Mackpro's post in Issues with PTT on CXU 613 Mack Emissions system was marked as the answer
Exit Inducment is only on the 2013 OBD trucks with the 16 pin OBD connector. On the 2010 emission trucks we do the reset and 2 regens and if the engine sees good NOX readings it will unlock the Derate. You can start a regen then unplug the 9 pin Doag adapter and back out of the regen screen . Plug the diag connector back up and go into Test and then Monitor sensor and choose the inlet and outlet box sensors and view the nox readings while the regen continues

Mackpro's post in E7 460 Injector Pop Testing was marked as the answer
4554 psi is the pop pressure for your injectors. You can go to the Mack E-media website and click on Pre-2000 info and the choose 1999 in the year. Hit search and find the tune up manual 5-309. Then choose it and then click view file and it’s free. If any of the manuals in E-media have a “View File” by the manual part numbers they are free to download.

Mackpro's post in 2013 Mack mp8 check engine light was marked as the answer
Crank case pressure sensor. They go bad quite often. There is a newer updated part number. You can watch videos on YouTube on where it’s located. Make sure you search MP8 or Volvo D13. The MP7 and Volvo D11 are in different spot.

Mackpro's post in Questions on split year 2007 MP7 engine? was marked as the answer
The 04’ emission MP7 in the 2007 CTP and CXP ( possibly in other truck models) was very similar to the 2008 and up MP7’s . Main differences are the 04’ emission had Centrimax oil filter, different exhaust manifold/EGR valve and EGR cooler and the EGR mass flow/temp sensor. And best of all , no DPF exhaust filter and of course no DEF. Copper injector cup with no update available for stainless cups and conical injectors. I also think there was no crank case ventilation filter (CCV).

Mackpro's post in 97 ch 355/380 with rebuilt fuel pump was marked as the answer
I assume it’s a VMAC 2 electronic pump. Did you use the A/B timing light to time and install the pump? Some pumps time on #1 and some time on number 6 . There is a rack rod adjustment that can be done but the pump shop should have done that .

I believe I have a MH heating and air conditioning service manual at work. I’ll see if I can locate it and see if it has any thing you might could use

Mackpro's post in speedometer needs to be rest' was marked as the answer
Being a 93 I assume it’s a VMAC 1 electronic engine However in a rare chance It could be a mechanic fuel pump engine. On all VMAC 1,2 and 3 CH/CX the speedometers are all set the same on the dip switches on the back of the speedo head. The tire size, gear ratio, trans tone wheel teeth ( usually 16) and trans top gear ratio are all changeable using the appropriate Mack software or Tech Tool. That’s how you calibrate the speedo. The new replacement speedo heads are different on the dip switches. Have you replaced the speedo head lately?
