FORD: 2003-2005 Excursion 2003-2007 F-Super Duty 2004-2008 E-350, E-450 Some 2003-2007 F-Super Duty, 2003-2005 Excursions, and 2004-2008 E-350/450 vehicles equipped with a 6.0L diesel engine may exhibit any one, or a combination, of the following concerns: lack of power, white/black smoke or a surge. These concerns may or may not be accompanied by any one, or a combination, of the following diagnostic trouble codes (DTCs): P0238, P0299, P0404, P0478, P2262 and/or P2263. These concerns and/or DTCs could be a result of coking deposits inside the turbocharger. ACTION Follow the Service Procedure steps to correct the condition. SERVICE PROCEDURE Coking deposits inside the turbocharger turbine housing can impede vane response causing high or low instances of exhaust pressure. Unexpected exhaust pressure results can cause over-boost, under-boost, insufficient or excessive exhaust gas recirculation, or unexpected EGR valve position, resulting in these symptoms.

SUBJECT: Cummins 6.7L Diesel Turbocharger – Necessary System Inspections And Tests OVERVIEW: This bulletin involves the inspection and/or test of the Diesel Turbocharger and related emissions system components. The customer may experience a Malfunction Indicator Lamp (MIL) illumination. Additional diagnosis may reveal that the MIL is due to Diagnostic Trouble Code (DTC): P2262 – Turbocharger Boost Pressure Not Detected – Mechanical. DIAGNOSIS: 1. Connect the StarSCAN® to the Diagnostic Link Connector (DLC). 2. Set the parking brake. Start the vehicle engine. 3. From the “Home” screen on the StarSCAN® select: a. “ECU View” button. b. “PCM Powertrain Control Module” button. c. “View DTC’s” button. 4. Record all Diagnostic Trouble Codes (DTC’s) that are present in the PCM. 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 P1451, P2463, or P242F present in the PCM? a. If YES >>> STOP. Refer to Service Bulletin (SB) 11-002-07 (or later bulletin) to address this concern and before proceeding further with this Service Bulletin. In addition to other repairs, SB 11-002-07 may direct the technician to perform a thorough cleaning of Engine and Exhaust Aftertreatment System components. Contact STAR if additional assistance is required. Proceed to the next step ONLY after SB 11-002-07 has been reviewed and/or performed. b. If NO >>> then proceed to the next step. 6. Verify that the PCM is at the latest application software level. 7. Is the PCM at the latest application software level? a. If YES >>> then proceed to the next step. b. If NO >>> then reprogram the PCM to the latest software level. Refer to SB 18-013-08 (or later bulletin). Proceed to the next step ONLY after the PCM has been reprogrammed to the latest software level. 8. Was DTC P2262 present in the PCM?

In Vehicle Servicing The following services may be completed without removal of the engine from the vehicle. • Removal/replacement of cam belt • Water pump removal/replacement • Oil pump servicing • Intake manifold • Rocker covers • Rocker arm assemblies • Cylinder head removal • Camshafts • Turbocharger 2.2L Engine Disassembly Note: Refer to the service manual for the detailed step-by-step disassembly sequence. The following information addresses special steps only. The 1800cc engine stands 499817000 can be used with adapter RH 498457000 and adapter LH 498457100 to support the 2.2L engine. Remove the engine accessories: i.e. drive belts, alternator, air conditioning compressor, and brackets. HLA Handling Use a small screwdriver to remove the HLA from the rocker socket. Do not damage the o-rings of the machined surfaces when removing the HLAs. To check the HLAs for proper operation, squeeze the HLA between your thumb and finger. The HLA should not compress, it should not be spongy. Place an HLA in a clean 12 mm socket. The socket serves as an oil reservoir. Add engine oil to the socket. Use a small allen wrench or paper clip to depress the check ball. Depress and release the HLA plunger while you hold the check ball open. This purges the air from the HLA and fills the HLA with oil. It usually requires only one stroke to fill the HLA. Store the HLAs in engine oil for later reassembly.

Some 2003-2004 F-Super Duty and Excursion vehicles equipped with the 6.0L engine built on or before 9/29/2003 may experience a P006A or P132B Diagnostic Trouble Code (DTC) with a lack of power condition, surge, or turbocharger flutter after performing Field Service Action (FSA) 06E17, or after recalibrating the vehicle with the inferred Exhaust Pressure (EP) strategy. ACTION This procedure is to be used only on vehicles that have received the inferred EP calibration update. There are a variety of reasons why a customer could experience a lacks power condition with the inferred EP calibration. These can include causes a person may not directly see as impacting the condition or codes set. For example; a Mass Air Flow (MAF) / Manifold Air Pressure (MAP) code can be related to a MAF sensor or a MAP sensor problem. However, those codes can be caused by other items such as: intake leaks, exhaust leaks, Exhaust Gas Recirculation (EGR) problems, and aftermarket modifications. Care should be taken to follow the entire procedure outlined below. Skipping a step may lead to being unable to properly diagnose one of these other conditions setting a code. SERVICE PROCEDURE
