Recently I was figuring out a sudden lag in lower rpms and came to know that my TPS was configured to absolute Zero instead of 0.5V. I adjusted it to 0.49 V and it became 4.5 at WOT.

Now it wont let me un park the car. I tried reset by battery then re-learn but nothing works. Anything above 0.39 v it wont allow me and gear shifting gets delayed.

Any hints where to look?


Other than that Brake switch is tested and is working fine

Car is 03 accord

 

The reason is it not letting you shift out of Park, is due to your adjustment to the TPS.

The voltage needs to be at less than .5 volts (this essentially tells the PCM the accelerator pedal is not depressed and the throttle is closed). If it is at a higher voltage, the PCM thinks the accelerator is depressed and the throttle is open and prevents the shift lock solenoid from energizing (you won’t be able to shift out of Park).

 

But even if i adjust it to 0.42 V even then it wont allow me to. My volt meter is correct i have two of them. Any solution?
