Component Code 1925SUBJECT: System Malfunctions Related To The Injection Actuation Pressure Sensors In Excavators, Wheel Loaders, Engines, Track-Type Tractors and Track Loaders
PROBLEM:
The Injection Actuation Pressure (IAP) sensors are being replaced on machine applications with C7/3126 engines. Some C9 engine models are also affected. The system event code 164-11 or 164-02 leads the technician to replace the sensor. Many of these sensors are no fault found. The result of these failures is loss of production due to unscheduled downtime.
SOLUTION:
Follow current troubleshooting guidelines for highway trucks to troubleshoot the part causing the failure. This will aid the technician in finding the correct part causing the failure. Report any troubleshooting guidelines errors using the feedback function in the Service Information System (SIS Web).
