1989-95 ENGINE PERFORMANCE
Toyota EGR Function Testing All Models EGR VALVE 1) Disconnect vacuum hose to EGR valve. Using a hand-held vacuum pump, apply vacuum to EGR valve with engine at idle. Engine should run rough or stall. If engine does not run rough or stall, check EGR valve passages for blockage or faulty EGR valve. Clean passages as necessary. If passages are clear, replace EGR valve. 2) Install vacuum gauge to ported vacuum port to EGR. Raise engine RPM. Vacuum should be present. If vacuum is not present, clear vacuum port of blockage. |
