Car wash causing electronic problems?

[lamadoo]

Have you guys experienced any problems after washing your yaris?

I have been using a high pressure hose at the self-car wash and sometimes also spraying on the 'clear coat' they have as well. Afterwards my yaris would experience a lost in acceleration immediately or soon afterwards of driving (Shows up TPS sensor problem in code scanner) or sometimes my car key lock remote won't work but would after a while, perhaps when it dries up.

I've noticed that each time I spray my car the engine bay area becomes pretty wet, especially @ the throttle and air filter area, water would somehow make its way into the engine bay area. I than realized this pattern occurring repetitively and could be why my yaris would get the check engine light on and the loss of acceleration at random times (TPS) and sometimes remote key locking problems.

After changing from 'high pressure hose' to 'low pressure hose' at the car wash and stopped using the 'clear coat' spray , the engine bay looks pretty dry and nice after a good car wash, and i would experience no problems there after. I would also sometimes cover the engine bay with newspapers before washing for fear of getting anything wet.

Has anyone experienced anything similar or is this very abnormal behavior? I always see people using the 'high pressure' hose so thought nothing of it. No more problems as of yet with careful washing now. Looking for your experiences and input thanks guys
