Service Engine soon Light
Today I took the air box and tubing out of my car to clean it up ... Before I pressure sprayed it ,,I took the Maf sensor off and IAT sensor off ,,,after washing it all down ,,,I put everthing back together ,,but now the servic engine light is on and it wont go off... I thought after driving for awhile it would but it hasn't .... Some one help me with this ??? I have the 3400 sfi motor....

likely you got water in some connector and it's shorting causing a code to come up. Disconnect the electircal connectors and blow compressed air to dry them out if they are wet.
I don't pressure spray my engine bay unless I do it at a good distance as not to force water somewhere it shouldn't be.sigpic

Service engine light
Well really nothing should be wet because,, like I said I totally removed the air induction systm and then removed the IAT sens. and Maf sens laid the Air Box and the ribbed hose on the ground and then press.sprayed them ... I started up the car without the IAT sensor plugged in ,,,could that have turned the light on in the dash ??? Its plugged in now and I took it for a little drive and its still on.....Comment

Yes.Originally posted by bwwelk
The light is still on because the code is stored. You have to erase the code from the ecm. If it is obdII(probably is) you need to use a scanner. ObdI just unhook the battery for a few minutes.
