What does P0902 Mean? OBD-II Code Transmission Control Module (TCM) failure is defined as a Clutch Actuator Circuit Low The Clutch locks the transmission and engine together. On some vehicles the clutch is electronically controlled by the Transmission Control Module (TCM). If the clutch does not operate as requested, code P0902 will be set. engine code P0902P0902 fixobd P0902dtc P0902obd code P0902obd2 P0902P0902 car codediagnostic code P0902car code P0902check engine code P0902fehlercode P0902P0902 fiatcodigo P0902codigo falla P0902P0902 kody b??dówcodigo de falla P0902 What are the common causes of P0902 ? A large air leak at or near the number one oxygen sensor would also cause a lean mixture. Faulty IMRC actuator relay (if equipped) Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors. How do you troubleshoot P0902 ? First, you or your technician should reprogram the transmission control module. If this does not solve the issue, you will need to replace the clutch It is important that you either do a fair amount of research or take your vehicle into a professional because you might misdiagnose the problem and spend money on parts or labor that you do not need. Sometimes this code appears on trucks with oversized tires or upgraded performance drivetrains. With an advanced scan tool that is able to read the engine functions, you will need to monitor the duty cycle commanded to the control solenoid. Please know that you will need to monitor the solenoid during engine operation. Using an oscilloscope or graphing multimeter set on the duty cycle scale, connect the negative lead to ground that you trust, and then connect the positive lead to the wire terminal at the solenoid itself. The reading on the multimeter tool should match the commanded duty cycle on your scan tool. If these are opposite, the polarity may be reversed. If this is true, connect the positive lead on the other wire terminal to the solenoid and test again to verify. If the signal detected from the PCM is on all the time, there may be a problem with the PCM. But PCM problems are rare.
