Title: A25A-FKS (ENGINE CONTROL): SFI SYSTEM (w/o Canister Pump Module): P019511; Engine Oil Temperature Sensor Circuit Short to Ground; 2019 - 2020 MY RAV4 [11/2018 - 08/2020]

DTC

P019511

Engine Oil Temperature Sensor Circuit Short to Ground

DESCRIPTION

The engine oil temperature sensor (engine oil pressure and temperature sensor) replaces the oil temperature with electrical signals and outputs them to the ECM.

DTC No.

Note

P019511

Engine Oil Temperature Sensor Circuit Short to Ground

The engine oil temperature sensor (engine oil pressure and temperature sensor) output voltage is less than 0.535 V for 5 seconds or more (1 trip detection logic).
  • Open or short in engine oil temperature sensor (engine oil pressure and temperature sensor) circuit
  • Engine oil temperature sensor (engine oil pressure and temperature sensor)
  • ECM

Does not come on

DTC stored

SAE Code: P0197

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)
  • Short to ground in THEO circuit
  • Short in EPEO to THEO circuit
  • Open in VCPE circuit

If the Data List values are 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 (engine oil pressure and temperature sensor) and uses the sensor voltage to calculate the engine oil temperature. If the engine oil temperature sensor (engine oil pressure and temperature sensor) output voltage deviates from the normal operating range, the ECM determines that the engine oil temperature sensor (engine oil pressure and temperature sensor) circuit is malfunctioning and stores this DTC.

Example:

If the engine oil temperature sensor (engine oil pressure and temperature sensor) output voltage is less than 0.535 V for 5 seconds or more, the ECM will store this DTC.

MONITOR STRATEGY

Frequency of Operation

Continuous

CONFIRMATION DRIVING PATTERN

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON.
  3. Turn the Techstream on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the ignition switch off and wait for at least 30 seconds.
  6. Turn the ignition switch to ON.
  7. Turn the Techstream on.
  8. Wait 10 seconds or more.
  9. Enter the following menus: Powertrain / Engine / Trouble Codes.
  10. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  11. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  12. Input the DTC: P019511.
  13. Check the DTC judgment result.

    Techstream Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed
    • System abnormal

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    HINT:

    • If the judgment result is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system has a malfunction.

WIRING DIAGRAM

CAUTION / NOTICE / HINT

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
