Volvo All Engines (2004 Emissions) Fault Code: PID 98 FMI 1 Engine Oil Level / Temperature Sensor
Fault Condition: If the EMS Module senses that the engine oil level is moderately or critically below range, FMI 1 will be set. If the reference voltage signal is shorted to ground, FMI 4 will be set. If the reference voltage circuit is shorted to battery voltage or has an open circuit, FMI 5 will be set. If the ground circuit of the sensor has an open, FMI 5 will also be set.
Possible repairs:
Turn the ignition key OFF first.
1) Disconnect the Engine Oil Temperature/Level Sensor connector.Check for continuity between each of the pins (1,2,3, and 4) of the Engine Oil Temperature/Level Sensor and a good ground. If continuity exists between any of the pins and ground, replace the Engine Oil Temperature/Level Sensor.
2) Disconnect the Engine Oil Temperature/Level Sensor connector. Measure the resistance across the pins 1 and 2 of the Engine Oil Temperature/Level Sensor. With the engine at room temperature the sensor resistance should be 10.8-17.4 ohms. If the resistance of the sensor is NOT as specified, replace the Engine Oil Temperature/Level Sensor.
3) Disconnect the Engine Oil Temperature/Level Sensor harness connector. Disconnect the EMS Module harness connector B. Measure continuity between Engine Oil Temperature/Level Sensor harness connector pin 2 and a good ground. If continuity exists, repair the short to ground in the signal line circuit. If there is NO continuity, check the pins or the EMS Module for dirt, loose pins or deformed contacts. Replace the EMS Module if the pins of the module are not damaged. Retest the system.
4) Disconnect the Engine Oil Temperature/Level Sensor connector. Measure the resistance across the pins 1 and 2 of the Engine Oil Temperature/Level Sensor. With the engine at room temperature the sensor resistance should be 10.8-17.4 ohms. If the resistance of the sensor is NOT as specified, replace the Engine Oil Temperature/Level Sensor.
5) Disconnect the Engine Oil Temperature/Level Sensor harness connector. Disconnect the EMS Module harness connector B. Turn the ignition key ON. Measure voltage between Engine Oil Temperature/Level Sensor harness
connector pin 2 and a good ground. If the there is voltage present, repair the short to voltage on the signal line.
6) Disconnect the Engine Oil Temperature/Level Sensor connector. Disconnect connector B from the EMS Module. Check for continuity between connector B pin 4 of the EMS Module harness connector and pin 2 of the Engine Oil Temperature/Level Sensor harness connector. If there is NO continuity, locate and repair the circuit between the sensor and the EMS Module.
7) Disconnect the Engine Oil Temperature/Level Sensor connector. Disconnect connector B from the EMS Module. Check for continuity between connector B pin 3 of the EMS Module harness connector and pin 1 of the Engine Oil Temperature/Level Sensor harness connector. If there is NO continuity, locate and repair the circuit between the sensor and the EMS Module.
8) Visually inspect the EMS Module harness connectors A and B for dirt, loose pins or deformed contacts. If a repairable open is found or either of the pins feels loose, repair the EMS Module harness connector.
If the EMS Module harness connector is OK, verify the diagnostic code and the FMI, and retest. If FMI 5 is still active, replace the Engine Management System (EMS) Module and retest the system.
