      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?

    The Evaporative Emission (EVAP) control system limits the fuel vapors from escaping into the atmosphere. The EVAP transfers the fuel vapors from the sealed fuel tank to an activated carbon (charcoal) storage device (EVAP canister). The EVAP canister stores the vapors until the engine is able to use the extra fuel vapor. When the engine is able to use the extra fuel vapor,

    Oxygen Sensor Code P0036 and P0056

    P0036 - P0056
    Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach operating temperature to provide an accurate voltage signal. A heating element inside the HO2S minimizes the time required for the sensor to reach operating temperature.
