FUNCTION AND OPERATION PRICIPLE
Based on information from various sensors, the PCM measures the fuel injection amount. The fuel injector is a
solenoid- operated valve and the fuel injection amount is controlled by length of time that the fuel injector is held open.
The PCM controls each injector by grounding the control circuit. When the PCM energizes the injector by grounding
the control circuit, the circuit voltage should be low (theoretically 0V) and the fuel is injected. When the PCM de-
energizes the injector by opening control circuit, the fuel injector is closed and circuit voltage should momentarily peak.
If an injector connector is disconnected for more than 46 seconds while the engine runs, the PCM will determine
that the cylinder is misfiring and cut fuel supply. So be careful not to exceed 46 seconds. But the engine runs
normally in 10 seconds after turning the ignition key off.

COMPONENT INSPECTION
1.Connect a scantool on Diagnoisis Link Connector (DLC).
2. Start engine and check output voltages of TPS 1 and 2 at C.T and W.O.T.
Condition Output Voltage (V)
TPS 1 TPS 2
C.T 0.25 ~ 0.9V Min. 4.0V
W.O.T Min. 4.0V 0.25 ~ 0.9V
3. Turn ignition switch OFF and disconnect the scantool from the DLC.
4. Disconnect ETC module connector and measure resistance between ETC module terminals 4 and 1 (TPS 1).
5. Measure resistance between ETC module terminals 7 and 6 (TPS 2).
Specification: Refer to SPECIFICATION.
ETC MOTOR
1.Disconnect ETC module connector and measure resistance between ETC module terminals 5 and 8.
