HI all, I just completed installing suspension upgrade. I had the brake lines off, to make work easier, and bled all the lines after. I also removed the plug that goes in the front hub (abs sensor), and it was in some white grease. I am now getting P2120 - Powertrain (Throttle/Pedal Position Sensor /D circuit. P2125 - Powertrain (Throttle / Pedal Position Sensor /Switch E circuit. B2TAE - Body. When I start the Jeep it seems to idle at around 1K, instead of 750. Stepping on the gas does nothing, and I can hear the turbo whistling (maybe it's just the new Samco hoses). Stepping on the brake reduces idle to about 750. Tried resetting by unplugging the battery terminal for 15 minutes but no luck. Also cleared the code but comes back. Any help would be welcome. KJ75 |

Did you somehow disconnect the throttle position sensor? It might also just be a complete coincidence that it decided to fail at this moment. |

Where would the throttle position sensor be located ? |

Checked under the gas pedal and a plug was completely loose. I'll put the Jeep back together and try again tomorrow. Can't believe I spent a whole day looking for this. Thanks Mike. |

Confirmed, all is OK after plugging TPS in and clearing the error codes. |

Sweet. I'm glad it was something easy. |
