Here are some steps which you should follow in order to diagnose this P0C0E fault code:

• Start off by getting the tools needed for this diagnosis. Get your OBD code scanner for your vehicle, and connect it to the diagnostic port. Retrieve all the codes set, even the ones that were set before P0C0E. You will have to troubleshoot them prior to starting diagnosis on this issue. Once you have fixed them, clear the codes and see if it returns.
• If it doesn’t then it was probably these other codes that were the reason for the problem. However, if the code returns then you have to first start by inspecting the wiring and connectors. Repair all the damaged wires, that may be broken, burned, corroded etc. You may also need to replace some parts if they’re beyond repair. Once you have sorted all the wiring issues, go ahead and clear the code and take your vehicle on a test drive to see if the code resets. Of it doesn’t then you may be having an intermittent condition, which may have to worsen before correct diagnosis can be made.
• Upon test drive, if you note that the code has set again, then continue checking the Hydraulic Oil Temperature Sensor, or the TCM. Accordingly, you can opt for repairs or replacements. You may need help in the diagnosis, so don’t worry, you can approach a trained mechanic for it.
