A failed knock sensor causes the Subaru check engine light to come on. The sensor often tests as functioning, but can fail intermittently while the vehicle is being driven. Knock sensor failure is one of the less obvious causes of a check engine light repair for Ann Arbor drivers.
Repair includes a general diagnosis scan, a check for wiring damage or problems, and a knock sensor replacement.
Intermittent problems are difficult to diagnose, even for our Subaru specialist technicians. Solutions for intermittent problems often involve the technician making a decision based on experience and industry service bulletins. The alternative is to wait until the problem becomes absolute when the defective part finally fails. Our service advisors will inform the customer of these repair options.
