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:Warning lightLoss of engine power, no accelerationStalls or shuts offReduced brakingFuel smellGauge or instrument faultLeakMisfire or rough idle

Record by record

7 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 did not fix it5

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.

  1. Manufacturer communication2000–2006 GMC YUKON XL ・ 2017-08-15

    Service Engine Soon Lamp and P0442 Diagnostic Information

    1. 1Fault

      • The service engine soon lamp (MIL) is on with DTC P0442, but no leak can be verified with the system test in the service information.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. Connect the scan tool and command the EVAP system closed.
      2. Start the engine and watch the fuel tank pressure sensor value for about two minutes.
      3. If the tank pressure sensor value changes (shows vacuum), remove the purge solenoid and pressurize its fuel tank side with the GE 41413-A / J 41413-A tester.
      4. If the sensor 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.
      5. With the EVAP system closed, pressurize through the CH 48096 adaptor and watch the pressure/vacuum gauge for at least 5 minutes until the system is fully stable, then add smoke.

    3. 3Correction

      Repair

      • Add smoke and let the pressure stabilize; if smoke passes through the purge solenoid, replace the purge solenoid.

      Caution

      • After verifying P0442, do not disturb any fuel system component before testing.
      • EVAP test pressure must not exceed 13 in H2O (0.5 PSI (= 3.45 kPa)); more can make components perform inaccurately and lead to misdiagnosis.

    From the manufacturer’s document

    • Applies to：Applies to 2015 and prior passenger cars and trucks.
    • Condition：The service engine soon lamp (MIL) is on with DTC P0442, but no leak can be verified with the system test in the service information.
    • Caution：After verifying P0442, do not disturb any fuel system component before testing.
    • Confirm：Connect the scan tool and command the EVAP system closed.
    • Confirm：Start the engine and watch the fuel tank pressure sensor value for about two minutes.
    • Confirm：If the tank pressure sensor value changes (shows vacuum), remove the purge solenoid and pressurize its fuel tank side with the GE 41413-A / J 41413-A tester.
    • Repair：Add smoke and let the pressure stabilize; if smoke passes through the purge solenoid, replace the purge solenoid.
    • Confirm：If the sensor 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.
    • Confirm：With the EVAP system closed, pressurize through the CH 48096 adaptor and watch the pressure/vacuum gauge for at least 5 minutes until the system is fully stable, then add smoke.
    • Confirm：Check the canister vent solenoid filter or fresh-air line for smoke; an intermittent vent solenoid fault may show up when the vent solenoid is cycled and the test repeated.
    • Confirm：If smoke finds nothing, the leak may exist only under vacuum: use the scan tool Purge/Seal function to pull a vacuum on the EVAP system and watch the FTP sensor parameter for vacuum decay.
    • Caution：EVAP test pressure must not exceed 13 in H2O (0.5 PSI (= 3.45 kPa)); more can make components perform inaccurately and lead to misdiagnosis.

    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.
