Yesterday my wife left the lights on and the battery died on my truck. (aux lights) anyway, we got a jump from the neighbor and the SES light comes on. I tried to reset 3 times and the MAF sensor keeps coming up. (0102) How many MAF sensors are there? I wonder that my bozo neighbor may have unplugged something or fooled with something. I only know of one sensor at the intake. The truck is all stock and has been for about 2 years now. Also is the MAF covered under the powertrain warranty?
