Smog Repair Concord
D&H Enterprises performs State required smog repair and smog inspections for the entire Concord area. We are equipped and have the expertise to perform smog diagnostics and smog repair to all systems and components on those vehicles that are residing, commuting, and passing through Concord.
Today's vehicles are sophisticated, computer integrated machines engineered to reduce smog emissions when in proper operating condition. California State regulations require smog testing every two years on certain model years. Non-passing vehicles must get smog repair in order to pass the emissions tests. In addition, Concord, and the whole of Contra Costa County, is an enhanced smog emissions testing area. This requires the testing of vehicles with specialized smog equipment that can actually simulate on-road driving conditions. D&H Enterprises uses smog testing equipment that includes the state-of-the-art ESP System OneĀ® Bar-97 certified five-gas analyzer equipped with a dynamometer and Delphi Evaporative Emissions Tester.
Our smog testing may reveal some elements within your vehicle that require smog repair.
These may include the following:
-
Ignition timing
- Ignition system
- Vacuum leaks
- Catalytic converter failure
- Air injection system problems
- Engine damage
- Sensor problems
