Case IH 2672 – Cab Controller, Implement Control Module, ECM, or PCM: Joystick 1 Grip X-Axis Lever Left Negative Position Status (SPN 2672) / Injection Pump Timing Offset (P2672)

SPN 2672 indicates an out-of-range or negative position reading from the primary joystick's X-axis sensor. P2672 indicates that the Engine Control Module (ECM) has detected the diesel injection pump timing is operating outside of its calibrated limits.

• Case IH tractors and heavy equipment utilizing J1939 CAN data links and electronic joystick controls
• Case IH equipment utilizing electronically controlled diesel injection pumps

1. 1

   For P2672 (Injection Pump fault): Connect a diagnostic scan tool to retrieve codes and review live data for ECM timing-signal deviations.

2. 2

   For P2672 (Injection Pump fault): Inspect the wiring harness and connectors at the injection pump actuator for damage, pushed-out pins, poor contact, or corrosion.

3. 3

   For P2672 (Injection Pump fault): Check the mechanical timing (timing belt, chain, or gear) between the injection pump and the engine to ensure nothing has slipped.

4. 4

   For P2672 (Injection Pump fault): Test the crankshaft and camshaft position sensors, as faulty sensors can provide incorrect reference data to the ECM.

5. 5

   For P2672 (Injection Pump fault): Verify that there is not a low or unstable fuel supply or low fuel rail pressure.

1. 1

   Resolve Wiring Faults

   If the visual inspection reveals damaged wiring or corroded connectors at the injection pump timing control solenoid/actuator, repair or replace the affected harness sections.

2. 2

   Correct Mechanical Timing

   If the mechanical timing is found to be slipped or incorrect, realign the timing gears/chain to the manufacturer's exact specifications.

3. 3

   Replace Faulty Sensors

   If the camshaft or crankshaft position sensors are failing to provide accurate timing signals to the ECM, replace them.

4. 4

   Software Calibration

   If wiring, sensors, and mechanical timing are all verified as good, the issue may stem from an outdated software calibration. Reprogram/flash the ECM with the latest OEM software calibration.

5. 5

   Module Replacement

   If the ECM's internal circuitry or flash memory is damaged and will not accept a calibration update, the ECM/PCM must be replaced and programmed to the machine's VIN/Serial Number.
