Diagnostic ProcedureNCEC0565
1 CHECK INPUT SIGNAL CIRCUIT
1. Turn ignition switch ªOFFº.
2. Disconnect ECM harness connector and TCM harness connector. Refer to A/T section for TCM location.
3. Check harness continuity between ECM terminal 91 and TCM terminal 15. Refer to wiring diagram.
4. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 2.
NG©Repair open circuit or short to ground or short to power in harness or connectors.

Component DescriptionNCEC0424When the gear position is ªPº (CVT models only) or ªNº, park/
neutral position (PNP) switch is ªONº.
ECM detects the park/neutral position when continuity with ground
exists.

With CONSULT-II
1) Turn ignition switch ªONº.
2) Select ªDATA MONITORº mode with CONSULT-II.
3) Start engine and warm it up to normal operating temperature.
4) Maintain the following conditions for at least 50 consecutive
seconds.

5) If 1st trip DTC is detected, go to ªDiagnostic Procedureº, EC-
SR-301.
Overall Function CheckNCEC0429Use this procedure to check the overall function of the park/neutral
position switch circuit. During this check, a 1st trip DTC might not
be confirmed.
Without CONSULT-II
1) Turn ignition switch ªONº.
2) Check voltage between ECM terminal 42 (PNP switch signal)
and body ground under the following conditions.
Condition (Gear position) Voltage (V) (Known good data)
ªPº (CVT only) and ªNº position Approx. 0
Except the above position BATTERY VOLTAGE (11 - 14V)
3) If NG, go to ªDiagnostic Procedureº, EC-SR-301.

Component DescriptionNCEC0435The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the injector circuit, the coil in the injector is
energized. The energized coil pulls the needle valve back and
allows fuel to flow through the injector into the intake manifold. The
amount of fuel injected depends upon the injection pulse duration.
Pulse duration is the length of time the injector remains open. The
ECM controls the injection pulse duration based on engine fuel
needs.
