P132B results

Just thought I would share some info on my P132B code. I hear this can be a real pita to diagnose. I replaced my ICP and pigtail about a month ago and shortly after got the dreaded P132b code after noticing lack of power on take off, thanks torque app!!.. Thankfully I have a good friend thats a ford diesel mechanic helping out and brought me a different MAP and MAF sensor to throw on because we checked for leaks briefly and he didn't think it was that. Well the code went away so then I switched back my MAP sensor and bam, code was back. Also we checked the hose and nipple and they were clear and there wasn't a code thrown for the MAP sensor but he said it could still not be reading right. So I bought a new sensor and put my MAF back on and looks like that was it. Sure helps to have friends that drive the same awesome trucks that we drive!! Maybe this will help someone else out down the road..

So did your code always pop right up? I get it only occasionally, and it seems somewhat laggy at low RPM.

KA5 CHECK THE TURBOCHARGER OPERATION BACK PRESSURE

Key ON, engine running.
Using the gauge bar, access the exhaust pressure sensor port.
Access the PCM and monitor the, EGR DC, RPM and VGTDC PIDs.
Access the PCM and control the EGR DC, RPM, and VGTDC PIDs.
Increase the commanded engine speed to 1,200 RPM using output state control. The calibration may limit the actual RPM between 1,150 and 1,200 RPM.

Record the exhaust pressure from the gauge bar.
Increase the VGT duty cycle to 85%.
Record the exhaust pressure from the gauge bar.
Decrease the VGT duty cycle to 0%.
Record the exhaust pressure from the gauge bar.

Is the exhaust pressure gauge reading below 5 kPa (0.73 psi) at 0% VGT duty cycle and above 50 kPa (7.3 psi) at 85% VGT duty cycle?
