| Post subject: | Multiple Engine codes |
I just had my valve spring replaced today after about a month of waiting. We thought, and the mechanic said everything should be good-It idles fine. Well as i pulled out of the garage, it seems that every time its about to doo doo out of first it sputters and jumps forward as if im pumping the pedal. i pulled the codes: P0108- MAP Sensor Voltage Too High P0113- Intake Air Temp Sensor Voltage Too High P0118- Engine Coolant Temp Sensor Voltage Too High P0123- Throttle Position Sensor #1 Voltage High P0533- A/C Sending Unit Volts Too High P0685- ASD Relay Control Circuit P0688- ASD Relay Sense Circuit Low Can anyone help me out? I honestly don't know where to start... Thank you, Dalton |

Well almost all of those codes are referring to sensors that get a 5v reference voltage,sounds like a bad PCM.Last vehicle I had to diag with pretty much the same codes(but with about 6 more) ended up being a bad PCM,ran great though,but terrible mpg's. |

So do i need to buy a new PCM? And would that explain the shuttering and jumping forward? |

Its is out of warranty with 73,000 miles. it would still be a good idea to have it diagnosed before i do anything correct? |

Other then the mpg's, would it hurt anything to wait a Month or 2 to take it to the dealer and buy a new one if that's the problem? |
