Symptoms of a Bad or Failing Air Pump Check Valve1. Exhaust fume odorOne of the first and most common symptoms of a bad or failing check valve is an exhaust fume odor. The odor is a result of exhaust leaking either from the valve housing, or through the actual check valve back into the secondary air injection system. The odor may become most noticeable at idle speeds. Any sort of odor indicates an exhaust leak, which compromises emissions.2. Failed emissions testMany states require their road-going vehicles to pass an emissions test in order for the vehicle to be legally operated. If the air pump check valve fails, it can significantly impact the tailpipe emissions of a vehicle. The air pump check valve works to reduce hydrocarbon and carbon monoxide emissions of a vehicle, so when it fails, the levels of these two pollutants will increase.3. Check Engine Light is OnAnother common symptom of a failed air pump check valve is the Check Engine Light coming on. When a problem is detected by the vehicle's computer, it will set off a code and activate the Check Engine Light. Having the vehicle scanned for trouble codes can reveal if there may be a problem with the air pump check valve that needs to be addressed.
