Code P0123 TP sensor Circuit High?!?!?!
 
AND P0146 or 1406, I didnt have pen and paper at the time . It is the EGR Printle Position. Anyone have any idea what this(these) might be from experience :?: As soon as i start the car its fine until i hit the gas a couple times. then the check engine light comes on and my car goes crippled. Its at the dealer now, at least i got a grand prix loaner this time. :roll: He tried to manually override the EGR printle psoition and went from 0% to 100% and nothing cahnged, he said teh car should have died from doing that. SO, probably a new EGR valve$$$ But what about the P0123?
It seems everytime i do something good, something else breaks. Ran perfect for 5 years up until i started moddding 3 months ago. :cry: Theres been a ratio of about 2000 to 1000. Spend about 2 grand on upgrades and 1000 to fix things that break as a result. Uh well, to bee expected with 117k miles. Everything will be new again at this rate. :woowoo: thing that really bites is my wheels and tires are coming in tomorrow and the cars in the shop. :cry:

I suppose its possible for the EGR problem to cause the problem with your TPS giving a high voltage. I would get the EGR repaired first, then check to see if the code comes back. If it does then it could very well be a bad TPS.

You can test the TPS... The voltage should range from around below 1 volt at idle to around 5 volts at wide open throttle. You don't have to have the engine on to test it.

hmmmmm, thats a tough choice. The EGR is A LOT more then a new TP sensor!
I was watching as he checked the voltage of the TP sensor at idle and it was around 1.2 volts and should have been around .4volts. I dug up a lot of dirt last night on these horizontal EGR valves and apparently the pintle sticking is a common issue. Cleaning it sometimes helps. What im worried about is it seems like its not moving at all, not just lagging behind is a millesecond value.

IT all spells MO Money Mo Money Mo Money when you dont have time to do any troublehooting and its the daily driver. :cry:

I am seriously considering buying the EASE SCan tool for 350 bucks. I could really use one being that i have to drive so damn far to get to the dealership. I work in the city and they arent as kind as they are in the country! :) I called a garage yesterday to see if i could bring my car over just to have the code read to me while i was at work. The said sure! It'll cost you 75 bucks tho. I couldnt help laughing BEFORE i hung up. The dealership does it for free.

WELLLL, got the car back from the dealership, needed a new TP sensor AND EGR Valve. 471.00 total. :( ON the brighter side, I took my car straight to Mr Tires where my new wheels and tires had been sitting for 2 days and got them put on. All i can say is SCHWEEETTTTTTTTTT!!!! (Hopefully i'll have picutres on car domain by tonight or tomorrow night.)

i had that high voltage 4 volt thing happen to my car in all i replaced a computer,tps,o2,fuel filter,cat(soon) my biggest problem was when i gave it gas nothing happen i had to have it floored just to move which causes me to over heat

Nytro67 05-30-2003 11:26 AM

OUCH! SOunds like i got off light then! :roll:

Nytro67, how is your car running so far? Any occurances of 1640 EGR Pintle Postion code? I'm having the same problem in my 95 bonnie, I'm just wondering if getting a new EGR valve solved your problem? I've already cleaned my EGR valve but that didnt solve my problem.

Nytro67 06-01-2003 05:16 PM

Its running much better now. no more 1406. It solved my problem but anything that cost that much better solve it!! :lol:
