05-06-04-022L2017-08-15. Service bulletin. FUEL SYSTEM, GASOLINE. This informational bulletin provides information on top tier fuels and what brands are available.
PIP53852017-08-15. Service bulletin. FUEL SYSTEM, GASOLINE. This Preliminary Information communication provides information to the technician with the steps to diagnose and repair vehicles that may have Service Engine Soon lamp or reduced engine power message came on and was cleared after cycling the key. Also technician may find a P228C set as current or history, and a prior history of High Pressure Fuel Pump replacement, and the customer has been using E85 fuel. If the Diagnostic Trouble Code is current follow Service Information instruction for the repair. If the code is set in history and there are no current drivability concerns take a large fuel sample and let it sit for a couple of hours looking for contamination. Verify the fuel pressure using a scan tool the actual and desired fuel pressures are very close to the same. If contamination is found in the tank then completely flush the fuel system and add e-10 fuel. Also remove the high pressure fuel pump inlet line from both ends. Using regulated air down to about 60 pounds per square inch or lower, blow through the inlet side of this pipe / hose. Inspect for restriction in the check valve built into this hose. If restricted then replace the pipe run a tank of premium fuel through the vehicle and reevaluate the concern.

Latest revision added model years to the PI with no other changes.
PIP4924C2017-08-15. Service bulletin. FUEL SYSTEM, GASOLINE; FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM; ELECTRICAL SYSTEM:WIRING. This Preliminary Information communication provides information to the technician about vehicles that have Service Engine Soon Malfunction Indicator Lamp on and a misfire. Technician may find Diagnostic Trouble Codes P0201, P0202, P0203, P0204, P0205, P0206, P0261, P0262, P0264, P0265, P0267, P0268, P0270, P0271, P0273, P0274, P0276, P0277, P2146, P2149, P2152, P2155, P216A, and or P216D. Technician will need to inspect the fuel injector wiring harness for rub through or internal wire opens. If this concern is found repair or replace the injector harness as needed.
PIP4964B2017-08-15. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM; FUEL SYSTEM, GASOLINE. This Preliminary Information communication provides information to the technician about vehicles that have a Service Engine Soon Malfunction Indicator Lamp on. Technician will find Diagnostic Trouble Code P2097 or P2099. Technician will need to perform an injector balance or Active Fuel Injector Tester prior to going further. Technician will also need to check for a small leak in the exhaust if published Service Information diagnostics does not lead to a resolution.
PIP5122B2017-08-15. Service bulletin. FUEL SYSTEM, OTHER:DELIVERY:FUEL PUMP; ELECTRICAL SYSTEM. This Preliminary Information communication provides information to the technicians for diagnosing and repairing vehicles that have an issue with a pop noise from the fuel tank area after a cold start or Evaporative Emissions System purge. Technician will be able to use Global Diagnostic System 2 to duplicate the concern by commanding a purge and seal on the Evaporative Emissions System. Replacement of the auxiliary fuel pump module assembly will correct this concern.
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.
