DTC 34

DIAGNOSIS:
- The EGR solenoid valve is not in function.
- The harness connector between ECM and EGR solenoid valve is in short or open.

TROUBLE SYMPTOM:
- Poor driving performance on low engine speed




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

Connector & terminal / Specified voltage:
(E30) No.18 - Body / 10 V, max.

2. CHECK EGR SOLENOID VALVE.
1. Turn ignition switch to OFF.
2. Disconnect connector from EGR solenoid valve.
3. Measure resistance between connector terminals of EGR solenoid valve.

Terminals / Specified resistance:
No.1 - No.2 / 36 Ohm at 20 °C (68 °F)




3. CHECK POWER SUPPLY TO EGR SOLENOID VALVE.
1. Turn ignition switch to ON.
2. Measure voltage between EGR solenoid valve connector and body.

Connector & terminal / Specified voltage:
(E16) No.2 - Body / 10 V, max.
