The Engine Oil Temperature/Level Sensor contains two resistors: One for engine oil temperature and one for engine oil level.Diagnostic trouble code (DTC) Placeholder will be present only when a problem with the engine oil level (EOL) circuit has failed. Please reference Placeholder for engine oil temperature (EOT) sensor circuit diagnostics.The resistance of the engine oil level portion of the sensor changes inversely to the level of the engine oil. The Engine Control Module (ECM) monitors the voltage drop across the sensor and uses this signal to warn that the engine oil level is not within programmed limits. In some cases...

Fault Condition: The Electronic Malfunction Lamp (EML) will illuminate when the EOP Sensor’s signal line voltage is less than 0.3 volts or greater than 4.75 volts. If the signal line voltage returns to between 0.3 volts and 4.75 volts the fault will become inactive. Possible repairs: Turn the ignition key OFF first. 1) Disconnect EMS Module connectors A and B. Disconnect Engine Oil Pressure (EOP) Switch connector. Check for continuity between Engine Oil Pressure (EOP) Sensor harness connector pin 2 (signal line) and a good ground and also check for continuity between EMS Module connector B pin 11 and all...

Fault Condition: The Electronic Malfunction Lamp (EML) will turn on and PID 102 will set when the EMS Module senses that the Boost Pressure and Temperature Sensor signal voltage is less than 0.15 volts or greater than 4.75 volts. If the Boost Air Pressure/Temperature Sensor voltage is between 0.15 volts and 4.75 volts, the fault will become inactive. Possible repairs: Turn the ignition key OFF first. 1) Disconnect the Boost Air Pressure/Temperature Sensor. Disconnect Engine Management System (EMS) Module connector A. Check for continuity between pin 4 on the harness side of the Boost Air Pressure/Temperature Sensor and a good...
