P1617

DTC P1617 Engine Oil Level Switch Circuit






Circuit Description

The engine oil level (EOL) switch is a simple float-type switch. The switch grounds when the oil level is at the proper level. The PCM applies an ignition voltage to the switch input circuit through a pull-up resistor. With the ignition turned ON, and the engine OFF, the PCM should detect low voltage. With the engine running, the PCM should detect a transition from low voltage to high voltage. If the PCM detects a low signal voltage (full oil level), and/or the PCM does not detect a switch transition with the engine running, DTC P1617 will set.

Conditions for Running the DTC

- No TP sensor, or VSS DTCs are set.
- Throttle position is greater than 5 percent.
- Vehicle speed is greater than 5 km/h (3 mph).
- Engine speed is greater than 2000 RPM.
- Vehicle is in steady state cruise (no lateral acceleration).

Condition for Setting the DTC

The PCM detects a low signal voltage, and/or no transition of the switch for at least 8 seconds.

Action Taken When the DTC Sets

- The PCM will not illuminate the malfunction indicator lamp (MIL).
- The PCM will store the conditions present when the DTC set as Failure Records data only.

Conditions for Clearing the MIL/DTC

- The history DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
- The DTC can be cleared by using the scan tool Clear DTC Information function.
