2007 V6 Wrench Light in Snow Ideas?
Here is what I have, and here is what I've done.
I have a 2007 V6, 64,000 miles. For the last two winters I've gotten the wrench light consistently when it snows. Sometimes I get a check engine light that has a generic "cannot calculate torque" code. The first winter I took it to the shop and they recommended replacing the airbox which I did to.
This winter, as the problem occurred more frequently, I went ahead and replaced the throttle position sensor as i hear that is a common failure point which will cause this. The problem still exists.
Yesterday I took apart the airbox and intake, to the MAF sensor. I found the air filter folded over in one corner of the airbox. I suspect this was letting snow get through the filter, and was affecting the MAF air reading, leading to the wrench and/or Check Engine light. I fixed the air filter problem.
My question is, should I be proactive to replace the MAF as well, or should I leave it alone. Would snow/water buildup on the outside of the sensor cause long term damage?
Has anyone dealt with this problem before (I understand its quite common) and found a resolution?
