After 30k long trouble free miles I’ve got limp mode once again. This time it is unlike the previous. Being that I’m on a ski trip in Colorado and have to head back to SoCal in about ten days, this is troubling.
It was 1degree Fahrenheit in Aspen Colorado when the van started fine in the morning to get some juice from the alternator. Went out and rode came back at 2pm to move it. 18 degrees now. Everything drove fine until I got to a light maybe a mile down the road. Stopped for red. Upon acceleration it revved pretty normally but then didn’t seem to want to upshift. Revved high. Then it did upshift but power loss was apparent. I pulled down the road and cycled the key. No change.
It currently will upshift while driving but it has no boost and it doesn’t seem to respond to me telling it to upshift. I have a OBD2 scanner connected to my phone that shows me everything. No boost. MAP around 69-75. I pulled the MAF sensor and confirmed the actuator arm is moving.
No MIL and no DTC reported on the OBD scanner. Trying to have a friend aid me in swapping sensors but I am under the assumption that if it were a sensor in the intake path it would clear when the key were cycle.
I’m reading through the LHM diagnostic thread but none of the descriptions sound quite like this. Any help is massively appreciated. I’m far from home.
