TPS code '99 sus

[1-3-2-4]

The code is p0122 about the tps circuit.. Long story short a friend had another do some work and got a code for the sensor and the car shakes bad.. So looking at it I see he adjusted the TPS and stop screw.. I'm having a hard time getting it to idle normal and not try and idle at 1500.. When the cell for the TPS comes on car is really really down on power.

 

So now I took measurements from my onw can and saw the stop screw was really off as in the top bar was resting on the throttle body when closed..

 

My voltages when at idle are .48v and 4.56v WOT

 

haven't tested yet after mirroring my cars settings.

I should of said I check the sensor to ground and I got something like 5.1v and signal to ground and that was fine

 

Mirrored my car settings and as soon as I started the car the idle went between 1000 and 2500 over and over

Well OK that code is gone but I have two new codes...

 

P0507 and p1507

 

The car is a automatic so could the inhibitor switch be bad?

Did you re-adjust the throttle stop screw?

It's tricky to get it right and will throw off idle speed if not set properly.

I set it so it mirrors my own working car..

 

The only codes now I'm left with is P0507 and p1507

 

I'm about this close to throwing my hands up and getting a throttle body from the yard and replacing it..

 

Too much crazy stuff was messed with this car... Mind you this women has really bad brakes.. I told her about it (whole wheel shakes when putting on brakes) and a huge amount of air in the lines.. to the point if you press the pedal to the floor it's like lightly pressing the brakes on a working system..

 

Told her and she said..

 

I know! It's OK I don't drive fast....

 

next thing I know it will be metal on metal or metal to brake fins..

Both idle control codes.

The idle air control valve could be at its limit due to incorrect throttle plate opening.

 

Clean the throttle bore and plate, back the stop screw all the way off, then work the throttle lever a couple times.

Turn the stop screw in until it just touches the throttle lever.

Adjust the TPS so it reads about 0.50-0.55v.

Reset the ECU.

Heres the spoob that happened yesterday.. I got a harassing phone call from this guy about the car and I told him I'm going behind someone else who fucked the car up.. they adjusted the stop screw, IAC and TPS.. I said keep it up and the cops will be glad to visit you.. so he slowed his tune down saying he was sorry..

 

So he ended up screwing up the car again.. he threw the TPS out of wack again so the point where the 4EAT AT light flashes on the dash on start up and the code for the TPS circuit too low code shows..

 

He adjusted the IAC while the car was running.. adjusted the idle stop screw while the car was running..

 

the car idles about 1000 in park and around 700 or so in gear..

 

He says this is the car that brings home the money...

 

But yet the brakes on the car are shot to spoob to the point where you have to press the brakes to the floor in order to stop..

 

IMHO I'm done with that car.. they want to screw it up go right ahead!
