I've had this happen now a couple of times. I take the car to the touchless car wash and leave it running while sitting in it. I've had codes for the bank 1 sensor 2 HO2 sensor and replaced it this morning and all seems back to normal. But when I go through the car wash all is fine until the high powered wash starts and it sprays the front of the car. Then it starts running rough. I shut it off, and wait for the wash cycle to finish, then start it back up. It runs fine. The CEL came on and a scan says P0106 (MAP sensor).

I only have problems during the car wash high spray, and only when it sprays into the front grill, and since it doesn't rain much in AZ I can't compare to all wet conditions when the car is running to know if there is more of a problem here.

It's an 04 autostick.

I'd welcome any thoughts and ideas.

Where do I find the MAP sensor to check if the connector is loose or corroded?

Weird.
