a engine swap, my shift points are much higher causing higher fuel usage. What would you suggest I do? Thanks.

[@BlindmanVlad]

It’s the engine that is using more gas, shift points are from the transmission.

[@valerierumfelt953]

Mine chugs when u excelerate rpms run high in 5th gear. Changed the catalatic converter cuz that is what the code said it was. Still having the same issue. It chugs accelerating and them it jus takes off. Help!!!

[@mikecamps7226]

has replacing the gas pedal assembly solved the problem ? I have a 2003 L300 v6 with a similar problem....where the wrench light comes on and then it drives "better"....but it acts as if its running lean with no power in the rpm band where the 2 to 3 shift is so 25 to 35 mph is the worst speed for around town driving. Seemed to me as if it was an old school computer TPS situation if it were a mid 1980's car …...not the OBD 2 system that it is. But in either case....replacing with a new gas pedal assembly or a new throttle body is expensive. THIS IS WHY I PREFER NON COMPUTERIZED CARS AND TRUCKS......give me old school HEI distributors and carburetors

[@cjcreel4500]

Had this problem on 2002. Replaced throttle body and excelerator petal. $1600 new parts, went to pull-a-part and took off parts...simple. $56. Problem solved and I'm not a mechanic.

[@cjcreel4500]

Oh yeah, cleaned the carbon buildup off throttle body before installing.

[@trinidadbreeze]

basically it narrows down to pedal or throttle body if it goes slow and no acceleration change pedal and or throttle body diagnostic tool unit takes out the guessing.

[@BrodyHarris]

Auto Surgeon51 Not true, I just fixed both of those on mine and it still craps itself periodically. Not every single time, but I daily drive it with this problem always at the back of my mind and it could happen at any moment...

[@peterroberts4555]

Great work

[@arielgonzalez6926]

Tengo una 2003 saturn vue y se para cuando anda jalando y prende el reduce power que sera por favor? Gracias

[@adamclark4292]

Good video really helpful 👍

[@Tsukuyom1t]

Im having a issue with acceleration when I first turn on my Saturn Vue. Its slow/sluggish and then after a couple seconds its just fine.

[@heatherprater6273]

It's crazy that my 2004 Saturn Vue has all of the same exact problems. So I need a new body control module and I should replace the sensor on the ignition. I've been dealing with these problems for 3 years.

[@heatherprater6273]

My power steering stops working when my gauges don't work

[@slim150a4]

I had the same issue at my 2002 Saturn vue 3.0l v6 and I turned out that it was the throttle body

[@jessicacherelle3595]

I have an 2003 saturn Vue and it always says reduced power and people are telling me that they think it’s the catalytic converter

[@moosepilot3145]

2007 Vue idles rough . Please help

[@mrlbjunk]

Put it in neutral and see if that helps. If it does that means you have a bad motor mount.

[@kylesmith626]

Lucius gas cleaner the big bottle drive the gas to E pure half of bottle of gas cleaner than put gas in your car it will still idle high at first but will eventually calm down I also have a 2007 Saturn Vue

[@cassandraireland3352]

What city are you in? Can I bring you my vehicle

[@MattShaughnessy6]

Boise idaho. yes you can in you live here

[@chuckmusic09]

Body control module need to be flashed

[@firestormgirl1962]

That's what is happening to me on my 2004

[@MiguelMartinez-hm1hg]

What can you said about the Zurich code reader

[@MattShaughnessy6]

love it! it has made my diagnosis on 1995 and newer way easier! since this is what I do to feed the family i need something that will make me money. this one has paid for itself many times.

[@MiguelMartinez-hm1hg]

Thanks for reply an taking time to answer I really appreciate have you seen the new Zurich scanner looks more like the Mixidas from autel

[@CHICAGOSTYLE312]

Did the pedal fix the issue?

[@sandygennarini268]

My car is doing the exact same thing I have an 03 Saturn Vue did the pedal end up fixing the problem
