What does code P04CE mean?

Q: What does code P04CE mean?

EGR Temperature Sensor C Circuit. P04CE indicates that the powertrain control module has detected an abnormal signal from the exhaust gas recirculation temperature sensor on circuit C, which is typically the sensor located after the EGR cooler. The computer compares the sensor voltage against expected values and flags this code when the signal falls outside the valid range for a calibrated period.
