Code 32, EGR System Error: Notes

ECM controls vacuum being supplied to EGR valve by energizing and de-energizing solenoid. ECM uses information from various engine sensors to determine when EGR is necessary. ECM will monitor engine operating conditions after requesting EGR to determine if exhaust gas flow has entered the intake manifold.

NOTE: Test numbers refer to numbers on diagnostic chart.

Plugged Intake Passage Shut off engine, and remove EGR valve. Plug exhaust side port using a shop rag or suitable plug. Attempt to start engine. If engine runs at a very high idle (up to 3000 RPM is possible) or if engine starts and stalls, EGR intake passage is not plugged. If vehicle starts and idles normally, intake side passage is plugged.
