Fundamentals of PowertrainControl strategies & OBD <strong>II</strong><strong>Diagnostics</strong>Engine Speed Sensor ( DTCs 320-323):Engine speed sensor diagnostics are performed for eterioration ofmagnetic reluctance characteristics.In case of electrical circuit malfunction fault code 320 is assigned.If the sensor circuit is indicating out of range reading fault code 321 isassigned. If the sensor circuit is indicating no signal , fault code 322 isassigned. The expected value is estimated using engine parameters.If the sensor is indicating intermittent faulty reading, fault code 323 isassigned.
