Abstract
A self-correcting exhaust gas temperature sensor system includes an exhaust gas temperature sensor, a controller and a storage device. The exhaust gas temperature sensor is configured to be disposed in an exhaust manifold of a vehicle. The controller is programmed to determine a reading of the exhaust gas temperature sensor at a predetermined time, determine a comparative temperature value, calculate an offset difference between the comparative temperature value and the reading of the exhaust gas temperature sensor, and based on the offset difference relative of the comparative temperature value, replace an exhaust gas temperature sensor offset value with the offset difference or with a threshold value. The storage device is configured to store the offset difference or the threshold value.
