Exhaust Gas Recirculation Temperature (EGRT) Sensor
The EGRT12 (exhaust gas recirculation temperature bank 1, sensor 2) sensor measures the exhaust gas temperature after it is cooled by the EGR cooler. The EGRT12 (exhaust gas recirculation temperature bank 1, sensor 2) sensor is used for EGR flow calculation and EGR cooler diagnostics.
