CANISTER PURGE SOLENOID DIAGNOSTIC CHART

Input Signal:

CHECK ECU VOLTAGE

With ignition "ON," measure voltage between ECU connector terminal (E30) 19 and ground. It should read 10 - 13 Volts.

CHECK PURGE CONTROL SOLENOID

Disconnect purge control solenoid connector and measure resistance between solenoid terminals. It should read 36 Ohms at 20°C (68°F).

CHECK POWER SUPPLY TO PURGE CONTROL SOLENOID

Voltage Test:

1. Turn ignition switch "ON".
2. Measure voltage between solenoid connector and ground as follows:

Connector & terminal: Voltage:
(E6)1-Ground 10 Volts DC minimum
