    What does P0823 Mean?

    OBD-II Code Powertrain Control Module (PCM) failure is defined as a Gear Lever X Position Circuit Intermittent

    The Gear Lever Position Sensor tells the engine computer (PCM) what gear the transmission is in. If the Gear Lever Position Sensor gives the PCM an implausible signal, code P0823 is set.

    What are the common causes of P0823 ?

    The PCM is registering data that is out of norms from transmission shift solenoids, the torque converter lockup solenoid, vehicle speed sensors or other sensors. The PCM then reads this as an incorrect transmission shifter range, storing a trouble code and illuminating the malfunction indicator lamp (MIL). The PCM may also put the transmission into limp-in mode.

    More often than not, an out-of-adjustment transmission range sensor or failed transmission range sensor will cause a P0823 code.

    How do you troubleshoot P0823 ?

    While fuel economy was increased, acceleration was seriously compromised, and the loss of engine vacuum led to a dangerous loss of braking assist when the P0823 code system was in four-cylinder mode. In addition to these issues, while the company proposed a hydraulically controlled system that could be switched from within the car, the version they implemented had to be manually changed in the engine compartment using hand tools.
