C7 Engines for Combat and Tactical Vehicles Caterpillar


0032-05 Turbo Wastegate Solenoid current low

Usage:

C7 FML
Conditions Which Generate This Code:

The Engine Control Module (ECM) detects the following conditions:

  • The ECM detects a low current condition (open circuit) in the circuit for the wastegate solenoid for more than 0.12 seconds.

  • Battery voltage is above 9 VDC.

  • Desired current must be more than 0.2 amp.

System Response:

The ECM will log the diagnostic code and the ECM will trigger a snapshot. The check engine lamp will turn on once the diagnostic code has been active for one minute.

Actual boost pressure may be lower than desired boost pressure while this diagnostic code is active.

This diagnostic code indicates a problem with the circuit for the wastegate solenoid.

Test Step 1. Perform the following diagnostic procedure: Wastegate Solenoid - Test

Results:

  • OK - STOP
