When it comes to troubleshooting any issues with Jeep vehicles, the P1729 code is one of the most common codes that you’ll come across. This particular code is related to the transmission ratio control circuit, which is responsible for regulating the gear ratio in the car. If the step motor ON/OFF status does not match the TCM requested ON/OFF status for a period of 200 msec, the DTC will set and it takes two consecutive problem identification trips to illuminate the MIL. There are various causes for the Jeep P1729 code, and knowing the source of the issue is important for finding the right solution.
