Computers and Control Systems: Locations

A battery temperature sensor, located either in the battery tray, using the ambient sensor, or in the PCM itself, is used to sense battery temperature.

The SKIS incorporates a warning lamp located in the instrument cluster.

The fuel pump module containing the electric fuel pump, fuel filter/fuel pressure regulator, fuel gauge sending unit (fuel level sensor) and a separate fuel filter located at bottom of pump module.

The fuel filler tube contains a flap door located below the fuel fill cap.

The combination fuel filter and fuel pressure regulator is located on the top of fuel pump module.

The check valve is located at the outlet end of the electric fuel pump.

The fuel pump is located inside of the fuel pump module.

Fig.35 Rollover Valve Location:

The fuel tank is equipped with a rollover valve. The valve is located on the top of the fuel tank.

The Crankshaft Position (CKP) sensor is located near the outer edge of the flywheel (starter ringear).

The 5-pin, 12-volt, fuel pump relay is located in the Power Distribution Center (PDC).

The MAP sensor signal is provided from a single piezoresistive element located in the center of a diaphragm.

Both of the upstream O2S sensors are located in the exhaust manifold just before the mini-catalytic convertors.

The downstream sensors are located in the exhaust downpipes just after the mini-catalytic convertors.

The throttle body is located on the intake manifold.
