This document is the 2013 PACCAR MX Diagnostic Service Manual covering the injector solenoid fault P1213 code P1213, published by PACCAR for diagnostic technicians. It provides detailed electrical schematics, component testing procedures, and step-by-step troubleshooting for fuel injector solenoid valve faults affecting cylinder 6 on EPA 2013–compliant MX engines.
The manual addresses current faults on ECU D420 pin A8 where needle control valve current drops below the 4.50 ampere threshold, triggering a one-trip MIL with three-drive-cycle recovery. Comprehensive freeze-frame data is captured for each fault event.
