1996 Toyota Corolla 1.6l what is the symptoms of a bad EGR Valve Control Solenoid?
The symptoms of a bad EGR Valve Control Solenoid in a 1996 Toyota Corolla 1.6L include rough idling or stalling, a smell of fuel, increased fuel consumption, pinging, tapping, or knocking sounds, failed smog test, and check engine light on . If you are experiencing any of these symptoms, it is recommended to get your vehicle checked by a professional mechanic.
In terms of DIY, you can try cleaning the solenoid valve with throttle body cleaner and then test the solenoid electronically with a 12-volt supply. If that doesn't work, you can replace the EGR valve, vacuum modulator, and VSV (if equipped) and clean out the carbon buildup to the intake from the EGR valve.
Please note that if you decide to drive the car without the EGR valve and the EGR Valve Solenoid working, you can keep cancelling the code. The ECM will try and work things out and compensate. However, it is not recommended to bypass the EGR valve .
