Test Description

The number below refers to the step number on the diagnostic table.

  1. 2:  If the voltage is varying above and below the specified range, the conditions is not present.
DTC P0130

Step Action Values Yes No
Schematic Reference:  Engine Controls Schematics 
Connector End View Reference: Engine Controls Connector End Views or Engine Control Module (ECM) Connector End Views
1 Did you perform the Diagnostic System Check - Vehicle? - Go to Step 2  Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2 
  1. Start the engine.
  2. Allow the engine to reach operating temperature. Refer to Scan Tool Data List .
  3. Increase the engine speed to 2,000 RPM.
  4. Observe the HO2S 1 voltage parameter with a scan tool.
Is the HO2S 1 voltage parameter varying 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 in Wiring Systems
4
  1. Turn OFF the ignition.
  2. Disconnect the heated oxygen sensor (HO2S) 1.
  3. Turn ON the ignition, with the engine OFF.
  4. Observe the HO2S 1 voltage parameter with a scan tool.
Is the HO2S 1 voltage parameter above the specified value?		 100 mV Go to Step 5  Go to Step 11 
5
  1. Connect a 3-amp fused jumper wire between the high signal circuit of the HO2S 1 harness connector on the engine harness side and a good ground.
  2. Observe the HO2S 1 voltage parameter with a scan tool.
Is the HO2S 1 voltage parameter less than the specified value?		 100 mV Go to Step 6  Go to Step 7 
6
  1. Remove the jumper wire from the previous step.
  2. Connect a 3-amp fused jumper wire between the high signal circuit of the HO2S 1 harness connector on the engine harness side and the low signal circuit of the HO2S 1 harness connector on the engine harness side.
  3. Observe the HO2S 1 voltage parameter with a scan tool.
Is the HO2S 1 voltage parameter less than the specified value?		 100 mV Go to Step 9  Go to Step 8 
7 Test the HO2S 1 high signal circuit for an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 14  Go to Step 10 
8 Test the HO2S 1 low signal circuit for an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 14  Go to Step 10 
9 Test for an intermittent and for a poor connection at the HO2S 1. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 14  Go to Step 12 
10 Test for an intermittent and for a poor connection at the engine control module (ECM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 14  Go to Step 13 
11 Repair the short between the HO2S 1 high signal circuit and the HO2S 1 heater low control circuit.
Did you complete the repair?		 - Go to Step 14  -
12 Replace the HO2S 1. Refer to Heated Oxygen Sensor Replacement - Position 1 .
Did you complete the replacement?		 - Go to Step 14  -
13 Replace the ECM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming.
Did you complete the replacement?		 - Go to Step 14  -
14
  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 15 
15 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 in Vehicle DTC Information System OK
