Thanks! I picked it up yesterday, it still had a CEL, they said it was a stored code, not an active one. They cleared it and said to drive it for a few days. if it comes back on, I 'll have to leave it with them again for further evaluation.Well, as you state, it's a sensor and only gives out a voltage. SC has no bearing on the function of the sensor, so no.
I sold the SC about a month ago....I would have used it though.If you have the s/c installed you can get the codes yourself with the flashpack then let someone here help...
What code are you getting?I have not had my tuner for a month, but I was having a CEL for an o2 sensor intermittently. Last Fri, my sensor went competely and the car has been at the shop since then, probably won't see it until Wed or Thurs. Any way the SC affected this?
yeah i think thats the problem, but that cel is just annoyingthe only prob i've seen before is with bigger exhaust there is a bit more air flow. This changes the speed of the o2 switching. For those of you that dont know the o2 should go rich lean back and forth basically a voltage sweep. With an increase in flow it changes this switching speed. Now there is nothing wrong its just outside factory parameters for how long it should take.
This is for o2upstream only codes. Not cat effiencey. Cat effiency codes are set if the cat is not pulling enough nitrogens of oxide out of the exhaust stream . This is common with high flow cats. THey dont filter as well (i.e. how you get your increased flow)
