There is a sensor that screws into my intake manifold, whats is it called, and whats it purpose, i had a prong to break off of it, and was wondering if i could put the same sensor from a 92 b2600i in it, the truck i have is a 1990 B2600i. Email me or reply back if any help. Thanks

 

Does the sensor that you are talking about screw into the intake manifold at the very front and has ( or had ) two metal prongs protruding from it where the connector plugged in? If so then that is called an intake air thermosensor and is used to tell the engine computer what the temperature of the incoming air is. If your truck has a build date of january 1, 1990 or later then any later model year sensor will fit. If built before that date then will need to find older model year. The build date should be on a sticker on the drivers door jam near the door latch striker.
