PACCAR MX P0219 is the fault-code chapter of the 2013 PACCAR MX Diagnostic Service Manual covering engine speed data that is valid but too high, in other words a recorded engine overspeed event. It is a one-trip Stop Engine lamp code with three drive cycle recovery and an engine protection freeze frame. Engine speed comes from crankshaft sensor F552 and, as backup, from camshaft sensor F558, both feeding PCI ECU D420.

Diagnostic step sequence and verification
Inside PACCAR MX P0219 the procedure runs as follows. This chapter states plainly that the trouble code is informational and no troubleshooting is required. The single listed step is to contact the PACCAR Engine Support Call Center on 1-800-477-0251 if the code appears repeatedly or will not clear. PACCAR also advises interviewing the driver, since the fault is usually inactive by the time a technician plugs in.
Trucks and engines it applies to
The chapter covers EPA 2013 PACCAR MX engines in Kenworth and Peterbilt trucks, where the red Check Engine lamp is enabled above 2300 rpm and disabled once speed falls back below it. Model programmes and dealer support for these engines are listed on the PACCAR corporate site.
Who needs the PACCAR MX P0219 chapter
Fleet managers and warranty staff lean on this chapter as much as technicians do, because it shows the code records an event rather than a circuit failure waiting to be replaced.
