How to Diagnose the Causes of Check Engine and ABS Lights Coming On

If your check engine and ABS lights have come on, it means that your vehicle’s onboard diagnostic system has detected a problem with one or more of its components. The check engine light is a warning light that indicates a malfunction in the engine control system, while the ABS light warns of an issue with the anti-lock braking system. In either case, it is important to diagnose and repair the issue as quickly as possible to ensure safe operation of your vehicle. Common causes for both lights include faulty sensors, electrical wiring problems, or defective components. To properly diagnose and repair the issue, you should take your vehicle to a qualified mechanic who can use specialized diagnostic equipment to identify and fix the problem.

Automobile: Check Engine and ABS Lights On


Common Causes



The most common causes of the check engine and ABS lights coming on in an automobile are a defective oxygen sensor, a malfunctioning mass airflow sensor, or a faulty catalytic converter. Other potential causes include a broken spark plug, a failed fuel injector, or an issue with the exhaust system. In some cases, the cause can be as simple as a loose or missing gas cap.
