CHECK ENGINE LIGHT ON
A flashing check engine light is typically indicative of a serious problem affecting your vehicle’s ignition, fuel or emission systems. If your check engine light is on or flashing, it’s time to come to AutoImports of Denver for a car diagnostic. Our auto service professionals will investigate the check engine code error and troubleshoot the problem. If you delay a car diagnostic or necessary engine repairs, the problems and costs can quickly escalate.
When you bring your car to AutoImports of Denver our experienced Master Mechanics will perform on-board diagnostics and determine why your check engine light (service engine soon) is on or flashing. While it’s impossible to say exactly why a check engine light is on or flashing without being able to examine the vehicle and perform a car diagnostic, possible causes of a steady or flashing check engine light can include:
- Failing oxygen sensor
- A loose gas cap
- Bad spark plug/ignition coil
- Bad spark plug wires
- A problem with your catalytic converter
- Bad mass air flow sensor
- Engine vacuum leak
- EGR valve problem
- Excessive gas consumption or release of air pollutants
The problem you now face is what to do about the check engine light. There are literally thousands of diagnostic trouble codes (DTCs) that the check engine light might refer to. The only way to even get started is to connect a scan tool. Some auto repair shops charge for auto diagnostic services, but some places, such as autoparts stores, offer to scan your vehicle for free. You are probably wondering, “Why should I pay for auto diagnostic service when someone will do it for free?”
Do You Really Want To “Chance” So Called “Free” Auto Diagnostic Services?
The truth is, at best, you’ll get a printout of the DTC and a “guess” as to what the problem might be. It’s an autoparts store, after all, and their business is selling parts, not necessarily fixing cars. At worst, you might buy parts that don’t end up fixing the problem. In the end, you got a “free” auto diagnostic check, but you wasted time and money on unnecessary parts. Where’s the value in that?
