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 accelerationMisfire or rough idleStalls or shuts offGauge or instrument faultHard start or long crankLeakDoes not start

Record by record

35 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.

Symptom

Component named as the cause

Work done

How it is said to have ended

  • says it held for a while1
  • says it did not fix it3
  • 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.

    Diagnostic tip on valve, lifter or camshaft issues

    1. 1Fault

      • Misfire, chirp, squeak, squeal or tick noise, with the MIL illuminated and DTC P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 and/or P0308 set.

    2. 2Finding the cause

      Possible causes

      • A worn cam lobe on this engine family generally creates a consistent chirp, squeak, squeal or tick at camshaft speed and/or a misfire with a P0300-P0308 DTC.

      Steps to confirm (in the document’s order)

      1. A verified noise is not eliminated by canceling fuel injectors and occurs at camshaft speed (half of crankshaft speed).
      2. If applying pressure to the valve side of a rocker changes the noise, a lifter and/or cam lobe concern on that cylinder is most likely.
      3. Measure cam lobe lift at the push rod side of the rocker arm; it differs from the SI specification but should be similar to the other rockers on the same bank.
      4. A bore scope or pen light helps when inspecting the cam lobes through the lifter bores; a damaged lobe is easy to overlook.
      5. A good indicator of a sticking valve is that misfires continue to count on an aggressive deceleration with engine braking.
      2 more points

    3. 3Correction

      Repair

      1. If a worn camshaft lobe or lifter roller is found, replace the camshaft and all lifters following SI procedures.
      2. If force is needed to tap the valve off its seat, excessive carbon build up exists, which may be repaired by decarbonizing the engine.
    Read the sentences of the record

    From the manufacturer’s document

    • Applies to：GM passenger cars and trucks with V6/V8 pushrod engines, model years 2002 to 2023.
    • Condition：Misfire, chirp, squeak, squeal or tick noise, with the MIL illuminated and DTC P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 and/or P0308 set.

    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.

    IP to Body Harness Connector Repair for MIL and DTC P2138

    1. 1Fault

      • The engine warning lamp comes on intermittently with a message or indicator showing Reduced Engine Power.
      • DTC P2138 (Accelerator Pedal Position (APP) Sensor 1-2 Correlation) is set as current or in history.

    2. 2Finding the cause

      Possible causes

      • Water may have entered the instrument panel (IP) to body harness connector, which carries the APP sensor signals to the ECM/PCM.

      Steps to confirm (in the document’s order)

      1. Verify that no aftermarket equipment is electrically connected to the APP sensor signal or low reference circuits, or to any other ECM/PCM 5V reference or low reference circuit.
      2. Locate the IP to body harness connector, which may be in or around the left hand kick panel area or inside the IP.
      3. Inspect for a water leak in the area, using a water hose if necessary to find the source.
      4. Possible water leak points include the A-pillar seals, the sunroof drain lines (if equipped) and the windshield/cowl sealing.
      5. Inspect the terminals of the IP to body harness connector for corrosion and debris.

    Fuel Module Reservoir Assembly Overheating Recall

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

      Not stated

    Read the sentences of the record
    Cause
    Certain vehicles were built with fuel module reservoir assemblies that contain fuel pump wires and/or connectors that may overheat under certain operating conditions. Fuel pump wires that overheat may become exposed and result in one or more conditions; 1) If the ignition circuit wire is exposed and shorts to ground, the fuel pump fuse will blow, disabling the fuel pump and causing an engine stall or no-start condition. 2) If sufficient heat is conducted to the pass-through connector, a hole in the connector may result, which may cause the Service Engine Soon light to be illuminated during the emission system diagnostics routine. Fuel vapour (and in some limited cases liquid fuel) may leak out of the fuel tank through the hole in the connector body. 3) If the ignition circuit or ground wire is exposed and shorts to the fuel level sender card wires, inaccurate fuel level readings may result. Correction: Dealers will affect repairs.
