Toyota Yaris: Oil Pressure And Temperature Sensor / On-vehicle Inspection

ON-VEHICLE INSPECTION

CAUTION / NOTICE / HINT

PROCEDURE

1. INSPECT OIL PRESSURE AND TEMPERATURE SENSOR

(a) Disconnect the oil pressure and temperature sensor connector.

HINT:

By disconnecting the oil pressure and temperature sensor connector, the non-regulated oil pressure can be measured.

(b) Read the value displayed on the GTS.

(1) Connect the GTS to the DLC3.

(2) Start the engine.

(3) Turn the GTS on.

(4) Enter the following menus: Powertrain / Engine / Data List / Engine Speed, Engine Oil Temperature Sensor and 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 2000 rpm.

(c) Read the oil pressure using an oil pressure gauge with adapter.

(1) Remove the oil pressure and temperature sensor.

CAUTION:

Make sure the engine is cold when removing the oil pressure and temperature sensor to prevent burns caused by hot engine oil.

(2) Install the oil pressure gauge with adapter. NOTICE: Clean the hose and adapter of the oil pressure gauge before and after measurement.

(3) Start the engine.

(4) Enter the following menus: Powertrain / Engine / Data List / Engine Speed and Coolant Temperature.

HINT:

When the engine 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 2000 rpm.

(d) 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

(1) Remove the oil pressure gauge with the adapter.

CAUTION:

Removing the oil pressure gauge with adapter while the engine is hot could result in burns caused by contact with hot engine oil.

(2) Install the oil pressure and temperature sensor.

(e) Connect the oil pressure and temperature sensor connector.

HINT:

Be sure to clear the DTCs after reinstalling the oil pressure and temperature sensor or reconnecting the oil pressure and temperature sensor or oil pressure control valve assembly connector, as DTCs may be stored.
