Identify a Faulty Timing Belt Tensioner with the Innova Scan Tool

The Innova Scan Tool quickly retrieves and identifies existing Diagnostic Trouble Codes (DTCs) stored in your vehicle’s computers. With a quick On-Board Diagnostic (OBD2) Scan, you can retrieve existing DTCs, the I/M Status of the vehicle, and any collected Freeze Frame data from these computers. Refer to the Innova Coverage Checker to determine the level of information supported on your particular vehicle by year, make and model. The Innova Scan Tool effectively diagnoses engine timing-related issues where a faulty timing belt tensioner is the primary cause.
