- After all, if you sure the engine trouble is finished, the code will be cleared.
The transmission uses hydraulic pressure, controlled by solenoids, which are controlled by the PCM, to shift gears and provide torque converter lockup. The PCM calculates the necessary amount of pressure at any given time to optimize vehicle operation.
A digital volt/ohmmeter may be necessary to compare the voltage reading with the manufacturer's specifications. The mechanic should always clear the code and retest the system after each possible repair, to ensure that they've made the proper diagnosis.
Sometimes P2156 code comes with P215600 code.Diagnosis Of Engine Error OBD Code P2156
It's essential to diagnose this trouble code. Then are some way which a handyperson should follow for diagnosing the problem that started a P2156 trouble code to be stored

It's always good to rule that out.
The coming step is to run a introductory examination of all the electrical circuits, connectors, wiring etc for damages similar as becks, erosion, fraudulent legs etc. All of these will have to be repaired or replaced. After that's sorted, clear the canons and go on a test drive to see if it resets. In case it resets, you'll have to continue your opinion. Depending on your vehicle you may have a vacuum operated selector or a vacuum solenoid if it's electrically actuated. In the case of the former, a hand held vacuum pump will have to be used to testit.The purpose is to see if the internal stopcock is getting turned by the selector, motor or solenoid. In order to do this, a command can be transferred to the system with scanner or by driving the vehicle under the special conditions that will spark the system. While this is passing keep an eye on the checkup tool data for the result.
