Check engine light after rain/wash Just curious if this has happened to anyone else. Im not sure if its because something is getting wet, but I got the car scanned and it came up with four codes. Three of them were o2 sensor codes and one was a random misfire code. So Im not sure how the car getting wet would throw those codes so any help would be GREATLY appreciated thanks!!! 
The light only comes on after it gets washed or it rains.

When you look at where the pcm is under the hood a lot of water can get into the connector from a high powered car wash. Disconnect your battery and then see if the codes return.
