I've read a few post on this forum and I'm really impressed with all the extensive knowledge. I've been doing mechanic work (on my own vehicles for about 20 years). But with that being said, I don't think I know nearly as much as some of you about the RAM 1500.

I recently purchased a 2008 Dodge RAM 1500 with 4.7L.
I have a question about mass air sensor. When working on an ACURA years ago, in the shop manual, there was a chart used to test the mass air flow sensor. You would test the ohm readings on certain wire connecting to the MAS. And the chart would tell you what the ohm reading was supposed to be at certain temperatures.

How can I find it for the Dodge?

 

Dodge doesn't use a MAF sensor. Intake air and a separate MAP sensor.

 

Thanks for the reply. Do you know of a chart which I spoke of ??

When testing the IAT sensor, what ohms equal ambient air temp ??
