Oil Level Sensor, Diagnostics (2004-, Certain Markets And Models Only)

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2009 Volvo S60, 2008 Volvo S60, 2007 Volvo S60, 2006 Volvo S60, and 2005 Volvo S60. However, it is still accessible from the selected car via links, so may be relevant.

The engine control module (ECM) can diagnose the oil level sensor. A diagnostic trouble code (DTC) will be stored if an internal fault is detected in the oil level sensor or if there is an open-circuit or a short-circuit to ground or voltage in its wiring connectors. A diagnostic trouble code (DTC) will also be stored if the oil level is too low or high or if the oil level drops rapidly over a certain time (leakage).

The pulse ratio of all the oil level sensor pulses in a pulse train must be within the normal operating range of 17-83 %. If this is exceeded, a diagnostic trouble code (DTC) will be stored in the engine control module (ECM).

HINT: Extremely diluted engine oil can result in a diagnostic trouble code (DTC) for the oil level being stored in the engine control module (ECM).

For further information about diagnostic trouble codes (DTCs), see Information, diagnostic trouble codes (DTCs) in appropriate diagnostics tool.
