Neutral Position Switch (M/T)

DIAGNOSIS:
- The neutral position switch signal is abnormal.
- The harness connector between ECM and neutral position switch is in short or open.

TROUBLE SYMPTOM:
- Erroneous idling




1. CHECK INPUT SIGNAL FOR ECM.
1. Turn ignition switch to ON.
2. Measure voltage between ECM and body.

Connector & terminal / Specified voltage:
(E29) No.16 - Body / 10 - 14 V (Neutral position)
0 V (Other positions)




2. CHECK NEUTRAL POSITION SWITCH.
1. Turn ignition switch to OFF.
2. Disconnect connector from transmission harness.
3. Measure resistance between connector Terminals of transmission harness.

Connector & terminal / Specified resistance:
(T2) No.1 - (T2) No.2 / 1 MOhm, min. (Neutral position)
10 Ohm max. (Other positions)




3. CHECK POWER SUPPLY TO NEUTRAL POSITION SWITCH.
1. Turn ignition switch to ON.
2. Measure voltage between neutral position switch connector and body.

Connector & terminal / Specified voltage:
(B14) No.1 - Body / 10 V, min.
