P2563

P2563-TURBOCHARGER BOOST CONTROL POSITION SENSOR PERFORMANCE







Theory of Operation

The Variable Geometry Turbocharger (VGT) is electronically activated by the Electronic Turbo Actuator. The Electronic Turbo Actuator is a smart device that receives information via the CAN BUS from the Engine Control Module (ECM). The Electronic Turbo Actuator performs it's own diagnostics and reports failures back to the ECM using the CAN BUS. The ECM then decodes the error message and converts it to a fault code. This monitor is a two trip fault. The MIL lamp will turn off once the diagnostic runs and passes in four consecutive drive cycles.

- When Monitored:
Key on, at initial start up. One time per key cycle.

- Set Condition:
Actual position not found.
