04-06-04-051D2017-08-15. Service bulletin. FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM. This informational bulletin provides information for maintenance cleaning of the fuel injectors.
PIT5161E2017-08-15. Service bulletin. FUEL SYSTEM, GASOLINE:STORAGE. This Preliminary Information communication provides information to the technician about vehicles that may have a bump feel or clunk noise at a stop or on launch. Dealer should communicate to the customer this condition is a normal operating characteristic of their vehicle. The bump clunk issue may be due to fuel movement in the fuel tank when not completely full. The condition is eliminated after completely filling the fuel tank.
PIT52082017-08-15. Service bulletin. FUEL SYSTEM, OTHER:STORAGE:FUEL GAUGE SYSTEM. This Preliminary Information communication provides information to the technician about vehicles that after refueling the fuel gauge will show empty. Technician will find Diagnostic Trouble Code P2636. Dealer should question the owner if the key or engine is on while refueling. Dealer should the owner to turn the engine and key off, before refueling the vehicle.
PIT4979C2017-08-15. Service bulletin. FUEL SYSTEM, OTHER:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS; FUEL SYSTEM, GASOLINE. This Preliminary Information communication provides information to the technician about vehicles that have a buzz or rattle type noise during light acceleration around 1200-2000 Revolutions per minute. Technician will need to reposition the fuel line and bracket down away from the floor pan.
PIT5161A2017-08-15. Service bulletin. FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY. This Preliminary Information communication provides information to the technician about vehicles that may have a bump feel or clunk noise at a stop or on launch. Dealer should communicate to the customer this condition is a normal operating characteristic of their vehicle. The bump clunk issue may be due to fuel movement in the fuel tank when not completely full. The condition is eliminated after completely filling the fuel tank.
PIP4568P2017-08-15. Service bulletin. ENGINE; FUEL SYSTEM, GASOLINE. This Preliminary Information communication provides information to the technician that some vehicles may have a Service Engine Soon lamp, engine misfire on cylinder 1, 4, 6, or 7 and/or tick noise. Technician will follow service information diagnosis first. If service information diagnosis does not isolate the cause of this concern perform a cylinder deactivation active fuel management system compression test in service information. If the running compression of the misfiring cylinder stays below 25 Pounds per Square Inch regardless of the active fuel management solenoid being commanded on or off, an active fuel management lifter is mechanically collapsed/stuck or unlocking as soon as the engine is started. Replace all active fuel management lifters, and all plastic lifter guides. Also perform the cylinder deactivation active fuel management Valve Lifter Oil Manifold Diagnosis and Testing in Service Information. If it isolates a concern with the Valve Lifter Oil Manifold, replace it and reevaluate the concern. The active fuel management lifters can also be monitored for proper operation by carefully inspecting the cylinder 1, 4, 6, and 7 rockers and valves while cranking or briefly and safely running the engine with the valve covers removed. If the valve or valves of an active fuel management cylinder stop moving while doing this test, the active fuel management lifter is causing the concern. For 2008-2009 Full Size Truck/SUV or a 2007-2009 Chevrolet Tahoe with the Police Package reprogram the Engine Control Module. On the 2008-2009 Pontiac G8, 2010-2011 Camaro, and 2007-2010 Full Size Trucks with active fuel management, also determine if the active fuel management pressure relief valve shield that is listed in the latest version of 10-06-01-008 has ever been installed. On passenger cars with the LS4 engine, determine if the updated oil pan gasket that is listed in the latest version of 11-06-01-007 has been installed.
PIT5208A2017-08-15. Service bulletin. FUEL SYSTEM, OTHER:STORAGE:FUEL GAUGE SYSTEM; FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY. This Preliminary Information communication provides information to the technician about vehicles that after refueling the fuel gauge will show empty. Technician may find Diagnostic Trouble Code P2636 has set. Technician should be advised that the vehicle is being refueled with the engine running or ignition on.
PIT4943C2017-08-15. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; FUEL SYSTEM, GASOLINE; SERVICE BRAKES, HYDRAULIC. This Preliminary Information communication provides information to the technician about vehicles that have a Service Engine Soon Malfunction Indicator Lamp. Technician may find Diagnostic Trouble Code P0442. Technician will need to review Techlink article from May 2013 titled "Using the Evaporative Emissions System Tester" Technician will need to follow these steps to help diagnose the issue. First after the P0442 has been verified do not disturb any of the fuel system components. The technician now can use the scan tool to close the Evaporative Emissions System. If possible change the tank pressure sensor units from inch_H2O to milimeter_Hg for better resolution. Now the vehicle can be stared to monitor the tank pressure sensor output value for approximately two minutes. If the tank pressure sensor value does change, pressurize the fuel tank side of the purge solenoid with the GE 41413-A / J 41413-A and the necessary adaptors. Now add smoke and allow pressure to stabilize for 2 minutes. If smoke is allowed to pass through the purge solenoid, replace the purge solenoid. If the tank pressure sensor value does not change, then install CH-48096 adaptor between the purge line from the canister and the purge solenoid. With the Evaporative Emissions System closed, pressurize the system through the CH-48096 adaptor and allow the system to completely stabilize, by observing the Press / Vac Gauge for a minimum of 5 minutes. Now add smoke to the system with GE 41413-A / J 41413-A after system stabilization. Now inspect the purge solenoid, engine side, fuel cap, canister vent solenoid filter and any line quick connects. When the leak is unable to be located, test under a vacuum condition. his type of leak may be detected by using the scan tool Purge/Seal function to create a vacuum in the Evaporative Emissions System and then observe the FTP sensor parameter for vacuum decay.
PIT5161B2017-08-15. Service bulletin. EQUIPMENT:RECREATIONAL VEHICLE/TRAILER:LPG SYSTEMS:TANK ASSEMBLY; FUEL SYSTEM, GASOLINE. This Preliminary Information communication provides information to the technician about vehicles that may have a bump feel or clunk noise at a stop or on launch. Dealer should communicate to the customer this condition is a normal operating characteristic of their vehicle. The bump clunk issue may be due to fuel movement in the fuel tank when not completely full. The condition is eliminated after completely filling the fuel tank.
