DESCRIPTION
The engine oil temperature sensor replaces the oil temperature with electrical signals and outputs them to the ECM.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
---|---|---|---|---|---|---|
P019511 | Engine Oil Temperature Sensor Circuit Short to Ground | The engine oil temperature sensor output voltage is less than 0.535 V for 5 seconds or more (1 trip detection logic). |
|
| DTC stored |
|
HINT:
When this DTC is output, check the engine oil temperature in the Data List. Enter the following menus: Powertrain / Engine / Data List / Engine Oil Temperature Sensor.
DTC No. | Engine Oil Temperature Sensor | Malfunction |
---|---|---|
P019511 | -40°C (-40°F) |
|
If the Data List value is normal it may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.

MONITOR DESCRIPTION
The ECM monitors the engine oil temperature sensor and uses the sensor voltage to calculate the engine oil temperature. If the engine oil temperature sensor output voltage deviates from the normal operating range, the ECM determines that the engine oil temperature sensor circuit is malfunctioning and stores this DTC.
Example:
If the engine oil temperature sensor output voltage is less than 0.535 V for 5 seconds or more, the ECM will store this DTC.

HINT:
Read Freeze Frame Data using the Techstream. 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 HARNESS AND CONNECTOR |
*a | Front view of wire harness connector (to Engine Oil Temperature Sensor) |
HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
(a) Disconnect the engine oil temperature sensor connector.
(b) Turn the power switch on (IG).
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Switch Condition | Specified Condition |
---|---|---|
C116-3 (VC) - C116-2 (GND) | Power switch on (IG) | 4.5 to 5.5 V |
C116-4 (TOUT) - C116-2 (GND) | Power switch on (IG) | 0.54 to 4.86 V |
(d) Turn the power 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 | Switch Condition | Specified Condition |
---|---|---|
C116-2 (GND) - Body ground | Power switch off | Below 1 Ω |
C116-3 (VC) - C116-4 (TOUT) | Power switch off | 171 to 189 kΩ |
OK | REPLACE OIL PRESSURE AND TEMPERATURE SENSOR |
|
2. | CHECK HARNESS AND CONNECTOR (ENGINE OIL TEMPERATURE SENSOR - ECM) |
(a) Disconnect the engine oil 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 |
---|---|---|
C116-2 (GND) - C88-100 (EPEO) | Always | Below 1 Ω |
C116-4 (TOUT) - C88-123 (THEO) | Always | Below 1 Ω |
C116-4 (TOUT) or C88-123 (THEO) - Other terminals | Always | 10 kΩ or higher |
OK | REPLACE ECM |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR |
