We have a 05 sentra here with a 1.8L and from time to time the gas pedal will make the car move. Can not get any codes for it it does have a o2 sensor code. The t/b has been replaced and the gas pedle sensor.

i believe it has to be relearned.

I did one for another shop with my master tech or modis I cant remember which

When you say gas pedal doesn't make the car move, do you mean when you press on the pedal the throttle under the hood doesn't move - or do you mean the vehicle has no power and wont move when accelerating? Could be different things depending on your answer.

Have went thought and did the relearn that they talk about on alldata and on my snannor (snap on)

the throttle under hood will not move. For got then it will only do it in gear when in P,N will rev up just fine

Did you replace the t-body and the pedal sensor to try to fix this problem, or did the problem occur after these parts were replaced?

to try to fix this pro...

Also thought then i would say is then it will only do this in gear. It is fine in N/P

I had one of these that had a rub through on one of the wires to the throttle body. Only messed up in gear when then engine moved slightly and caused the short. I scoped the signal and saw the drop-down, so I knew what was happening. Then it was a matter of finding the short.

I'd scope the signals during the failure to see if anything looks wrong.

mmmmmmmmmmmm something is trying to force itself to the surface here. is there any stored codes? if there are any codes stored the relearn will not work. to see if it's an issue like ric said take cable off transmission and see if the pedal fails when you put the shifter in drive. if you can rev it then as it's racing have someone rock engine back and forth and see if it stumbles. if not then put cable back on and unplug neutral safety switch and see what happens. i think i read something about this in a motor magazine or something along those lines where a sensor in the transmission will cause an issue like this.
