P041B OBD-II: Exhaust Gas Recirculation Temperature Sensor "B" Circuit
P041B Severity
Will P041B go away on its own?
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.
What causes OBD-II fault code P041B?
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 P041B.
OBD II Fault Code
- OBD II P041B
OBD-II Code Powertrain Control Module (PCM) failure is defined as a Exhaust Gas Recirculation Temperature Sensor "B" Circuit
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 P041B.
Common Problems That Trigger the P041B Code
- EGR temperature sensor failure
- Powertrain Control Module (PCM) failure
