Pinpoint Test An : The Low Oil Pressure RTT (RECONFIGURABLE Telltale) Is Never Or Always On (2.3L And 3.7L Engine): Notes
Refer to Instrument Cluster for schematic and connector information.
Normal Operation and Fault Conditions
See Low Oil Pressure RTT. REFER to: Message Center - System Operation and Component Description .
If the engine RPM data or oil pressure warning indicator request message is missing less than 5 seconds, the IPC defaults the low oil pressure warning indicator to the last state (on or off), based upon the last message received.
If the engine RPM data or oil pressure warning message is missing for 5 seconds or longer, the IPC defaults the low oil pressure warning indicator on.
DTC Chart - PCM
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0521 | Engine Oil Pressure Sensor/Switch "A" Circuit Range/Performance | Sets in the PCM when the PCM detects signal variation outside of the module parameters on the hardwired input from the oil pressure switch. |
| P0522 | Engine Oil Pressure Sensor/Switch "A" Circuit Low | Sets in the PCM when the PCM detects a short to ground on the hardwired input from the oil pressure switch. |
| P0523 | Engine Oil Pressure Sensor/Switch "A" Circuit High | Sets in the PCM when the PCM detects an open on the hardwired input from the oil pressure switch. |
| P0524 | Engine Oil Pressure Too Low | Sets in the PCM when the PCM detects low oil pressure. |
