Just wondering if anyone can determine or guess why the amigos shows up only when its raining. Grounded? Where to look first? Thanks

 

If it is when or after you drive I'd bet the little o ring around the sensor is letting water in.

 

I would buy a scanner that can read the codes so u aren't guessing at what the problem might be. The icarsoft can do a lot for a a small price.

 

X2. I have the icarsoft i930. Invaluable. Cheap. On Amazon.

But it will only tell you that a sensor is malfunctioning; it won't tell you why.

The hated amigos could also caused by problems other than your sensor though, like low brake fluid, a bad shuttle valve, etc. I was just guessing based on the rain comment.
