I want to clean my MAP and MAF sensors. I always thought those were 2 different sensors, forgive me if I’m wrong. Anyone have any tips?

Use an non chlorinated cleaner when cleaning. Geno's garage has good pricing on these sensors compared to the dealer.

A drop in mpg's may be a clue also. From Geno's garage:

Description
If your '07.5-'18, 6.7L Dodge Turbo Diesel truck is experiencing poor engine performance by getting the wrong amount of fuel to the engine, it could be the manifold pressure sensor. You may see black exhaust smoke or the turbo may not be spinning up to full boost as well.

Before you replace the MAP sensor, check the all of the connections and grounds first to see that they are good and clean.

Not bad prices at all. I use Genos for filters and have always been happy with them.

They are 2nd to no one. I'm sure you know about their 10% off all Fleetguard filters in July. That is when I stock up for the year.

I’ll find out soon. I think for how computer controlled these trucks are, it’s just good practise to do them once a year. I’ve noticed my truck ‘not fuelling’ as much which makes me believe it’s not reading all the air it’s getting.

So with only 30K on the truck...

The MAP was black, with some, not a lot, of crusty black soot on it. Cleaned today and noticed a little performance gain. I think I’ll check this at each oil change for the heck of it.

Where is it located ? My truck has 46k on it. Runs good, but Im doing fuel filters this weekend so I may as well clean it if needed.

Sooo my terminology is probably wrong here. The MAF sensor is on your airbox tube held in with 2 bolts. The MAP is on the drivers side of the engine. Look at the intake horn, on the back side of it. It’s held in with 1 torx screw.
