Thread Tools.

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. Then what does the 7EA engine code mean? The 7EA engine code is not a specific trouble code DTC but rather a generic prompt indicating that further information is needed to pinpoint the exact cause of an issue within the engine control system. It may be triggered by a temporary sensor misread or a more complex problem, such as a faulty sensor, wiring harness issues, or even a malfunctioning ECM itself.

Ibro Cehic Updated on June 29, What everyone expects to get when plugging in an OBD2 scanner is a P type fault code, and you will even if you see 7EA first. 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. Once you plug in the scan tool, you will get two options or two submenus to choose from, one for the ECU and one for the TCM. Then, you pick which system you want to diagnose transmission or engine , and as soon as you select one of the two, you will get a fault code readout just like you normally would. But vehicles with two control modules are common; pretty much all cars with an automatic transmission made after have them.
