TPS faikure codes

[baronb55]

Hi everyone. Have failure codes on the TPS on my Durametric reader. The codes are P1121 code 430 and Durametric says its the throttle position sensor. I looked at the codes in the forum and could not find the P1121. There were some codes pertaining to the throttle pedal posiiton sensor. Is the code that I am getting related to the pedal or the sensor in the throttle body? Any help will be appreciated. Need to know what sensor to replace.

You have a C4?

P1121 Throttle Position Sensor 1 – Signal Implausible

P1121 Throttle Position Sensor 1 – Below Limit

P1121 Throttle Position Sensor 1 – Above Limit

Possible causes:

– Open circuit or short circuit in wiring

– TP sensor faulty

– DME control module faulty

Clean and check the wiring - if all looks good replace the TPS.

Have a C2 1999 just like yours! Even same color and tail. I am getting the TPS sensor 1 signal implausible code. The wiring is checked at the connection point of the sensor in the engine compartment? Found a source selling this sensor for $80 (Bosch OEM). Thanks for your constant, expeert help. I am learnig quite a bit and enjoying. Anything to look for when removing and replacing this sensor?
