INSPECTION

PROCEDURE

1. INSPECT OIL PRESSURE AND TEMPERATURE SENSOR

(a) Check the oil pressure and temperature sensor output voltage.

(1) Apply 5 V between terminals 3 (VC) and 2 (GND).

NOTICE:

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.

Voltage Applied between Terminals

(2) Measure the voltage between terminals.

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.
