Components for the PWM sensors
(1) Analog pressure sensor
(2) Signal converter The PWM sensor circuit consists of an analog pressure sensor and a signal converter. The signal converter is powered by a 8.0 0.4 VDC regulated voltage from the ECM. The signal converter supplies 5.0 0.25 VDC to the analog sensor. The analog pressure sensor provides an analog signal to the signal converter that represents the pressure that is being sampled. The signal converter converts the analog signal to a PWM signal and the converter then transmits the signal to the ECM.The signal converter generates a PWM signal that is in a specific range of duty cycle that is sent to the ECM. This range is directly related to the pressures that are sampled by the pressure sensor. As the pressure of the sensor fluctuates between the minimum and the maximum pressures, the duty cycle fluctuates on a scale that is directly related to the pressure that is sampled by the sensor. The sensor's signal converter generates a frequency of 500 100 Hz for the PWM signal. If the frequency of the sensor's PWM signal is out of the specification, a diagnostic code will be generated.Excessive pressure can generate electrical noise interference in the circuitry that is for the sensors. Although there is not a problem with the sensor, the following codes will be generated for the given pressures:If the actual turbocharger compressor outlet pressure (absolute pressure) is greater than approximately 467 kPa (68 psi), a 102-8 turbocharger compressor outlet Pressure Sensor abnormal frequency, pulse width, or period will be generated.If the actual inlet manifold pressure (absolute pressure) is greater than approximately 446 kPa (65 psi), a 106-8 Air Inlet Pressure Sensor abnormal frequency, pulse width, or period will be generated.If the actual engine coolant pressure (absolute pressure) is greater than approximately 446 kPa (65 psi), a 109-8 Engine Coolant Outlet Pressure Sensor abnormal frequency, pulse width, or period will be generated.If a 102-8, 106-8, or 109-8 diagnostic code is generated, measure the actual pressure with a pressure gauge before you troubleshoot the sensor. If the pressure is too high, repair the system in order to reduce the pressure. This will avoid activation of false diagnostic codes.A -3 diagnostic code for the pressure sensors is probably caused by a short circuit to the +Battery in the harness or by an open circuit in a harness. The next likely cause is a sensor problem. The least likely cause is a problem with the ECM.
