DESCRIPTION
The oil pressure sensor (engine oil pressure and temperature sensor) utilizes a semiconductor type pressure sensor that changes resistance in accordance with changes in pressure. An internal electrical signal that varies with the change in resistance is amplified and sent to the ECM as the engine oil pressure signal.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Note |
---|---|---|---|---|---|
P052012 | Engine Oil Pressure Sensor/Switch "A" Circuit Short to Battery | The oil pressure sensor (engine oil pressure and temperature sensor) output voltage is higher than 4.495 V for 5 seconds or more (1 trip detection logic). |
| Comes on | SAE: P0523 |
P052014 | Engine Oil Pressure Sensor/Switch "A" Circuit Short to Ground or Open | The oil pressure sensor (engine oil pressure and temperature sensor) output voltage is below 0.159 V for 5 seconds or more (1 trip detection logic). |
| Comes on | SAE: P0522 |

MONITOR DESCRIPTION
The ECM calculates the engine oil pressure based on the output voltage of the oil pressure sensor (engine oil pressure and temperature sensor). If the signal output from the oil pressure sensor is outside of the specified range, the MIL is illuminated and a DTC is stored.

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.

2. | CHECK HARNESS AND CONNECTOR |
HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
(a) Disconnect the oil pressure sensor (engine oil pressure and temperature sensor) connector.
(b) Turn the ignition switch to ON.
(c) Measure the voltage according to the value(s) in the table below. Standard Voltage:
|
|
(d) Turn the ignition switch off and wait for at least 30 seconds.
(e) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
f2-1(PEO) - f2-2(E2) | Ignition switch off | 190 to 210 kΩ |
f2-2(E2) - Body ground | Always | Below 1 Ω |

3. | CHECK HARNESS AND CONNECTOR (OIL PRESSURE SENSOR (ENGINE OIL PRESSURE AND TEMPERATURE SENSOR) - ECM) |
(a) Disconnect the oil pressure sensor (engine oil pressure and temperature sensor) connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
f2-2(E2) - D104-78(EPEO) | Always | Below 1 Ω |
