I have a beautiful 1997 Regal GS 3.8L Supercharger (I love saying that
![]() Vehicle Scanned 1997 Regal 1=3.8L Set DTCs (codes) History DTC P0121 TPS/Pedal Position Sensor A CKT Range/Perf MIL REQUESTED Since IGN NOT RUN Since Clear P/F These codes indicate a malfunction in certain systems or components. Proper diagnosis should performed by a mechanic or through proper diagnostics ounlined in the service manual for your vehicle. Now the guy at AA told me that if I had that sensor replaced that would fix it. But a friend of mine told me today that just because AA's computer said that was the problem doesn't mean it is. No worries people...I'm not the one going to be making the repairs and I'm not going to bog you down with a bunch of "but" questions. I'm going to print out your replies and show it to my friend and he'll do it for me. ![]() Thank you, Magnolia |

Re: 1997 Regal TPS Malfunction
Welcome to AF.
I would take the P0121 DTC at face value. It indicates the TPS has a circuit range/performance/rationality fault. In a nutshell it indicates the TPS is sticking. The PCM module looks at the last throttle position value to see if it is greater than or less than the predicted throttle position. If off or out of range the DTC will set and trigger the SES/CEL Mil light. On a TPS at the electrical connector and pressing the accelerator you can check the PCM 5 volt reference signal at the input and the output back to the PCM which will vary progressively/linear from .4 vdc at idle to around 4.5 vdc at WOT (wide open throttle).
