Inspection [08/2020 - ]: Procedure
WARNING: This page is about a different car, the 2024 Lexus ES 250, 2023 Lexus ES 250, 2022 Lexus ES 250, and 2021 Lexus ES 250. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT OIL PRESSURE AND TEMPERATURE SENSOR
- Check the oil pressure and temperature sensor output voltage.
- Apply 5 V between terminals 3 (VC) and 2 (GND).
*a Component without harness connected
(Oil Pressure and Temperature Sensor)*b Voltage Applied between Terminals NOTE:- Be careful when connecting the leads as the oil pressure and temperature sensor may be damaged if the leads are connected to the wrong terminals.
- Do not apply more than 6 V to terminals 3 (VC) or 2 (GND).
HINT:
If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series.
- Measure the voltage between terminals.
*a Component without harness connected
(Oil Pressure and Temperature Sensor)Standard Voltage
Tester Connection Condition Specified Condition 4 (TOUT) - 2 (GND) 20°C (68°F) Approximately 1.5 to 2.5 V* *: The output voltage changes depending on the voltage applied to the terminals.
If the result is not as specified, replace the oil pressure and temperature sensor.
- Apply 5 V between terminals 3 (VC) and 2 (GND).
- Check the oil pressure and temperature sensor output voltage.
