Technician may find Diagnostic Trouble Code U1000. Technician will gain access to the engine harness above the fuel rail. After gaining access to the harness unsecure the harness from the retainers. Now the conduit can be opened to gain access to the wires. Technician will need to find the largest gauge red wire and violate with purple wire in the harness in sure these are the largest gauge wires. After finding the correct wires cut the violate with purple wire near the middle of the wiring that is accessible then cut the red 13mm (.50 inch) longer. Technician will need to strip both violate with purple wires sides and then the top red wire. Do not strip the bottom red wire. After the wires are stripped twist the top red wire and violate with purple wire together. Install a DuraSeal splice sleeve part number 19168447 (Blue) or equivalent to the exposed wires, using the EL-38125-10 splice sleeve crimping tool crimp in the number three nest. Technician will need to gently pull the wires to insure there is a good crimp then heat the splice sleeve with a heat gun to 500 to 700 degrees Fahrenheit. The wires will need to be taped up and placed back in the conduit. Reinstall all the parts that were removed to gain access to the harness and retest.

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.
