    What are the common causes of P0881 ?

    By far the most common cause of this code is from a defective traction control ON/OFF switch. Liquids spilled into the traction control switch are a very common cause of this type of failure.. Other causes may include open, shorted, corroded, or otherwise damaged wiring and/or electrical connectors. Technicians also report the presence of excessive corrosion in the sensor connector as the cause of this code being stored.

    How do you troubleshoot P0881 ?

    Deactivation of cylinders is achieved by releasing a synchroniser pin that normally interlocks the cam follower and rocker arms. P0881 code resolves the synchroniser pin is released using hydraulic pressure which is controlled by a dedicated solenoid.
