Integrated Electronic EGR Valve
- With ignition off, connect vacuum gauge to EGR valve. EGR valve should not move. If EGR valve moves, ensure vent filter is unrestricted and replace EGR valve (if necessary).
- Turn ignition on and repeat step 1). When applying vacuum, EGR valve should not move. If EGR valve moves, a fault exists in ECM or electrical circuits. If additional testing is required, see appropriate COMPONENT TESTING article in the EMISSION section.
