Differential Oil Inspection
Differential Oil Temperature SensorCrankshaft, Main Bearing
Purpose, Function
The crankshaft converts the reciprocating movement of the piston to a rotational
movement via the connecting rod.
The main bearing forms an oil film on the outer surface of the crankshaft
journal to prevent wear due to sliding.

Fuel Pump Relay
Purpose, Function
Controls the fuel pump on/off according to control signals from the PCM.
The fuel pump is operated only at engine start or when the engine is running
to improve safety.
Construction
The fuel pump relay is installed in the relay and fuse block.

Intake Air Temperature (Iat) Sensor Inspection
IAT Sensor No.1
Resistance inspection
NOTE:
Because the IAT sensor No.1 is integrated in the MAF sensor, replacing the
IAT sensor No.1 includes replacement of the MAF sensor/IAT sensor No.1.
1. Disconnect the negative battery cable..
2. Disconnect the MAF sensor/IAT sensor No.1 ...
