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 faultNoiseWarning lightCorrosion or rustLeakReduced brakingAir conditioning or heaterVibration or shudder

Record by record

215 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 was fixed2
  • says it held for a while4
  • says it came back4
  • says it did not fix it13
  • result not stated7

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.

      What the documents say to do

      Unwanted ABS activation at low speed (front wheel speed sensor mounting corrosion)

      Confirm

      • The reading should be at least 350 mV AC; if it is less, the wheel speed sensor must be replaced.

      Repair

      1. Dealers remove the sensor, clean its mounting surface on the bearing, apply rust inhibitor and grease, reinstall it and check peak-to-peak output voltage.
      2. The passage heading states that the repair is cleaning the wheel speed sensor mounting surface.

      Caution

      • Do not pry the sensor out of the bore; prying breaks the sensor body off in the bore.

Known issuesSingle-cylinder misfire (P0300-P0308) and/or chirp, squeak or tick at camshaft speed: worn cam lobe / lifter, valve or valve spring1

  1. Manufacturer communication2002–2006 GMC YUKON DENALI ・ 2023-05-06(1 earlier editions of this document folded here)

    Diagnostic tip: valve, lifter or camshaft issue

    1. 1Fault

      • Misfire, chirp, squeak, squeal or tick noise, or MIL illuminated.
      • DTCs P0300 (engine misfire detected) and P0301 through P0308 (misfire detected on cylinders 1 through 8) are listed.

    2. 2Finding the cause

      Possible causes

      • Possible causes: worn camshaft lobe and/or lifter roller, a sticking valve, valve leakage, a broken valve spring, or a collapsed AFM lifter.

      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 the rocker changes the noise, a lifter and/or cam lobe concern on that cylinder is most likely.
      3. Disconnect the coils and injectors on one bank, run the engine with that valve cover removed, back off the rocker arm a couple of turns and listen for a change in the noise.
      4. Measure cam lobe lift at the pushrod side of the rocker arm and compare with other rockers on the same bank; the misfiring or ticking cylinder should have clearly less lift.
      5. A good indicator of a sticking valve is misfires that keep counting on an aggressive deceleration with engine braking.
      1 more points

    3. 3Correction

      Repair

      • If a worn camshaft lobe or lifter roller is found, replace the camshaft and all lifters, and the plastic lifter guide for the affected lifter.

      Caution

      • A damaged cam lobe is easy to overlook through the lifter bores, and unworn lifter rollers do not mean the cam lobes are okay; inspect both carefully.

    2. 2Finding the cause

      Possible causes

      • Monitoring devices and other electronic accessories such as aftermarket cruise control or police speed checking devices (RADAR or LIDAR) may cause one or more of the listed concerns.
      • Many of the problems could come from an open connection on the HSCAN bus; a device that connects to only one CAN + causes bus errors and erratic ECU behavior.

      Steps to confirm (in the document’s order)

      • If normal SI diagnostics find no other root cause, check for a device plugged into the ALDL or Data Link Connector (DLC) for tracking and/or maintenance interval scheduling.

    3. 3Correction

      Repair

      1. If SI diagnostics do not find the source and the device is available, try to duplicate the condition, then remove the device to see whether the condition is eliminated.
      2. If removing the DLC interface device resolves the concern, tell the customer the result and that they should work with the device's supplier for further resolution.

      Caution

    EVAP Leak Diagnostic Service Bulletin (DTCs P0442/P0455)

    1. 1Fault

      • The MIL is illuminated, and DTC P0442 (EVAP small leak detected) and/or P0455 (EVAP large leak detected) may be set in the ECM.

    2. 2Finding the cause

      Possible causes

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

      Steps to confirm (in the document’s order)

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

    MIL Illuminated with Fuel Trim and Oxygen Sensor Codes

    1. 1Fault

      • Customers may comment that the MIL is illuminated.
      • Initial diagnosis may show fuel trim and O2 sensor related codes including P0101, P0137, P0138, P0140, P0141, P0157, P0158, P0160 and P0161.
      • The listed codes also include P0171, P0174, P0420, P0430, P1174 and P1175.

    2. 2Finding the cause

      Possible causes

      • These methods find small leaks around the O2 sensor embossments and slight cracks in an intake plenum or gasket.

      Steps to confirm (in the document’s order)

      1. If normal SI diagnostics do not lead to a resolution and an intake vacuum leak or exhaust leak is suspected, use the GE-52250 Variable Pressure Leak Detector (preferred), the J-41416 ultrasonic leak tester, or possibly soapy water with low pressure air into the tailpipe to find the leak.
      2. For an intake leak, introduce the smoke into the brake booster hose or the oil dipstick tube; soapy water can be sprayed near the gasket, seams and all vacuum nipples.
      3. For an exhaust leak, put the hose with smoke or air into the tailpipe sealed with shop towels, then spray soapy water around seals, seams and bosses.

    Remedy
    This Preliminary information communicates the use of Winter grade fuel during the warm months of 2020 and the potential rivability issues that it can cause. The ongoing Coronavirus (COVID-19) pandemic has caused significant reductions in driving and fuel use.  Due to the surplus of winter grade fuel sitting in storage (pipelines/stations) the EPA is waiving the fuel vapor requirement.  This will extend the use of winter fuel into the summer months. The drivability concerns should not be single events but should be multiple occurrences associated with hot days.

SUSPENSION1

  1. Manufacturer communication2001–2006 GMC YUKON DENALI ・ 2023-12-26(1 earlier editions of this document folded here)

    Suspension Service Communication

    1. 1Fault

      • Condition 1 (2009 or prior vehicles): a Service Suspension System message on the DIC with incorrect rear ride height, and DTC C0696 or C0711 set in the Electronic Suspension Control (ESC) module.
      • Condition 2: a Service Suspension System message on the DIC, possibly with low rear ride height under a heavy payload, and DTC C0711 set in the ESC module.
      • Condition 3: a loose hose hangs down at the left rear; upon inspection the hose may be found damaged or disconnected from the air inlet filter of the auto leveling suspension air compressor.

    2. 2Finding the cause

      Possible causes

      • Condition 1 can be caused by the wiring to the automatic level control (ALC) pressure sensor being shorted to ground.
      • Condition 2 may be caused by an internal fault in the ALC pressure sensor, which can occur when moisture gets into the sensor.

      Steps to confirm (in the document’s order)

      1. The air compressor assembly may have to be removed to see whether the wiring is pinched between the compressor assembly and the frame.
      2. If system pressure at start up is below 10 psi (69 kpa), the system runs the compressor to add air to the shocks as a replenishment cycle.

    3. 3Correction

      Repair

      1. For condition 1, repair any damaged or shorted circuits and reposition the wiring so it is not damaged again when the compressor assembly is installed.
      2. The sensor is no longer serviced separately; to replace it, install a complete air filter, dryer and sensor assembly.
      3. For condition 3, replace the auto leveling compressor air inlet filter and hose assembly (PN 22197160).
