There is no such thing as a "check engine sensor". The check engine light is triggered when the engine control unit (ECU) detects a problem with the vehicle's emissions control system. The ECU is responsible for monitoring various sensors and components in the engine and exhaust system, and if it detects a fault or malfunction, it will illuminate the check engine light to alert the driver.
The check engine light is not associated with a specific sensor but rather indicates a general problem with the emissions system. If the check engine light is illuminated, it is recommended to have the vehicle diagnosed by a qualified mechanic or automotive technician to identify the specific issue and make necessary repairs.
