P1617

CIRCUIT DESCRIPTION
The engine oil level switch grounds when the oil level is at the proper level. With the ignition ON, and the engine OFF, the PCM should detect a low voltage input on the switch circuit (full oil level). With the engine running, the PCM should detect a transition from a low voltage to a high voltage input on the oil level switch signal circuit.

CONDITIONS FOR RUNNING THE DTC
^ TP sensor or VSS DTCs are not set.
^ The throttle position is more than 5%.
^ The vehicle speed is more than 5 km/h (3 mph).
^ The engine speed is more than 2000 RPM.
^ The vehicle is in steady state cruise (no lateral acceleration).

CONDITIONS FOR SETTING THE DTC
The PCM detects a low signal voltage, and/or the PCM does not detect a switch transition with the engine running.

ACTION TAKEN WHEN THE DTC SETS
^ The PCM will not illuminate the malfunction indicator lamp (MIL).
^ The PCM records the operating conditions at the time the diagnostic fails. The PCM displays the failure information in the Failure Records on the scan tool.

CONDITIONS FOR CLEARING THE DTC
^ The DTC becomes history when the conditions for setting the DTC are no longer present.
^ The history DTC clears after 40 malfunction free warm-up cycles.
^ The PCM receives the clear code command from the scan tool.

DIAGNOSTIC AIDS
^ Use the Freeze Frame and/or Failure Records data in order to locate an intermittent condition. If you cannot duplicate the DTC, the information included in the Freeze Frame and/or Failure Records data may aid in determining the number of miles since the DTC set. The Fail Counter and Pass Counter can also aid in determining the number of ignition cycles that the diagnostic reported a pass and/or fail. Operate the vehicle within the same freeze frame conditions (RPM, engine load, vehicle speed, temperature, etc.). This will isolate when the DTC failed.
^ Refer to Testing for Intermittent and Poor Connections in Diagrams.
