West Jordan, UT
I have had p0455 go on and off for the last year or so, usually fixed for a while with a new or tightened gas cap. I took it in at one point and they said there was a crack in my vacuum system somewhere- and it was fused to the carbon canister so they would have to replace both. I did not get the repair because it was too expensive at the time. Now I have this new p1140 code that is for the intake valve timing sensor. The person at autozone told me the codes were probably connected to the same problem. Can someone maybe tell me what this could be? are they connected? can someone give me an estimate on a repair before I take it in?
The front driver-side wheel rumbles loudly when going between 35 and 45 MPH. There is a speed-dependant audible click when going less than 10 MPH. The noise seems to be worse when I let off the gas, but it may just be that it isn't poluted by engine noise. I have no problems braking or turning. We got new tires about 6 months ago, but I seem to remember this starting shortly before then. It has been getting worse. My pathfinder is a V6 4WD. Thanks!
