      I have a 2003 Chevy Malibu it ran hot the other day and we added water and burped the line. We also flushed the motor out with a water hose in the bottom of the motor while it was running.and it started to build up pressure and tried to shut off and then it started ticking. We changed the spark plugs and put Block seal in the radiator but it is still ticking. What could be the cause of the ticking?

    How Things Work

    Traction Control Light- What Does It Mean

    When wheel slip is noted while the brake is not applied, the ABS Computer-(EBCM) will enter traction control mode.

    First, the EBCM requests the PCM to reduce the amount of torque to the drive wheels via the requested torque signal circuit. The PCM reduces torque to the drive wheels by retarding spark timing and turning off fuel injectors. The PCM reports the amount torque delivered to the drive wheels via the delivered torque signal circuit.


    Common Engine Codes

    Knock Sensor Codes P0325 and P0327

    The powertrain control module (PCM) contains integrated knock sensor (KS) diagnostic circuitry. The KS produces an AC voltage at all engine speeds and loads. The PCM then adjusts spark timing based on the amplitude and frequency of the KS signal.
