Conditions for Clearing the MIL/DTC

2006 Pontiac G6 GTP, 2D Coupe, StandardSECTION Conditions for Clearing the MIL/DTC
WARNING: This page is about a different variant/trim than selected.
  • The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
  • A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
  • A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
  • Clear the MIL and the DTC with a scan tool.
DTC P0133

Step Action Values Yes No
Schematic Reference:  Engine Controls Schematics 
Connector End View Reference: Powertrain Control Module (PCM) Connector End Views or Engine Controls Connector End Views
1 Did you perform the Diagnostic System Check - Vehicle? - Go to Step 2  Go to Diagnostic System Check - Vehicle
2
  1. Start the engine.
  2. Allow the engine to idle at operating temperature. Refer to Scan Tool Data List .
  3. Clear the DTC and record the Freeze/Frame Failure Records.
  4. Observe the affected HO2S parameter with a scan tool.
Does the voltage fluctuate rapidly above and below the specified range?		 300-600 mV Go to Step 3  Go to Step 4 
3
  1. Observe the Freeze Frame/Failure Records for this DTC.
  2. Turn OFF the ignition for 30 seconds.
  3. Start the engine.
  4. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records.
Did the DTC fail this ignition?		 - Go to Step 4  Go to Testing for Intermittent Conditions and Poor Connections
4
  1. Turn OFF the ignition.
  2. Disconnect the affected heated oxygen sensor (HO2S) 1.
  3. Connect a 3-amp fused jumper wire between the HO2S 1 high signal circuit on the engine harness side and a good ground.
  4. Turn ON the ignition, with the engine OFF.
  5. Observe the affected HO2S parameter with a scan tool.
Is the voltage less than the specified value?		 15 mV Go to Step 5  Go to Step 6 
5
  1. Remove the jumper wire from the previous step.
  2. Connect a 3-amp fused jumper wire between the high signal circuit and the low signal circuit of the HO2S 1 on the engine harness side.
  3. Observe the affected HO2S parameter with a scan tool.
Is the voltage less than the specified value?		 15 mV Go to Step 8  Go to Step 7 
6 Test the HO2S 1 high signal circuit for an open or high resistance. Refer to Circuit Testing , Wiring Repairs , and Heated Oxygen Sensor (HO2S) Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 13  Go to Step 10 
7 Test the HO2S 1 low signal circuit for an open or high resistance. Refer to Circuit Testing , Wiring Repairs , and Heated Oxygen Sensor (HO2S) Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 13  Go to Step 10 
8 Inspect for the following that may affect the HO2S operation:
Did you find and correct the condition?		 - Go to Step 13  Go to Step 9 
9
NOTE: Refer to Heated Oxygen and Oxygen Sensor Notice .
Test for an intermittent and for a poor connection at the HO2S 1. Refer to Testing for Intermittent Conditions and Poor Connections , Connector Repairs , and Heated Oxygen Sensor (HO2S) Wiring Repairs .Did you find and correct the condition?		 - Go to Step 13  Go to Step 11 
10 Test for an intermittent and for a poor connection at the powertrain control module (PCM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
Did you find and correct the condition?		 - Go to Step 13  Go to Step 12 
11
NOTE: Refer to Heated Oxygen Sensor (HO2S) Resistance Learn Reset Notice .
Replace the HO2S 1. Refer to Heated Oxygen Sensor (HO2S) Replacement Bank 1 Sensor 1 .Did you complete the replacement?		 - Go to Step 13  -
12 Replace the PCM. Refer to Control Module References for replacement, setup, and programming.
Did you complete the replacement?		 - Go to Step 13  -
13
  1. Clear the DTCs with a scan tool.
  2. Turn OFF the ignition for 30 seconds.
  3. Start the engine.
  4. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records.
Did the DTC fail this ignition?		 - Go to Step 2  Go to Step 14 
14 Observe the Capture Info with a scan tool.
Are there any DTCs that have not been diagnosed?		 - Go to Diagnostic Trouble Code (DTC) List - Vehicle System OK

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
