The vehicle moves fine, and it will suddenly seize the throttle and the RPMs will be between 1,000 and 2,000 and display AT on the dashboard? Sometimes i have to turn off the car and wait for few minutes or disconnect and reconnect the battery and it will all be fine and when i diagnose with OBD 2 scanner i get U0072 or P0606 or U0101 and i have changed almost all the sensors and throttle body including the PCM, but the problem still occurs.

Hi,

The P0606 indicates where the problem is coming from. This isn't a sensor issue. Instead, the powertrain control module (PCM) has internal damage with a CPU.

I attached information below, but from experience, the repair has always been the replacement of the PCM.

Take a look at the attached pics and let me know if you have questions.

Take care,

joe

In my question, i indicated that i have changed the PCM and TCM. One new observation is that the battery light first comes on before the seizure takes place immediately after and while the seizures takes place, the battery light goes off.
