Sentra (Exc. M.P.G.) & 310
- Visually check fuel shut-off system for proper installation of components and for proper routing of vacuum hoses and wires. Connect circuit tester to the function check connector.
- Disconnect fuel shut-off relay. Turn ignition switch "ON". Voltage should be present across Green/Red (Brown on 310) and Black wires with clutch pedal depressed or transmission in neutral. Reconnect fuel shut-off relay.
- Start engine and warm to normal operating temperature. Disconnect anti-dieseling solenoid valve connector or vacuum switch connector. Engine should run rough or stall. If not, replace anti-dieseling solenoid valve.
- Raise front of vehicle high enough so that front wheels are allowed to turn freely. Support with safety stands and block rear wheels.
- Connect voltmeter across Brown and Black terminals at function test connector. With engine running, place transmission in top position. Raise vehicle speed to 50 MPH, then quickly release accelerator.
- If voltmeter reads 0 volts at speeds above 40 MPH (45 MPH on 310) and 12 volts below 40 MPH (45 on 310), fuel shut-off system is operating properly and test is complete. If readings are not correct, continue with individual component testing.
