The GM part 55503494 Knock Sensor is vital to engine system performance because it monitors key parameters with exact precision. This thermistor component delivers resistance change with temperature to provide the engine coolant temperature (ECT) with precise readings. Scheduled maintenance requires testing resistance at room temperature and operating temperature and it should verify the PCM generates reference voltage at 5.0 volts. During engine operation users must observe voltage values for reference and signal from the manifold absolute pressure (map) sensor in this GM part as it adjusts its output voltage in response to intake manifold pressure fluctuations. A scan tool should be applied to validate the performance of the intake air temperature (IAT) sensor by checking its resistance changes during temperature variations. Each manufacturing process requires testing of the oxygen sensor millivolt signal alongside checking the heater receives its specified voltage during engine warm-up. The proper signal output from vehicle speed sensor (VSS) and knock sensors should be checked together with their reference voltage for optimal performance.
