2011 RAM 2500 6.7L Cummins - MAP & MAF Sensor Locations?

[556killa]

I started the truck a few days ago and noticed the CEL came on.

The truck has been running an MM3 tuner for several years.

I hooked up my BlueDriver and read the codes.

Unable to delete codes.

I'm trying to locate which sensors are throwing the codes:
P0107 MAP Sensor Circuit Low
P0102 MAF Sensor "A" Circuit Low

The one sensor on the intake has been unplugged since the truck was deleted.

There are two sensors on the air box right after the filter.

I removed and cleaned them, but I still have the code.

The truck is running fine, just reduced power.

Are there other MAP & MAF sensors on the truck other than those 3?

I read about another sensor located by the turbo and another one that threads into the engine on the driver's side.

I appreciate any help you can provide.

Have you changed the filter?

The MAF sensor is located on the air intake tube, the second sensor after the air filter.

The MAP sensor is located on the side of the intake horn, on the firewall side.

Both should be left plugged in before and after tuning.

Attached is the troubleshooting information for your trouble codes.

Yes, I just relaced all the filters less than 2K miles ago.

That's awesome.

Thank you.

I could have sworn the MM3 instructions said to unplug the sensor on the air horn.

I am trying to find that info now.

AK Bob, Water Supply & Corky, thanks for the help!

I was able to trace the problem back to a faulty ASD relay in the fuse box.

Both MAP & MAF sensor fuses were dead.

I ordered a new relay and MAP sensor (it was in bad shape, and I couldn't get it cleaned up).

Put new parts in, deleted codes, and now she's purring like a kitten.

I owe you all a beer if we ever cross paths!

Thanks again!

Glad you got it figured out, bud.

Always a good feeling when she's running how she should.
