Conditions for Clearing the MIL/DTC

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 P2196

Step	Action	Values	Yes	No
Schematic Reference: Engine Controls Schematics Connector End View Reference: Engine Controls Connector End Views
1	Did you perform the Diagnostic System Check - Engine Controls?	-	Go to Step 2	Go to Diagnostic System Check - Engine Controls
2	Observe the DTC Information with a scan tool. Is DTC P0132 or P0134 also set?	-	Go to Diagnostic Trouble Code (DTC) List	Go to Step 3
3	Start the engine. Allow the engine to reach the normal operating temperature. Operate the engine above 1,200 RPM for 2 minutes. Observe the HO2S 1 voltage parameter with a scan tool. Does the voltage remain above the specified value?	550 mV	Go to Step 5	Go to Step 4
4	Observe the Freeze Frame/Failure Records for this DTC. Turn OFF the ignition for 30 seconds. Start the engine. 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 5	Go to Intermittent Conditions
5	Turn OFF the ignition. Disconnect the heated oxygen sensor (HO2S) 1 sensor. Start the engine. Observe the HO2S 1 parameter with a scan tool. Is the voltage more than the specified value?	500 mV	Go to Step 6	Go to Step 7
6	Test the HO2S 1 high signal circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 12	Go to Step 9
7	Inspect for the following conditions: HO2S wiring for water intrusion. Silicon-contaminated H02S. Exhaust leaks and restrictions including leaks around the HO2S sealing surface. Refer to Symptoms - Engine Exhaust in Engine Exhaust. Rich or leaking fuel injectors-Refer to Fuel Injector Balance Test with Special Tool . High fuel system pressure-Refer to Fuel System Diagnosis . Fuel that is contaminated-Refer to Alcohol/Contaminants-in-Fuel Diagnosis (W/O Special Tool) or Alcohol/Contaminants-in-Fuel Diagnosis (W/Special Tool) . Repair any of the above or similar engine conditions as necessary. Did you find and correct the condition?	-	Go to Step 12	Go to Step 8
8	Test for an intermittent and poor connections at the harness connector of the HO2S 1 sensor. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.	-	Go to Step 12	Go to Step 10
9	Test for an intermittent and poor connection at the engine control module (ECM). Refer to Testing for Intermittent Conditions and Poor Connections and Repairing Connector Terminals in Wiring Systems. Did you find and correct the condition?	-	Go to Step 12	Go to Step 11
10	Replace the HO2S 1. Refer to Heated Oxygen Sensor Replacement - Position 1 . Did you complete the replacement?	-	Go to Step 12	-
11	Replace the ECM. Refer to Engine Control Module (ECM) Replacement . Did you complete the replacement?	-	Go to Step 12	-
12	Clear the DTCs with a scan tool. Turn OFF the ignition for 30 seconds. Start the engine. 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 13
13	Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List	System OK
