Electronic EGR System Test
NOTE:
The engine temperature sensors must be working properly before performing this test.
- With the engine temperature cold and ignition switch off, connect a voltmeter between Gray wire on EGR solenoid and ground. Start engine. Voltage should read less than 1 volt. This reading should be maintained until normal operating temperature is reached and specified time has elapsed as shown in EGR and Throttle Control Specifications table.
- After normal operating temperature is reached and time has elapsed, voltmeter should register charging system voltage. If voltage readings are not obtained as outlined, replace EGR solenoid and repeat test. If the voltmeter indicates charging system voltage prior to elapse of specified time, replace computer.NOTE: If an engine is restarted while still at normal operating temperature, the voltmeter reading should register 1 volt for the specified time, then register charging system voltage.
