WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 1995 GMC Vandura Special, 1995 GMC Vandura, 1995 GMC Suburban, 1995 GMC Rally Camper Special, and 1995 GMC Rally. However, it is still accessible from the selected car via links, so may be relevant.
Control module 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. Control module 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 control module control circuit by jumpering across harness terminals with a test light and energizing EGR valve.
