Purpose, Function
The oil jet valve injects engine oil on the back of the piston to cool the piston.
Construction
The oil jet valve is installed into the cylinder block.

The oil jet valve is built into the check ball and spring.

Operation
1. When the oil pressure applied to the check ball exceeds the spring force, the check ball and spring are pressed down.
2. The oil passage is opened to the nozzle and engine oil is injected to the back side of the piston.

3. When the oil pressure applied to the check ball is lower than the spring force, the spring presses up the check ball.
4. The oil passage to the nozzle is closed and the injection of engine oil stops.

Oil Pan Removal/InstallationFuel Filler Cap
Purpose, Function
Releases evaporative gas from the fuel tank if there is a malfunction in
the evaporative gas passage between the fuel tank and the intake manifold. As
a result, deformation of the fuel tank caused by evaporative gas pressure is
prevented.

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 ...
