Well, I waited until 100k before doing Smarty S67me and cali deletes and am now having problems with the exhaust brake.

EB works most of the time but after high rpm shifts 2900-3000, manual trans, the EB will not engage. I don't always get the code and sometimes after a short burst of throttle induced boost is works again. Strange it should start happening with-in a few 1000 miles of doing deletes but I think is not related?

Turbo seems to make full boost even when the EB will not work. I've played around with the Smarty's ability to change VGT settings but not sure if this will help "clean" the turbo or make it worse?

Any suggestions on what to do to help "free" up the slides would be helpful.

 

turbo needs cleaned and or replaced. the slide is getting stuck.

SUBJECT:
MIL Illumination Due to DTC P2262 - Revised Diagnosis and Repair Procedures
OVERVIEW:
This bulletin discusses revised diagnostic and repair procedures for DTC P2262 -
Turbocharger Boost Pressure Not Detected - Mechanical. Recent PCM calibration
updates have improved the robustness to this DTC through updated diagnostic strategies.
As a result, many events which have no adverse affects on drivability, emissions, or
reliability will no longer set the P2262 fault.
MODELS:
2007 - 2009 (DH/D1) Ram Truck (2500/3500)

DISCUSSION:
Malfunction Indicator Lamp (MIL) illumination due to Diagnostic Trouble Code (DTC):
P2262 - Turbocharger Boost Pressure Not Detected - Mechanical.
As a result of recent PCM calibration updates, the proper repair for some P2262 faults is
to just update the calibration, while others will require cleaning or replacing the
09-002-09 REV. A -2-
turbocharger. Scan Tool software update 9.05 (and later) includes a P2262 diagnosis test
for this purpose. This diagnostic test uses Freeze Frame data stored in the PCM and a
dynamic turbocharger response test to determine the correct repair for each truck with
DTC P2262.
The new P2262 diagnosis test must be used prior to performing any of the following:
· Clearing codes.
· Updating the PCM.
· Beginning the turbocharger repair.
The test must be used with the key in the run position with the engine off, and with coolant
temperature between 50ºF and 180ºF. The time required to run this test will vary with the
calibration level of the truck, from a few seconds up to a couple minutes. This is normal
operation for the test.
NOTE: The P2262 diagnosis test MUST NOT be used after the repair is complete, as
this test CANNOT be used to confirm the repair. Test results will be
inaccurate.
If the customer is experiencing MIL illumination due to Diagnostic Trouble Code (DTC):
P2262 - Turbocharger Boost Pressure Not Detected - Mechanical follow the revised
diagnosis and repair procedures below.
DIAGNOSIS:
1. Connect the Scan Tool to the Diagnostic Link Connector (DLC).
2. Turn the ignition key to the ‘RUN’ position, DO NOT start the engine.
3. From the “Vehicle View” screen on the Scan Tool select:
a. “All DTC's” button.
4. Record all Diagnostic Trouble Codes (DTC's) that are present in the PCM.
NOTE: DO NOT erase DTC’s or reprogram the PCM at this point. If P2262 is not
present in the PCM due to clearing the faults or reprogramming the PCM, the
P2262 diagnosis test in Scan Tool will not run.
NOTE: It is IMPORTANT to record (capture) all DTC's present in the PCM prior to
proceeding further with this diagnosis. Procedures later may cause all DTC's
to be erased.
5. Is DTC P2262 present in the PCM?
a. If YES >>> Proceed to Step #6.
b. If NO >>> Then STOP. This bulletin does not apply.
6. Confirm the engine coolant temperature is between 50ºF and 180ºF.
7. Perform the P2262 diagnostic test with wiTECH®, From the “Vehicle View” screen
select:
a. Select “PCM”.
b. Select “Systems Tests”.
c. Select “P2262 Fault Diagnosis Test Start”.
d. Follow on-screen prompts to complete test.
NOTE: If you receive an error message from test, confirm that the Diagnostic Link
Connector and turbocharger actuator harness connections are secure. Also
confirm that engine coolant temperature is between 50ºF and 180ºF, then run
the test again.
-3- 09-002-09 REV. A
8. Based on the outcome of the P2262 diagnosis test, the Scan Tool will provide one of
the following as the proper direction for the appropriate repair. Based on these results,
refer to the detailed service information available in DealerCONNECT >
TechCONNECT under: Service Info and complete the repair as directed;
a. Update PCM Flash Calibration to the latest calibration. No repair required to
the turbocharger.
b. *Clean the Turbocharger.
c. Update PCM Flash Calibration to the latest calibration and Clean the
Turbocharger.
d. Replace the Turbocharger.
e. Update PCM Flash Calibration to the latest calibration and Replace the
Turbocharger.
NOTE: *If results of P2262 diagnosis test result in “Clean the Turbocharger” for a
SECOND time within 5,000 miles, Turbocharger should be replaced.
9. Does the vehicle have other DTC's as recorded in Step #4 above?
a. Yes >>> Follow appropriate diagnosis procedures or TSB related to diagnosis and
repair of each fault.
b. No >>> Repair complete.
NOTE: All other DTC's or symptoms MUST be addressed prior to returning the
vehicle to the customer.
NOTE: When/if replacing Turbocharger, p/n 68048234AA or 68031095AA must NOT
be used on a D1/DH (Pick Up) models. Turbocharger p/n 68048234AA or
68031095AA are to be used on DA/DC/DM (Cab/Chassis) ONLY.

 

Mine did the same thing... I'm not familiar with the Cali delete setup but on my truck it ended up being the gasket in the back block-off plate on my exhaust manifold. I would check there first. Ensure that the bolts haven't backed off and that the gasket is in good shape.Good luck.

 

think my truck would blow up if i shifted at 3000

 

i agree that the turbo itself is bad if you do replace it go bigger if you are going to in the future anyway just my train of thought

 

As stated, sounds like a turbo cleaning or new one is needed. This is why I did not wait until after 100K to delete. I got this one and only code at less than 4K miles, deleted, and been fine since for the last 3 years.

I would think the good news is that now that you are deleted you are not adding to the issue that caused in the first place and may get lucky with a cleaning.
