P041A Severity
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
An Exhaust Gas Recirculation (EGR) Temperature Sensor is an electrical sensing probe that monitors EGR temperature and transmits the signal to the engine control control module. When the engine control module (PCM) detects an incorrect signal from the EGR Temperature Sensor, the PCM will set code P041A.
