    Q:
    What does the manifold absolute pressure (MAP) sensor do and how can it be checked for the 1998 Chevrolet S10? Posted by Customer
    A:
    The manifold absolute pressure (MAP) sensor monitors intake manifold pressure changes and varies its voltage output accordingly. To check it, you should check the reference voltage and signal voltage with the ignition on and engine off, and observe voltage changes as the engine's vacuum changes.

    Q:
    What is the engine coolant temperature (ECT) sensor and how can it be checked for the 1997 GMC Sonoma? Posted by Customer
    A:
    The engine coolant temperature (ECT) sensor is a thermistor that changes resistance with temperature. To check it, measure the resistance while cold and warm, and ensure the reference voltage from the PCM is around 5.0 volts.
