# Service bulletin PIC\-5671\-C A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 10047360 - Published by NHTSA: 2012\-11\-27 - Manufacturer's number: PIC\-5671\-C - Manufacturer's date: 2012\-09\-01 - NHTSA component: FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY; FUEL SYSTEM, OTHER ## NHTSA's summary CHEVROLET/PONTIAC: FUEL TANK COVER ASSEMBLY \(NU6 EMISSION PACKAGE\) CAN NOT BE ORDERED THRU DEALERSHIP DUE TO PARTS \(25815572 AND 25948766\) BEING PLACED ON RETRICTION THRU PRODUCT QUALITY CENTER \(PQC\). MODELS 2007\-2010 COBALT, G5 AND 2007 ION. \*PE ## The document No address for NHTSA's copy can be built for this communication. Ask the dealer for it by the manufacturer's number. ## Components Fuel system, Fuel tank ## Vehicles listed - 2007 to 2010 CHEVROLET COBALT - 2007 to 2010 PONTIAC G5 - 2007 SATURN ION ## Other bulletins for the same vehicles and component - [GCUS\-9\-887](/bulletins/10123491.md), 2017-11-17, Service bulletin: FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY. 14728B \- Special Coverage \(revised Warranty Transaction Section\). Certain 2006 Chevrolet Cobalt, Pontiac Pursuit, Pontiac G4, and Saturn ION vehicles and certain 2007 Chevrolet Cobalt, Pontiac G5, and Saturn ION vehicles and certain 2008 Chevrolet Cobalt and Pontiac G5 vehicles may have a cracked fuel tank inlet control valve. Vehicles that have had a fuel\-tank removal procedure are especially at risk for this condition, as the tank\-removal process can damage the inlet control valve. This condition may cause fuel or fuel vapor to leak from the fuel tank. A vehicle with this condition may display an illuminated Service Engine Soon \(SES\) light, leak fuel onto the ground under the rear of the vehicle between the rear tires during or after fueling, or emit a strong fuel odor from the rear of the vehicle. Dealers are to replace the fuel tank and compatible fill pipe to correct the condition. - [PIT4943D](/bulletins/10114954.md), 2017-08-15, Service bulletin: FUEL SYSTEM, GASOLINE; FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL. 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. - [PI1443](/bulletins/10113593.md), 2017-08-15, Service bulletin: FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY. This preliminary informational bulletin provides technicians with infomation on fuel tank replacement and replacement/reftrofit of the matching fuel fill hose. - [PIC5671D](/bulletins/10113115.md), 2017-08-15, Service bulletin: FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY. This Preliminary Information communication advises the technician that the fuel tank assembly part numbers 25815572 or 25948766 will no longer be on restriction through the General Motors Product Quality Center. Dealer can now order part through the normal Customer Care and Aftersales parts process. - [14728](/bulletins/10089889.md), 2017-01-30, Service bulletin: FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY; EQUIPMENT. 14728 \- SPECIAL COVERAGE.
