The PACCAR P0335 crankshaft sensor diagnostic manual is the official service guide published by PACCAR for troubleshooting crankshaft speed signal faults on 2013 MX engines compliant with EPA 2013 emissions standards. This document provides mechanics and workshop technicians with step-by-step diagnostic procedures, electrical schematics, and component specifications required to identify and repair P0335 active and inactive fault codes.
Code P0335 indicates a disturbed or missing crankshaft speed signal during engine operation. The PCI ECU (D420) triggers this fault when one or more holes in the flywheel are not detected within a single crankshaft revolution. The diagnostic runs continuously whenever the engine is running and typically requires three drive cycles for recovery once the fault is corrected.

Applies to these models
This PACCAR P0335 crankshaft sensor manual applies to PACCAR MX diesel engines manufactured for 2013 model year trucks meeting EPA 2013 standards. The crankshaft sensor (F552) and related wiring harness work with the PCI electronic control unit (D420) to monitor crankshaft speed and position during starting and continuous engine operation. When the P0335 fault is active, engine torque is reduced and the camshaft sensor (F558) may serve as backup to allow the engine to continue running.
