Check resistance between pins 2 and 4. Is resistance between 4.5—5.5 kΩ? YES: Go to Engine Speed Dial Voltage Diagnostics Check. NO: Engine speed dial malfunction. – – –1/1 2 Engine Speed Dial Voltage Check Engine Speed Dial Voltage Connect harness connector to switch panel.
With switch panel connected to harness, measure voltage at pin 2 of connector. Turn the engine speed dial and note voltage. Is engine speed dial voltage within specifications? Specification of Engine Speed Dial Slow Idle 0.3—1.0 V Fast Idle 4.0—4.7 V YES: Go to Sensor Circuit Voltage Check. NO: Engine speed dial malfunction. – – –1/1 Slow Idle 0.3—1.0 V Fast Idle 4.0—4.7 V 3 Sensor Circuit Voltage Check Disconnect connector to switch panel. Check voltage between terminals 2 and 3 of harness connector. Is voltage between 4.5—5.5 volts? NOTE: Key switch: ON YES: Go to Open Circuit Check. NO: Go to Harness Voltage Check. – – –1/1
