What a check engine light diagnosis involves

Modern cars watch a steady stream of readings from sensors on the engine, fuel and emissions systems. When a reading falls outside its normal range, the engine computer stores a trouble code and turns on the check engine light. The code points to the system that reported the problem, not always to the failed part. A code for a lean fuel mixture, for example, can be caused by a vacuum leak, a dirty sensor, a weak fuel pump or a clogged filter.

That is why reading the code is only the first step. A diagnosis also looks at live sensor data, checks wiring and connectors, and tests the suspected part before anything is replaced. Some causes are as simple as a loose gas cap, while others, such as engine misfires, can damage the catalytic converter if ignored. Florida heat adds to the list, since it is hard on ignition coils, sensors and wiring. You get a plain explanation of the cause and an estimate before any repair.
