0164-02 Injection Actuation Pressure Signal Erratic (15)
Conditions Which Generate This Code:
The ECM detected one of the following conditions:
- Injection actuation pressure with the engine shutdown
- The actual pressure and the desired pressure are substantially different.
- The change in injection actuation pressure was not consistent with the change in sensor current.
System Response:
Electronic System Response The ECM will indicate an active code and the code will be logged.
Service Tool Display or Lamps Caterpillar Electronic Technician (Cat ET) will display 17.5 MPa (2538 psi) next to "Desired Injection Actuation Pressure" and "Actual Injection Actuation Pressure"on the status screen while the diagnostic code is active. The Check Engine Lamp will illuminate.
Engine Response This code can occur when the engine is off.
Test Step 1. Perform the following diagnostic procedure: Injection Actuation Pressure Sensor - Test
Results:
- OK - STOP
