PIP5163B2017-08-15. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; FUEL SYSTEM, GASOLINE; ENGINE. This Preliminary Information communication provides information to the technician about engine block that have a possible cylinder bore damage, scoring or out of round as the possible cause of engine oil consumption, misfire, cylinder leakage or blow by. Technician will need to inspect the engine for Cylinder damage or scoring, an out of round cylinder bore, Dirt intrusion, and Catalytic Converter failure.
PIT3046G2017-08-15. Service bulletin. FUEL SYSTEM, OTHER:STORAGE:FUEL GAUGE SYSTEM. This Preliminary Information communication provides information to the technician about vehicles that have an inaccurate fuel gauge. Technician should drive the vehicle to duplicate the concern. The fuel gauge will have a tendency to falsely indicate a lower fuel level than what is actually present. The fuel gauge will take a few minutes to show the correct fuel level. On vehicles equipped with an automatic transmission no buffering takes place when the transmission is in park or neutral. This is a normal characteristic and no repairs are necessary. On vehicles equipped with a manual transmission the fuel gauge is buffered in all gears and neutral. There is a timer which starts to count up when the clutch is depressed. When this timer reaches its calibrated value the buffering stops. This is a normal characteristic and no repairs are necessary.
07-06-04-025K2017-08-15. Service bulletin. FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP. This informational bulletin was provides information for the technician of cold start ticking noises in the engine compartment and may be caused by the fuel pump and/or the fuel injectors and no repairs are needed for a normal condition.

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.
PIT4712D2017-08-15. Service bulletin. FUEL SYSTEM, GASOLINE; FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY. This Preliminary Information communication provides information to the technician about vehicles that the fuel gauge does not go to empty and the vehicle runs out of gas, or they may hear a fuel slosh or noise from the fuel tank area when braking or accelerating from a stop. Technician will need to inspect the fuel tank baffle for being loose.
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.
PIT4712E2017-08-15. Service bulletin. FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY; FUEL SYSTEM, GASOLINE. This Preliminary Information communication provides information to the technician about vehicles that the fuel gauge does not go to empty and the vehicle runs out of gas, or they may hear a fuel slosh or noise from the fuel tank area when braking or accelerating from a stop. Technician will need to inspect the fuel tank baffle for being loose.
