I was wondering if I have to reset the PFC after I adjust the TPS. Car is running really good right now, but I think VTA1 or VTA2 (can't remember right off the top of my head) is slightly off. It's 1.0 or 1.04 or something with the throttle closed. I know it has to be under that. If I adjust the TPS, do I have to reset the PFC? Thanks in advance.

 

Mazda's Standards are:
VTA1: closed 0.10 to 0.70, open 4.2 to 4.6.
VTA2: closed 0.75 to 1.25, open 4.8 to 5.0.

 

Thanks for that. I have that info somewhere. Do you know if the PFC needs to be reset after TPS adjustment?

 

Not really.
