Yep what Cat said. check the Eng. Sensor fuse in the fuse block under the hood (little yellow fuse). if thats not it check the wire harness to the MAF sensor, thats what mine turned out to be. Or it can just be a bad MAF sensor

Re: what would cause this

How do you replace/fix the MAF wiring/harness? I'm getting intermittent P0102's and I've already replaced the MAF and confirmed the Eng. Sensor fuse is OK.

I had a fake low coolant light issue recently too. Maybe I'll try some electrical contact cleaner on the MAF sensor, that appears to have fixed the coolant light.

Would there be any problems with a <2yr old battery which don't show up on a battery/charging test?
