Order of inspection
P0669 PCM/ECM/TCM Internal Temperature Sensor Circuit High Low
The P0669 code means the sensor that measures the internal temperature of the computer is giving a signal that is too high. The sensor is built into the circuit board, so diagnosis comes down to ruling out power and ground problems and checking the software.
