PACCAR MX P0049 is the single-page index entry that the 2013 PACCAR MX Diagnostic Service Manual publishes for “Air Module VGT speed over range”. Unlike the longer chapters in the same manual, this page carries the code number and its description only: in place of the diagnostic detail it prints the instruction to contact the Engine Support Center.

What the PACCAR MX P0049 page contains
The page keeps the standard chapter skeleton used throughout the manual, but the sections under it are left empty because PACCAR handles this code through its support channel rather than a published test sequence. The headings printed on the page are:
- Code number and fault code description
- Fault code information – Please Contact the Engine Support Center
- Description of component(s) and location of component(s)
- Diagnostic condition, set condition and reset condition of fault code
- Electrical diagram(s) and technical data
- Possible causes and additional information
- Diagnostic step-by-step and verification drive cycle
How workshops use this page
Treat it as confirmation of two things: that the code exists in the EPA2013 MX code list, and that its wording is exactly as shown above, which matters when it has to be quoted on a repair order or a warranty claim. Because no set or reset conditions are published, the next step is the support call rather than a bench test, so record the freeze frame data and the other active codes from the diagnostic session before calling. Neighbouring chapters in the same manual do carry full pin-outs and step-by-step tests, and a related code often explains the one with no published procedure. Company background is on the official PACCAR website.
Who needs this PACCAR MX P0049 page
