I am in need of both air intake sensor for my 93 motor. I looked on Rockauto and found a Standard Motor product sensor (AX36) listed for the grid heater control. So I went ahead and ordered one. Well the threads are way to small to fit the intake.

Looks like the AX36 is about 5/8 thread, and the OEM unit is about 3/4-7/8 thread? The number on the OEM unit is 3918461, any one know what the cross reference is for this sensor. Or is it a cummins only part?

 

Here it is, but it says it's for a 94...Mark

 

I got the air intake sensor sorted out today. I went up to my local parts house and we cross referenced the SMP AX36 with the brand they carry. They carry BWD, so the cross references is WT3032.

We looked up a picture in the catalog and it appeared to be correct. It also only listed it for 94-98 Dodge rams, no reference to 91-93. Anyway they brought it in for me and it was the right piece.

We looked through the catalog and found a picture of a sensor that matched the one I received. It appears to be an air temperature sensor for A/C systems on mopars from late 80's to late 90's?

Anyway here is a pic of the 3 sensors.
