MONITOR DESCRIPTION

The ECM calculates the engine oil pressure based on the output voltage of the oil pressure sender gauge assembly. If any of the following are detected, the ECM will illuminate the MIL and store a DTC.

The actual output voltage of the oil pressure sender gauge assembly is different than the estimated output voltage based on the engine speed.

The oil pressure sender gauge assembly output voltage does not change for a certain period of time.

CAUTION / NOTICE / HINT

HINT:: Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

1.CHECK DTC OUTPUT (DTC P052024, P05202A OR P052400)

Connect the GTS to the DLC3.

Turn the ignition switch to ON.

Turn the GTS on.

Enter the following menus: Powertrain / Engine / Trouble Codes.

Read the DTCs.

Powertrain > Engine > Trouble Codes: 50001 372

Result:

DTC P052024, P05202A or P052400 is output	A
DTC P052024, P05202A or P052400 and other DTC P15EA12 or P15EA14 are output	B

HINT:: If DTC P15EA12 or P15EA14 is output, perform troubleshooting for it first.

2.CHECK ENGINE OIL LEVEL
