yes the factory set up does shave 2 different oxygen sensors.

Front 2 and driver rear are wide band. passenger rear in short band.

However from what I have experienced this is what causes the P013C code.

Note sure what is dodges reason was for the one short band sensor.

Order 4 of the NTK sensors from Rockauto Part#23159 $26.79
sensors are plug and play for 06-08 hemi

I have them on my 07 now with 40,000 miles zero codes. :coolsmiley:

Truck also runs alot smother now.

Make sure and tighten till washer is crushed. I don't remember the torque off hand. Absolutely do not put any type of anti seize or oil on then. it will ruin the sensors.

so they are in deed 4 wire which are considered short band
I don't remember off hand where i read about the oxygen sensor on the right rear being different. how ever I did find the sheet I wrote down the part numbers on and they are
56029049AA which is LF,LR,RF

56029049AB which is RR

AS for the source I will keep digging in my records to see where I found this.

For the P013c code I don't have any reference to back me up. Just what Ive experienced.
Dodge changed my Oxygen sensors and ECM twice. Lasted for about 6 months then came back again. Dodge wanted to once again change my ECM. Which was now out of warranty. So looking at the voltage of the O2 sensors I noticed the right rear had a shorter band than the rest. The 3 sensors would run in a range from .325-1.0 at the highest. The RR once it went above .750 it would set the P013c code.

thats when I found that the sensor was different from dodge when doing some research. I do have a 2007 Ram with 5.7ezb which is vin code 2 not vin code D.
So maybe it is different due to the MDS system which my truck has from the factory. I have turned it off with the Diablo tuner if that matters.


Installed the NTK sensors and still have zero codes after 40,000 miles.

Just trying to help with what I've experienced.
