TESTING
TANK PRESSURE CONTROL VALVE
1. Using a hand-held vacuum pump, apply a vacuum of 15 in. Hg. (51 kPa)
through the control vacuum signal tube to the purge valve diaphragm. If
the diaphragm does not hold 5 in. Hg . at least for 10 seconds, the
diaphragm is leaking. Repl ace the control valve.
2. With the vacuum still applied to t he control vacuum tube, attach a short
piece of hose to the valve's tank tube side and blow into the hose. Air \

INTAKE AIR TEMPERATURE (IAT) SENSOR
OPERATION
The IAT sensor is a thermistor which su pplies intake air temperature information
to the ECM. The sensor produces high re sistance at low temperatures and low
resistance at high temperatures. The ECM supplies a 5 volt signal to the sensor
and measures the output voltage. The vo ltage signal will be low when the air is
cold and high when the air is hot. On so me models, this sensor is also known
as the Manifold Air Tem perature (MAT) sensor.
REMOVAL & INSTALLATION 1. Disconnect the negative battery cable.
2. Detach the sensor electr ical connector locking tab.
3. Carefully remove the sensor.
To install: 4. Install the sensor.
5. Connect the electrical wiring.
6. Connect the negative battery cable.
