Record by record

31 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 while2
  • says it came back4
  • says it did not fix it7
  • result not stated5

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.

Known issuesThrottle body carbon build-up: idle surge, reduced engine power, throttle DTCs (high mileage)1

  1. Manufacturer communication2006 GMC YUKON ・ 2018-01-16

    Engine Control System Update - Idle Surge and Power Mode Issues

    1. 1Fault

      • If enough carbon builds up, an idle surge, deceleration surge, tip-in hesitation, reduced engine power mode, and/or DTCs P0068, P0121, P1516, P2101, P2119 and/or P2176 may be experienced on high mileage vehicles.

    2. 2Finding the cause

      Possible causes

      • As carbon builds up in the throttle body of a high mileage vehicle, the ECM/PCM learns to compensate by increasing the throttle plate angle.

      Steps to confirm (in the document’s order)

      1. If SI diagnosis does not isolate the cause, inspect the throttle body bore and plate for obvious carbon build up.
      2. Depending on the vehicle, the idle learn reset/reset idle learn is normally found on the Tech 2 ECM menu for Module Set Up or Special Functions/TAC System.

    3. 3Correction

      Repair

      1. If carbon is present, follow the Throttle Body Cleaning Procedure in SI to clean the throttle body.
      2. After ensuring that the throttle body bore and plate are clean, perform an idle learn reset/reset idle learn with the Tech 2/GDS and re-evaluate the concern.

      Caution

      • If the throttle body is cleaned without performing an idle learn reset/reset idle learn with the Tech 2, the ECM/PCM may continue to compensate for the previous carbon build up, and the concern may return along with DTCs P0121, P0506 and/or P0507.
      • If the ECM/PCM of a high mileage vehicle is replaced and/or reprogrammed without performing the Throttle/Idle Learn outlined in SI, it may no longer compensate for existing carbon build up in the throttle body.

    From the manufacturer’s document

    • Applies to：The model table lists the GMC Yukon, model years 2006 - 2018, all V8 engines.
    • Condition：If enough carbon builds up, an idle surge, deceleration surge, tip-in hesitation, reduced engine power mode, and/or DTCs P0068, P0121, P1516, P2101, P2119 and/or P2176 may be experienced on high mileage vehicles.

    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.

    3. 3Correction

      Repair

      1. If a water leak is found, repair it as necessary and verify that the repair is effective.
      2. If corrosion or debris is found on the connector terminals, repair as necessary.

      Caution

      • Aftermarket equipment can generate DTC P2138 and/or other DTCs.

    Throttle Position Sensor Cover Replacement

    1. 1Fault

      • The malfunction indicator lamp (MIL) is illuminated with a Reduced Engine Power message displayed.
      • A scan tool may show DTC P2135: Throttle Position (TP) Sensor 1-2 Correlation set as Current or in History.

    2. 2Finding the cause

      Possible causes

      • The condition may be caused by the difference between TP Sensor 1 and TP Sensor 2 exceeding a calibrated value for more than 2 seconds.

      Steps to confirm (in the document’s order)

      1. After installing the new cover, if the scan tool TP Sensor 1 and 2 Agree/Disagree parameter displays Disagree, replace the throttle body assembly.
      2. If DTC P1516, P2101 and/or P2176 are set, replace the throttle body.

    3. 3Correction

      Repair

      1. Clean the throttle body bore and throttle plate with a clean shop towel and GM Top Engine Cleaner, P/N 1052626 (in Canada, P/N 993026), or ACDelco Upper Engine and Fuel Injector Cleaner, P/N 88861803, or an equivalent product.
      2. Remove the old TP sensor cover from the throttle body: grasp the cover, carefully lift it up and separate it from the throttle body.
      3. Tighten the throttle body fasteners to 89 lb in (= 10.1 N·m) (the text prints the metric value as "10 Y").
      4. Reprogram the ECM using the Service Programming System (SPS) with the latest calibration available on TIS2WEB.
      5. Perform the Throttle Learn Reset Procedure.
