vvel Tolerance's

hc_416

I wanted to ask if anyone knows what the tolerances from bank one to bank two should be? I am getting almost .75 difference between bank one and bank two. Also is there a reset I could to to get the sensor's to relearn? Thanks for any advice.

What brings up this question? Are you talking about the position sensors on the backside of the VVEL actuator?

Correct, When I was logging my car I noticed that the vvel was off. I was wondering what the tolerances to see if they were in spec.

Ok yeah the sensor is adjustable. You loosen 2 screws and turn the sensor counter-clockwise and clockwise to adjust. (Forgot which direction is which) It is supposed to read .500 + or - 48 if I am not mistaken. .75 is way off so Im not even sure your car would run being that far off. I would talk to your tuner and see if he has made any adjustments to compensate. Does the car idle correctly? Are you getting a P1090 code at all?

That is whats weird it running pretty good, no codes, no weird idle and pulls hard. The only problem we are having is that after about 4600 rpm it will only do 11.2 afr and no more? I was logging some files and noticed a difference in the two and brought it up. I will recheck the logs to day and get back to let you know the full difference. My maf's are maxed out too but not sure it would cause the car to only do 11.2. Any ideas? bad inj, bad throttle body?
