We just bought a used car. The check engine light came on. It is the EGR value. Can it be cleaned?
Can the EGR valve just be cleaned? on 2000 Toyota Camry
It would be best to have your local shop perform inspection and repairs to EGR system. The use of special tools and equipment is required to inspect and test EGR valve, EGR Vacuum Switching valve, EGR Vacuum Modulator and Vacuum signal to components. When performing EGR system test, it may be necessary to monitor engine RPM by using an Automotive scan tool and to inspect for diagnostic trouble codes.
