    Friends Used 1999 DeVille

    I have a friend of mine that just got a used 1999 deville. I pulled the following codes off of his computer. The vehicle wasn't running so I don't know if any are current. I'm going to clear and see if any come back.

    P0463 Fuel Level Sensor Circuit High Voltage
    P0603 Control Module Long Term Memory Reset
    P0741 TCC System Stuck Off
    P1520 Transmission Range Switch Circuit
    P1527 Transmission Range to Pressure Switch Correlation
    P1599 Engine Stall or Near Stall Detected
    P1602 Loss of EBTCM Serial Data
    P1604 Loss of IPC Serial Data
    P1605 Loss of HVAC Serial Data

    B1341 Air Mix Door Two Movement Fault

    Does anyone know if any of these codes...or a combination of them may point to the vehicle ever having a serious problem? My friend says he has a feeling that it may have been in a wreck then fixed, but he's not for certain. I'll post finding after I clear it. If any come back I'll let you know. I'll keep searching the forum for mor info, but if anyone has an idea I'd appreciate it.

    Have him try to pull the history from Carfax.
    Get the car running.
    Clear the codes.
    And, see what, if any, codes develop.

    Save those codes, you pulled, for future analysis.
