Our 2015 6.7 F450 CCLB has had a intermittent CEL with a stored P132b. I did some searching and found it to be a fairly common issue on the 6.0/6.4 motors but nothing on the 6.7's. The driver didn't complain of a loss of power. After reading up I found this explanation "The DTC sets when the difference between the actual manifold absolute pressure (MAP) value and the desired (MAP) value is greater than a calibrated threshold when the monitor runs at engine idle". We have another 2015 F450 with the 6.7 so I swapped the map sensors and haven't had the light come on in either truck. This is an intermittent issue and I know it's only a matter of time until the light comes back on in one of the trucks. If it comes back on the original truck, what else should I be looking at?

I’ve seen this a few times with cab chassis trucks, each time I’ve replaced the turbo with no codes returning. Seems like the vanes stick inside or something, and they aren’t simple turbos to just clean like the 6.0s are.
