Keep in mind that it is very rare for the powertrain control module to be at fault in these cases. It is usually the result of spilling liquid on the upshift/downshift switch. If you have noticed any issues with your vehicle, or if you know that you have the code stored in your vehicle, don’t wait on getting it repaired. Even though it might not be causing you any issues when you are driving now, you don’t want to have the problem get worse. Take your vehicle to a mechanic as quickly as possible to get the repairs the vehicle needs.
