Diagnosing the P1229 code is not easy. The code means that one of the sensors listed above (See possible causes) is bad or the wires to the sensor are shorted. I suggest starting by inspecting every sensor. Make sure the sensor are not broken, and if possible disconnect every sensor to see if that make any difference or triggers another code.
