The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Common on this vehicle:Gauge or instrument faultLeakStalls or shuts offWarning lightCorrosion or rustMisfire or rough idleDoes not startSmoke or fire

Record by record

24 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

How it is said to have ended

  • says it came back1
  • result not stated1

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

      Repair

      1. Dealers inspect the fuel rail crossover tube and replace the retainer screws if necessary.
      2. Hold the fuel crossover tube retainer to the bracket on the fuel rail with locking pliers, using enough force to keep the retainer from moving without damaging any parts.

      Caution

      • The GM bulletin lists Tahoe and Yukon models because Canadian vehicles are included in the bulletin.
    Read the sentences of the record
    Cause
    On certain vehicles, the fuel rail crossover tube retainer screws were not manufactured to specifications and may break. If a tube retainer screw breaks, fuel could leak from the fuel rail crossover joint, the engine may stall and, if an ignition source were present, an engine compartment fire could occur. Correction: Dealers will inspect the fuel rail crossover tube assembly and, if necessary, replace the two tube retainer screws.

    EVAP System Leak Diagnosis for MIL with DTCs P0442/P0455

    1. 1Fault

      • The MIL is on and the ECM has P0442 (EVAP small leak detected) and/or P0455 (EVAP large leak detected).

    2. 2Finding the cause

      Possible causes

      • P0455 sets for a large leak or purge blockage: an unseated tube connection, a damaged tube, a stuck open canister vent valve or a stuck closed purge valve.
      • P0442 sets for a small leak, which can come from a stuck open purge valve or stuck open canister vent valve.

      Steps to confirm (in the document’s order)

      1. Inspect all purge connections for proper installation and look for damage or wear along the lines; if damage is seen, confirm with the smoke test.
      2. Some leaks show only under pressure and some only under vacuum, so check both ways.
      3. Cycling the purge and vent solenoids with GDS2 while inspecting may reveal a sticking valve.
      4. Critical connections 1-3: purge tube to purge valve (at intake manifold), purge tube to chassis EVAP line (rear of engine, near transmission), chassis EVAP line to canister.
      5. Critical connections 4-7: fuel tank load line to canister, vent valve line to vent valve, fuel tank load line jumper connection (near fuel tank), and the fuel tank cap closed properly.

    Engine Check Lamp P0442 Evaporative Emissions System Notification

    1. 1Fault

      • The service engine soon lamp (MIL) is on for DTC P0442, but a leak cannot be verified with the system test in the service information.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. With the scan tool, command the EVAP system CLOSED, start the engine and watch the tank pressure sensor value for about two minutes.
      2. If the tank pressure value changes (shows vacuum), remove the purge solenoid and pressurize its fuel tank side with the GE 41413-A / J 41413-A tester.
      3. If the tank pressure value does not change, install the CH-48096 adaptor between the purge line from the canister and the purge solenoid; use no other adaptor or pressurization method.
      4. With the EVAP system CLOSED, pressurize through the adaptor and let the system stabilize, watching the gauge for at least 5 minutes, then add smoke.
      5. Look for smoke or UV trace fluid at the purge solenoid, the engine side, the fuel cap or capless fill door, and the canister vent solenoid filter or fresh-air line.
      1 more points

    3. 3Correction

      Repair

      • If smoke passes through the purge solenoid, replace the purge solenoid.

      Caution

      • After verifying P0442, do not disturb any fuel system component before testing.
      • Test pressure must not exceed 13 in H2O (0.5 PSI (= 3.45 kPa)); more can make components perform inaccurately and lead to misdiagnosis.
      • A large temperature difference between vehicle, shop and tester seriously affects accuracy; let the vehicle adjust to shop temperature first.

    Remedy
    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.
