Good To Know

Q: What are the symptoms of a bad EGR vacuum switch solenoid? A: Common indicators include a rough engine idle, decreased fuel efficiency, and a illuminated Check Engine light displaying EGR-related trouble codes.

Q: Can a failing solenoid cause my vehicle to fail an emissions test? A: Yes, a faulty solenoid prevents the EGR valve from recycling exhaust gases correctly, which increases engine emissions and triggers an automatic test failure.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
