P006F

P006F-TURBOCHARGER BOOST CONTROL SUPPLY VOLTAGE CIRCUIT HIGH





For a complete wiring diagram refer to the Wiring Information Electrical Diagrams.

Theory of Operation

The Variable Geometry Turbocharger (VGT) is electronically controlled by the Electronic Turbo Actuator. The Electronic Turbo Actuator is a smart device; it communicates information with the ECM over the CAN C BUS. The Electronic Turbo Actuator performs its own internal diagnostics and reports failures back to the ECM. The ECM then decodes the error message and converts it to a fault code. The ECM lights the Malfunction Indicator Lamp (MIL) after the diagnostic runs and fails in two consecutive drive cycles. The ECM will turn off the MIL immediately after this diagnostic runs and passes in 4 consecutive drive cycles.

- When Monitored:
Ignition on.

- Set Condition:
The internal VGT actuator temperature has exceeded 125°C (257°F).





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure

DTC P006F PRESENT
1. Turn Ignition on.
2. With the scan tool, read DTC's

Is P006F active?

Yes

- The VGT actuator internal temperature has exceeded the maximum limit. Verify generator, batteries, Smart Power Relay and TIPM connections are tight and free of dirt/corrosion. This fault code is for information only and will not light the MIL lamp.

No

- Repair complete erase DTC's
