This document is a CAT 3406E engine speed signal calibration troubleshooting guide for on-highway truck engines. It covers diagnostic trouble code 0022-13 (FMI 13), which is triggered when a timing calibration has never been performed on a new ECM or when timing is off by more than three degrees. The single-page reference explains conditions, system response, performance effects, and the corrective procedure.

Applicable truck models
This troubleshooting page applies to Caterpillar 3406E, C-10, and C-12 on-highway truck engines. Specific configurations referenced are C-12 Truck Engine 9NS00001-UP, along with serial prefixes 8YS, 5DS, and 1LW. The document is relevant to any vehicle equipped with these engine models where the Engine Control Module (ECM) has flagged DTC 0022-13. The ECM detects that a timing calibration has never been performed or that timing deviation exceeds three degrees, causing the check engine lamp to illuminate and the ECM to revert to default timing. The engine may run rough or produce white smoke from the exhaust until the calibration is completed. For official Caterpillar technical resources, visit Caterpillar Support and Service.
Who needs this CAT 3406E engine speed manual
Fleet mechanics, independent diesel technicians, and workshop owners servicing Caterpillar 3406E, C-10, or C-12 engines will use this guide when a new ECM is installed or when DTC 0022-13 appears. It provides the single required corrective step — performing the Engine Speed/Timing Sensor Calibrate procedure — so the code can be cleared and normal engine timing restored.
