What is the check icon above fuel gauge on 1996 pontiace grand am dashboard?

The check icon above the fuel gauge on a 1996 Pontiac Grand Am dashboard is the service engine soon (SES) light. It is a warning light that indicates that the engine control module (ECM) has detected a problem with the engine or emission control system. When the SES light comes on, it means that the ECM has stored a diagnostic trouble code (DTC) in its memory. The DTC is a code that identifies the specific problem that has been detected.

If the SES light comes on, it is important to have the car diagnosed as soon as possible to determine the cause of the problem. Driving with the SES light on can cause damage to the engine and emission control system.

Here are some possible causes of the SES light coming on:

* Faulty oxygen sensor

* Faulty spark plug or spark plug wire

* Faulty fuel injector

* Faulty ignition coil

* Faulty catalytic converter

* Vacuum leak

* Exhaust leak

* Coolant leak

* Oil leak

If you have a 1996 Pontiac Grand Am and the SES light comes on, it is important to have the car diagnosed as soon as possible to prevent damage to the engine and emission control system.
