PACCAR MX P0298 is the fault-code chapter of the 2013 PACCAR MX Diagnostic Service Manual covering an oil temperature too high warning level, meaning a real temperature event rather than a sensor circuit fault. The page is a single-sheet reference entry with no published diagnostic tree. Every field beneath the description, from set condition to verification drive cycle, is answered by one line: contact the Engine Support Center.

What the PACCAR MX P0298 chapter covers
- The fault code description as PACCAR words it, for matching a DAVIE readout
- Its separation from the oil temperature circuit codes that sit earlier in the manual
- Confirmation that no set or reset condition is published for the warning level
- Confirmation that no electrical diagram or technical data table is printed
- Confirmation that no possible-cause list or numbered procedure appears
- The single published instruction: contact the Engine Support Center
Diagnostic step sequence and verification
Inside PACCAR MX P0298 the procedure runs as follows. Read this entry next to the oil temperature circuit chapters, which explain that the sensor sits in the oil module before the oil cooler and that engine torque is limited when oil temperature runs too high. Those chapters carry the resistance table from -20°C to 120°C, so a technician can prove the sensor is reporting honestly before treating the warning as a genuine thermal event.
Trucks and engines it applies to
The entry belongs to the EPA 2013 PACCAR MX engine family in Kenworth and Peterbilt trucks, and is retrieved with DAVIE like the rest of the code set. Model programmes and dealer support for these engines are listed on the PACCAR corporate site.
Who needs the PACCAR MX P0298 chapter
Fleets chasing repeat overheating complaints need this page, because it separates a real oil temperature warning from the circuit faults that share the same sensor.
