Tech Tip: Dodge Has A P2767 Code With Transmission In Limp In Mode
If you encounter a Dodge with a P2767 trouble code set, check the wiring between the transmission and the transmission control module. Make sure the #2 signal wire is not open, shorted to ground, or shorted to any other circuit. If the wiring checks OK, raise all four wheels off the ground, start the vehicle and place the shifter in drive. While lab scope testing the #2 signal wire, obtain second gear. When the transmission is in second gear, there should be a 5-volt square wave pattern being produced by the #2 sensor. If not, replace the sensor.
