So your engine light is on, and when you use a code reader to retrieve the fault code, it shows 7EA. But OBD or other scanners do not have such 3 digit code starting with a number.

In older vehicles, especially those with a manual transmission, as soon as you plug in the OBD scan tool and it initializes, you will get a fault code readout.
