p0123
p1544

My car (98 1.8tq AEB) gave me these codes when I plugged the OBD II into it from Autozone. My girlfriends jetta got a CEL (p0420 - cat maybe?) and since I had the machine, I figured I would plug it into my car. I had no CEL though. I did a search and found out that they have to do with the TB, but I couldn't find much info. Does anybody know what it takes to fix these?

 

I dont know what the codes mean but dont mess with the timing belt, if that is whats wrong get it replaced, im sure you know what happens if it blows, how many miles on the car?

 

P0123= Throttle/Pedal Position Sensor/Switch "A" Circuit High
P1544= Angle Sender 1 for Throttle Valve Drive G-187 Signal Too High
Sounds like there is a problem with the throttle body, check electrical connectors, remove the hose and make sure no carbon build up is on the butterfly valve, and perform a throttle body alignment.

 

The timing belt??? Oh...when I said TB, I meant throttle body....not timing belt. The timing belt broke on me around 13,000 miles ago [:@]. I definitly know what happens when that blows.
As for the throttle body...I cleaned that up a few days ago and there wasa whole lot of carbon on it. Not any more though. I took it off and cleaned with throttle body cleaner, and then put it back on with a new gasket. I will do the things you said though (check connectors) + plus make sure the bolts are nice tight.
After I cleaned it though, I checked it the next day and there was a fair amount of fresh oil in it. Here is the link to the thread I started about that -

I hope to replace the pcv system in a week or so, and am thinking of getting a catch can.......but I am not sure if I need one yet, if I replace my whole pcv system.
I have done a throttle body alignment before, but I have read that you should actaully see the linkage move and mine deffinitly does not move. I hear a winding sound...but no movement.
