While engine trouble codes are somewhat well understood these days, automatic transmission codes are still confusing many out there. One of the reasons for this is the lack of uniformity between different transmission systems, which often makes troubleshooting them somewhat tricky. This is a check engine light code that could potentially make your vehicle difficult, or impossible to drive altogether. The P code means that your transmission control module, the computer tasked with controlling your automatic transmission, has registered a problem with the torque converter clutch circuit. In other words, your torque converter is not functioning normally, and the cause is most likely a mechanical issue of some sort. One positive thing about this particular error is that its causes are usually benign. The torque converter is a crucial piece of any powertrain that uses an automatic transmission. The torque converter works by utilizing transmission fluid to transfer the power from the engine to the transmission. It consists of a pump , a reactor , and a turbine. The pump and turbine look very similar as they both feature metal fins fanned all around their circumference. The main difference between these two components is the orientation of the fins and the components they are attached to.

P is one of the most common transmission trouble codes.

First time i seen it. Working on cars is dangerous, always be careful and be aware of the hazards of working on any vehicle. Log in. Well the car must go back to the rebuild shop so hopefully it will still be on them. If the elbow, then clean the intake manifold. Try a solennoid I've never fixed P with a solenoid but it is definatly possilbe 2. Could that mean that the EGR isn't working properly? The diagnostic problem lies in that there is no way to measure this pressure, but even if you could all you would see is low pressure. Driving over a pothole, or driving on a hot or cold day doesn't change it. This is where the problem usually lies.

The system hasnt finished testing the secondairy air yet so it very well may come back up too but it may not, as ive never had a problem with this either.
