Fig. 29: Identifying CKP Sensor And CKP Sensor Subharness Engine Coolant Temperature (ECT) Sensors 1 and 2 ECT sensors 1 and 2 are temperature dependent resistors (thermistors). The resistance of the thermistor Fig. 30: Identifying Terminal And O-Ring Of Engine Coolant Temperature Sensors Ignition Timing Control The PCM contains the memory for basic ignition timing at various engine speeds and manifold absolute Injector Timing and Duration The PCM contains the memory for basic discharge duration at various engine speeds and manifold By monitoring long term fuel trim, the PCM detects long term malfunctions in the fuel system and sets a Intake Air Temperature (IAT) Sensor The IAT sensor is a temperature dependent resistor (thermistor). The resistance of the thermistor decreases
