IMRC Valve Position Sensor Output Voltage Check
1. Remove IMRC valve.
2. Check IMRC valve position sensor output voltage as follows.
If faulty condition is found, replace IMRC valve.
a. Set IMRC valve to fully open position.
b. Connect 3 new 1.5 V batteries (1) in series and check that total voltage is 4.5 - 5.0 V.
c. Connect voltmeter (2) and batteries (1) to IMRC valve position sensor as shown in figure.
Measure IMRC valve position sensor output voltage.
If faulty condition is found, replace IMRC valve.
