Code 32, EGR Circuit Error With Linear EGR: Notes
ECM regulates linear EGR valve to control exhaust gas recirculation by providing a ground control for internal pintle (solenoid). Pintle will pull away from its seat when energized. ECM controls linear EGR valve based upon coolant temperature and throttle position.
NOTE:
Test numbers refer to test numbers on diagnostic chart.
- Checks pintle's ability to be commanded to desired position.
- Checks for voltage to linear EGR valve to verify if problem is in ignition feed circuit.
- Checks ECM control circuit by jumpering across harness terminals with a test light and grounding ALDL (DLC) test terminal "B" to command EGR on.
