Help with code
Hi all,
Newbie here (to this site anyway). Hoping that someone can tell me if this code is a potential problem. Truck is 05 Duramax with a Banks (Economy / Towing) tuner, exhaust, intake and speed brake. System runs off of the Palm PDA. I have had Mike Loverich at Inglewood Transmission put a stage 3 kit in the transmission and have added an auxiliary radiator (V2 with fan) from Texas Chris in Houston. Set up to tow about 15,000 lbs worth of toy hauler. Everything to run great and after all of the mods The truck looks like it is going to be very reliable. However, during a recent trip to Utah, I had a little episode where the truck ran rough for a short time (20 to 30 seconds) and at very low revs, belched a bunch of black smoke. I turned the engine off and reset the system (key off / on - throttle pedal 5 times etc.) and she started and ran like nothing had ever happened. I've got about 800 miles worth of towing the rig after the incident with no repeat or trouble whatsoever. I noticed the engine light shortly after the incident and checked the code with the PDA. The code came up "P2563 Turbocharger Vane Control Position Sensor Performance". Given the current performance, I've got half a mind to clear the code and move on. But a nagging feeling (and not a whole lot of experience) keeps me from doing it. So any ideas or advice from all you Gurus out there? |

DTC P2563
DTC DESCRIPTOR DTC P2563 Turbocharger Boost Control Position Sensor Performance DIAGNOSTIC FAULT INFORMATION https://www.dieselbombers.com/attach...1&d=1253767071 IMPORTANT: Always perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. See: Diagnostic Trouble Code Tests and Associated Procedures TYPICAL SCAN TOOL DATA TC Vane Position Sensor https://www.dieselbombers.com/attach...1&d=1253767135 CIRCUIT/SYSTEM DESCRIPTION The position of the turbocharger vanes is controlled by the engine control module (ECM). The ECM utilizes a turbocharger vane control solenoid valve and a turbocharger vane position sensor to control the turbocharger vanes. The ECM will vary the boost dependant upon the load requirements of the engine. Movement of the sensor from the closed position to the open position provides the ECM with a signal voltage through the position sensor signal circuit. The vane position sensor uses the following 3 circuits:
CONDITIONS FOR RUNNING THE DTC
The ECM detects that the difference between turbocharger vane position actual and desired is more than 15 percent for more than 5 seconds ACTION TAKEN WHEN THE DTC SETS
IMPORTANT: The DMM and test leads must be calibrated to 0 ohms in order to prevent misdiagnosis. Use the DMM to perform this test. Refer to the DMM User Manual for calibration procedure.

do you get a squeak noise comming from the turbo when you start it up?

Thanks 2500 HeavyDuty - That is a lot of info to digest - no turbocharger squeeks upon start up. Starts, runs and sounds smooth and normal
