If the check engine light remains on the instrument panel, you need to check the fault memory in the engine management control unit using appropriate diagnostic equipment. At this stage, it is crucial that the battery charge level is efficient, as the diagnostic tool will detect and report any issues.

Select the make, model, and engine type of the vehicle in question, then read the error codes, which in this case indicate a fault with the intake air temperature sensor. First, clear the fault memory and assess if the same fault reoccurs.
