What does code 1-p0650 mean?


P0650 Malfunction Indicator Lamp (MIL) Control Circuit Malfunction

Malfunction Indicator Lamp (MIL) is located on the instrument panel. When the ignition switch is turned ON without engine running, MIL will light up. This is a bulb check. When the engine is started, MIL should go off. If MIL remains on, the on board diagnostic system has detected an engine system malfunction.

Possible Causes:
  • Harness or connectors (MIL circuit is open or shorted.)
  • MIL bulb may be faulty

    Trans range sensor circuit malfunction


    Transaxle Range Sensor Circuit Malfunction (PRNDL Input).  

    Check for: _ Possibly a connector near the shift lever has come loose/dirty contacts, or there is a broken wire from it somewhere going to the TCM 
    - Corroded or faulty Range Switch. - Open between Meter Fuse and Range Switch (C136-4).
    - Open between Range Switch (C136) and TCM (C229) on one or more circuits. 
    - Short to Battery between Range Switch (C136) and TCM (C229) on one or more circuits. 
    - Short between two or more wires between Range Switch (C136) and TCM (C229). 

    If Meter Fuse is blown, repair any shorts in the Meter Fuse circuit.

    P1624 MIL Request Signal from TCM to ECM.This is only a request from TCM to ECM to turn the MIL on. The fault code is stored in the TCM.The Freeze Frame Data is stored in the ECM under the P1624 request code. Be sure to retrieve freeze frame data before clearing code P1624 from ECM. 
    TCM = Transmission control module 
    ECM = Engine control module (or more commonly known as ECU) 
    MIL = Malfunction indicator light (more commonly "check engine light" or CEL) 

    Good luck and hope this helps
