TPS failure part 2


Recommended Posts

I did write before about my fault code regarding the throtle position sensor. I checked the connectos and found them ok. I ordered a Bosch OEM TPS for the throtle body and replaced it. Cleaned the electrical connector with electric contact cleaner. It worked fine fo 20 miles then the CEL came on again. The code is the same: P1121 fault code 430 Throtle position sensor 01. I could not retrace the entire connecting wire to the TPS and only checked the actual connector. My car is a 1999 Carrera C2. I did installed headers, free flowing mufflers and cat by pass. I get the CEL for the oxygen sensors due to the cat by pass. The car has 81,000 if it matters. Any help or ideas will be greatly appreciated. I live 200 miles from the nearest Porsche dealer. By the way, the car appears to be performing flawlessly. If it was not for the Durametric reader, I would not know about this fault. Thank you all!

:lol: :lol: 35 years of working on Porsches probably helps. That and up to date service manuals.

Loren, if you read this post...I did the adaptation as you instructed (twice) and after driving for 15-20 miles I get the same fault code on the TPS. CHecked again the connection and is firm and adequate. Any other ideas or is it time to take it to the experts?

Wait, did you have 2 faults?

P1121 is Oxygen sensor heating 2 behind catalytic converter – below lower threshold

What is the current fault code?

The Durametric is saying throttle position sensor 1 after the p1121 code 430. Yes, I have oxygen sensor fult due to the cat by pass. Whats interesting is that the car appears to be running perfectly fine as far as I an tell.

Well, P1121 (Porsche code 430) is Oxygen sensor heating 2 behind catalytic converter – below lower threshold.

So I guess that would explain it. Best file a bug report with Durametric...

Thank you. Will do that. Guess that explains why it still runs smoothly.
