Hi there: With the recent rains we have had in California, I found an inch of water in the driver's footwell. The cause of the problem was a clogged sunroof drain which I fixed. The water had also caused corrosion in some of the wires under the carpet in the footwell. I redid the wire connections. However, now I have the Check Engine light on. I took the car to the local AAMCO and they read the codes as P0072 and P0074 which means: P0074 Ambient Air Temperature Sensor No signal / Communication Present and P0072 Ambient Air Temperature Sensor Circuit Low Input. I Took the fuse #40 out as mentioned in this thread: http://www.renntech.org/forums/topic/30207-how-toreset-can-bus/ Still not luck. Would disconnecting the battery help? Could the battery be running low? Any other ideas? Thanks! AA
