Check Engine Light and Diagnostic Service

A diagnostic service should be performed when you are experiencing drivability issues, reduced fuel economy, have a check engine or service engine soon light illuminated/or flashing. So if you are in need of auto repair in St. George or Washington give us a call today!

When your Check Engine light comes on, a trouble code will be stored in one or more of your vehicle's computers. There are certain conditions (usually 4-5 specific criteria) that have to be met for a trouble code to set, and it is vitally important that the technician who is diagnosing your car checks all of them before he/she makes a repair decision.

The diagnostic trouble code (DTC) is effectively the “tip of the iceberg”. The trouble code takes you to “an area” for further testing to properly determine where the real fault is. The diagnostic fee allows us the time to thoroughly test and accurately determine the real cause of the warning light using the professional test equipment we have invested in.
