need help with p2122 code
My 2006 HHR left me stranded at gf's house yesterday. Code is p2122.
Engine idles perfect...just will not go regardless of where gas pedal is pressed. Cleared code and car now runs great. Any suggestions? Thanks for your help Eddie |

From your description it sounds like the pedal has gone bad.
|
Either the pedal or a loose or dirty connection.
How is the battery, could be the source of the low voltage issues |
Thanks guys,
I'm already thinking about the accelerator pedal position sensor. Found one for $60 new online. Thanks again |
I'm having the exact same problem. Did the pedal sensor resolve your issue?

Including clearing the code and it is fixed? And being a 2006? This thread is more than a year old The OP has not returned to let us in on his progress. So, we need much more specifics from you. |

Then most likely the pedal assembly or the electrical connector.
It basically means the #1 sensor is shorting to ground. The 2 sensors have LowRef 5VRef and signal. Basically 2 rheostats. |
Where is the #2 sensor? on the TB?
I'm thinking of trying to crack open the #1 pedal sensor and seeing if some alcohol or electrical contract cleaner will help. Unless of course it's totally sealed. |
