DTC Code | DTC Name |
---|---|
P0522 | Engine Oil Pressure Sensor / Switch Low |
P0523 | Engine Oil Pressure Sensor / Switch High |
DESCRIPTION
The oil pressure control system reduces and increases engine oil pressure using the oil pressure switching valve in the timing chain cover assembly. When the engine speed reaches 2600 rpm while racing the engine after warming it up, the oil pressure switching valve operates and the engine oil pressure system changes from low pressure control mode to high pressure control mode. When the engine speed drops to 2400 rpm, the engine oil pressure system changes from high pressure control mode to low pressure control mode*. The oil pressure sender gauge assembly detects the engine oil pressure.
*: If the oil temperature is presumed high, the high pressure control mode is used at all engine speeds.

CAUTION / NOTICE / HINT
When replacing the ECM, perform ECM Initialization and Registration.

Inspect the fuses for circuits related to this system before performing the following procedure.
When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing a new ECM, perform all of the initialization and registration procedures for the "Learning Values Write" function by following the instructions shown on the GTS display.
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
PROCEDURE
CHECK HARNESS AND CONNECTOR (OIL PRESSURE SENDER GAUGE ASSEMBLY - ECM)
Disconnect the oil pressure sender gauge assembly connector.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.

CHECK WHETHER DTC OUTPUT RECURS (P0522 AND/OR P0523)
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs.
Powertrain > Engine and ECT > Clear DTCsTurn the ignition switch off and wait for 30 seconds or more.
Turn the ignition switch to ON and wait for 4 seconds or more.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.
