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

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 ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P052024 OR P05202A) |
(a) Read the DTCs.
Powertrain > Engine > Trouble Codes
Result | Proceed to |
---|---|
DTC P052024 or P05202A is output |
A |
DTC P052024 or P05202A and other DTCs are output |
B |
HINT:
If any DTCs other than P052024 or P05202A are output, troubleshoot those DTCs first.
B | GO TO DTC CHART |
|
2. |
INSPECT OIL PRESSURE SENSOR (OIL PRESSURE AND TEMPERATURE SENSOR) |
(a) Read the value displayed on the GTS.
(1) Disconnect the oil pressure control valve assembly connector.
(2) Put the engine in Inspection Mode (Maintenance Mode).

(3) Start the engine.
(4) Enter the following menus.

Engine Speed |
Engine Oil Temperature Sensor |
Engine Oil Pressure |
(5) With the engine oil temperature at 75 to 85°C (167 to 185°F), read the "Engine Oil Pressure" with the engine speed at 2500 rpm.
(b) Read the oil pressure using an oil pressure gauge with adapter.
(1) Install the oil pressure gauge.

Coolant Temperature |
HINT:
When the oil pressure and temperature sensor is removed, the engine oil temperature cannot be checked, so refer to "Coolant Temperature".
(5) Maintain "Coolant Temperature" at 90 to 95°C (194 to 203°F) for 3 minutes, and then read the oil pressure gauge value at 2500 rpm.
HINT:
(c) Compare the Data List value and the oil pressure gauge reading.
OK:
Data List value and gauge reading are within +/-50 kPa (7.3 psi) of each other
HINT:
Be sure to clear the DTCs after reinstalling the oil pressure sensor (oil pressure and temperature sensor) or reconnecting the oil pressure sensor (oil pressure and temperature sensor) or oil pressure control valve assembly connector, as DTCs may be stored.
