mine is stock and i have no plans of changing anything,and i only get code 2262.exh brake is working fine.plz let me know how you make out.

 

no new keys, but they made my wife drop her key off so they could reprogram them both at the same time. It's amazing how the truck took 3600 miles to figure out it didnt like its keys, then another 200 to forget where its boost went & let the exhaust brake go nuts...

I'll post up what happens @ *********** tomorrow

 

I find that weird did they actually reprogram the keys or the truck, or the truck to the keys, because I think it says in you owners manual that once a key is programmed it can't be programmed again, i'm quite sure I remember reading that somewhere in the book, but than again It's a big book!! lol

 

You guys with the 2262 problem, did you have the Rev A reflash already?

 

yes my truck has had the revision A flash.and it is a stripped truck so i don't have the key issue.

 

Here's the 2262 diagnostic flow chart. Don't see any TSB's for anything related .



P2262-TURBOCHARGER BOOST PRESSURE NOT DETECTED - MECHANICAL
For a complete wiring diagram Refer to Section 8W.

Theory of Operation
The variable geometry turbocharger (VGT) is electronically activated by the Electronic turbo actuator. The Electronic turbo actuator is a smart device and receives information via the J1939 datalink from the ECM. The Electronic turbo actuator performs its own diagnostics and reports failures back to the ECM using the J1939 datalink. The ECM then decodes the error message and converts it to a fault code. The ECM lights the MIL lamp immediately after the diagnostic runs and fails. The ECM will turn off the MIL lamp immediately after this diagnostic runs and passes in 4 consecutive drive cycles.

When Monitored:
Ignition on.

Set Condition:
The VGT sliding nozzle is slow to move or is unable to move to the fully closed position at initial key-on. The physical limits of the VGT sliding nozzle have been found to be greater than or less than 100%.

Possible Causes
ELECTRONIC TURBO ACTUATOR
TURBOCHARGER


Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)




Diagnostic Test
1. INTERMITTENT CONNECTION

--------------------------------------------------------------------------------

Turn ignition off.
Disconnect the Electronic Turbo actuator harness connector.

note: Check connectors - Clean/repair as necessary.



Are any pins or damage done to the connector?

Yes
Repair/replace harness.
Perform POWERTRAIN VERIFICATION TEST - 6.7L. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

No
Go To 2


2. ELECTRONIC TURBO ACTUATOR

--------------------------------------------------------------------------------

NOTE: It is important to drain engine coolant before Electronic Turbo Actuator removal.


Remove the Electronic Turbo Actuator from the turbocharger.
Inspect Electronic Turbo Actuator for a broken drive gear on the Electronic Turbo Actuator.

Is the VGT actuator drive gear broken/damaged?

Yes
Replace the Electronic Turbo Actuator
Perform POWERTRAIN VERIFICATION TEST - 6.7L. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

No
Go To 3


3. TURBOCHARGER

--------------------------------------------------------------------------------

Inspect the sector gear on the turbocharger for damage or broken teeth.
Move the sector gear lever on the turbocharger bearing housing up and down from stop to stop.
Check for smooth movement between the stops.

NOTE: The actuator lever must move evenly and crisply as it is moved.



Does the nozzle slide evenly from stop to stop and are the gear teeth undamaged?

Yes
Replace the Electronic Turbo Actuator
Perform POWERTRAIN VERIFICATION TEST - 6.7L. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

No
Replace the turbocharger assembly.
Perform POWERTRAIN VERIFICATION TEST - 6.7L. (Refer to 9 - ENGINE - STANDARD PROCEDURE) .

 

The trucks been to dealership twice already for other CEL codes. Each time I've asked them to put the latest & greatest flash on there. The first time (in cocoa beach) I'm pretty sure they did because it quit having the hesitation/surge problem & my MPG/power seemed to increase

The funny thing is, I put the OE airbox back in last night after I pulled hte code.... check engine light is off now & I got 19mpg@65 on the commute into work. Yesterday w/light on I couldnt get hte overhead to read any higher than 13.5....

also, how do I know if a regen burn is in process?

 

The overhead ahould tell you at 100%, then if conditions are right, you can see the percentage dropping. I don't think the 2262 problem will be fixed by a flash. It is purley a problem with the electronic actuator on the VGT turbo. Whether the motor is sticking , or the tube is sticking, one or the other. I would bet there will be a newly designed turbo, or stronger actuator coming soon.

 

How do I get it to show me percentage? It only shows me something like "System OK" but no percentage...

 

The exhaust brake feature will only function when the Exhaust Brake Switch to the ON position. With the switch in the ON Position and the vehicle moving faster then 5 MPH; the exhaust brake will automatically operate when pressure is removed from the accelerator pedal allowing the ECM to see 0% throttle and 0% fuel delivery.

 

VARIABLE GEOMETRY MECHANISM CHECKS - 6.7L



1. Remove turbocharger electronic actuator, refer to Section 11 - EXHAUST SYSTEM - TURBOCHARGER SYSTEM - ELECTRONIC TURBOCHARGER ACTUATOR - REMOVAL.
2. Inspect turbocharger sector gear and bearing housing surface for damage. Replace turbocharger if damaged.

NOTE: Only moderate force should be required to rotate sector gear. Do not use tools of any kind to force sector gear to move.

3. Rotate sector gear clockwise and counterclockwise. Movement should be smooth, without binding and require only moderate force. If sector gear binds or does not move with moderate force, replace turbocharger.

NOTE: Use stepped alignment pin from turbocharger actuator service kit. If service kit is not available, use pin or drill bit of specified size.






4. Rotate turbocharger sector gear counterclockwise (forward). Insert large end of alignment pin (or a 0.187 in. pin or a 3/16 in. drill) through sector gear until it engages hole in turbocharger bearing housing and sector gear will not rotate. If alignment pin does not engage hole in turbocharger bearing housing, variable geometry mechanism is not closing completely. Turbocharger must be replaced.







5. Remove alignment pin from sector gear and rotate sector gear clockwise (rearward) and insert small end of alignment tool (or 0.125 in. pin or a 1/8 in drill.) through sector gear until it engages the alignment hole in turbocharger bearing housing and sector gear will not rotate. If alignment pin does not engage hole in turbocharger bearing housing, variable geometry mechanism is not opening completely. Turbocharger must be replaced.

NOTE: If turbocharger has passed sector gear movement checks, turbocharger is functional. Turbocharger actuator must be replaced. Leave alignment pin in place.

6. Install electronic turbocharger actuator, refer to 11 - EXHAUST SYSTEM - TURBOCHARGER SYSTEM - ELECTRONIC - TURBOCHARGER ACTUATOR - INSTALLATION.

 

The EVIC push buttons are used to operate the different functions of the EVIC system. Pressing and releasing the MENU button (1) will change the mode displayed to one of the Personal Settings. The STEP button (2) is used to make a selection from the Personal Settings displayed at that time. Pressing and releasing the C/T (compass/temperature) button (5) will cause the EVIC to return to the compass/temperature/trip computer display mode from any other mode. From the compass/temperature/trip computer display mode the STEP button (2) is used to scroll through and make selections in the Trip Functions. Pressing and releasing the RESET button (4) resets the trip computer screen displayed at that time.

thx for the info

I called the dealership & told them the codes I pulled & that it went off this morning... they said bring it by tomorrow... will update after dealership visit

 

I spent 5 hours at dealer today,cancelled work and was at thier doorstep in morning.They said they installed newest software,code is gone and getting 15 mpg.

 

What TSB did they install?
