IF YOU CONFIRM: • DTC P0400 (EGR) or P0402 (EGRC-BPT Valve) is stored in the ECM, and/or • The vehicle exhibits rough running or other drivability incidents, and/or • Difficulty in setting the EGR System Readiness Test (SRT) status to CMPLT. ACTION: Clean the intake manifold EGR ports.SERVICE PROCEDURE 1. Remove the throttle chamber assembly and place it aside. • Refer to the EM section of the appropriate Service Manual (ESM). NOTE: It is not necessary to completely remove the throttle chamber assembly. • Only remove harness connectors, cables, and hoses necessary to allow the throttle chamber assembly to be placed aside. • Throttle chamber coolant hoses do not need to be removed. NOTE: Figure 1 gives a general location of the plugs for the EGR ports, but the plugs are not visible in the photo. 2/4 2. Remove the EGR valve mounting bolts and then move the EGR valve outward about ½ inch (see Figure 2). • This is so you can remove the plug for the “rear most” EGR port. NOTE: You don’t need to completely remove the EGR valve. Rear Most EGR Port. EGR Valve EGR Mounting Bolts Move about ½ inch. Figure 2 3. Remove the plugs for the EGR ports (see Figure 3). Figure 3

FORD: 2005 Mustang 2004-2005 F-150 2005 Expedition, F-250, F-350 This article supersedes TSB 05-15-8 to update the Service Procedure. ISSUE Some vehicles equipped with a 4.6L 3-valve or 5.4L 3-valve engine may exhibit a ticking and/or knocking noise after reaching normal operating temperature. The noise may be described as “ticks”, “taps”, “knocks”, or “thumps”. In some cases the noise may be a normal characteristic of these engines. In other cases the noise may require further investigation. Sorting out and defining the noise as reported by the customer is important to successfully diagnose and/or repair the condition. ACTION Before starting diagnosis, it is critical to determine the specific engine noise the customer is concerned with. The customer should be interviewed to get their detailed perception and description of the noise, and to determine if the noise occurs at idle or above idle speed, and if the engine is cold, hot, or both. Attempt to duplicate the noise, and determine the source of the symptom. Refer to the following Service Procedure to help determine the source of the noise and if a repair is needed. LINCOLN: 2005 Navigator PRE-CHECKS 1. 2. 3.

Customer Concern: Tests/Procedures: Potential Causes: Tech Tips: Loss of engine coolant, and smokes out the tailpipe. No external coolant leaks. 1. If the engine does not appear to be burning the coolant, suspect a leaking Exhaust Gas Recirculation (EGR) cooler. 2. Remove the EGR valve from the intake. Pressurize the cooling system and lift the rear end of the vehicle. Look for any coolant to puddle in the intake where the EGR mounts. If any coolant is seen, replace the EGR cooler. 3. If no leaks are seen with the EGR removed, drain the coolant level down and pressurize the cooling system. Then with a stethoscope and long hose, listen for air in the exhaust or in the intake where the EGR mounts. If present, again replace the EGR cooler. Exhaust Gas Recirculation (EGR) Cooler NOTE: refer to Ford Technical Service Bulletin (TSB) 09-8-3 for tips on addressing cooling system problems. It is generally recommended to also replace the oil cooler heat exchanger if an EGR cooler failure has occurred.

IF YOU CONFIRM The MIL is ON and code P1402 EGR OPEN is stored in the ECM. ACTION • Inspect the EGR valve for metallic debris. See the Service Information section of this bulletin for the specific inspection procedure. • If metallic debris is present, replace the Bank 1 catalyst and EGR valve. SERVICE INFORMATION 1. Remove the EGR valve as per the EM section of the respective ESM. 2. Inspect the EGR valve for metallic flake debris. (see Figures 1 and 2) 3. If metallic debris is present in the EGR valve, remove Bank 1 catalyst (rear of engine) as per EM section of the respective ESM. 4. Inspect both the top and bottom of the catalyst. • Bank 1 Catalyst–viewed from the top. (see Figure 3) 5. If the catalyst has loose material as seen if Figure 3 above, blow out the debris from interior of Bank 1 exhaust manifold. Remove the EGR valve and tube, and then blow out any debris from the EGR valve and tube. 6. Replace the Bank 1 catalyst and EGR valve in the reverse order of removal. 7. Clear stored code P1402 from the ECM memory.
