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 P0132

Step	Action	Values	Yes	No

1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Start the engine. Allow the engine to idle at operating temperature. Refer to Scan Tool Data List . Clear the DTC and record the Freeze/Frame Failure Records. Observe the HO2S 1 parameter with a scan tool. Is the voltage fluctuating above and below the specified range?	300-600 mV	Go to Step 3	Go to Step 4
3	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 4	Go to Testing for Intermittent Conditions and Poor Connections
4	Turn OFF the ignition. Disconnect the heated oxygen sensor (HO2S) 1. Turn ON the ignition, with the engine OFF. Observe the HO2S 1 parameter with a scan tool. Is the voltage more than the specified value?	500 mV	Go to Step 5	Go to Step 6
5	Test the HO2S 1 high signal circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 8
6	Inspect for the following conditions that may affect the HO2S operation: NOTE: Refer to Silicon Contamination of Heated Oxygen Sensors Notice . HO2S contamination Engine oil consumption-Refer to Oil Consumption Diagnosis . NOTE: Refer to Heated Oxygen and Oxygen Sensor Notice . Chafed, burnt, cut, pinched, or otherwise damaged HO2S wiring Open or high resistance in the HO2S 1 low signal circuit Exhaust system leaks or restrictions Any water intrusion into the HO2S connector Engine coolant consumption-Refer to Loss of Coolant . Engine oil contaminated with fuel Any rich fuel injectors-Refer to Fuel Injector Diagnosis (w/J39021 or w/Tech 2) or Fuel Injector Diagnosis (w/CH47976) . An inaccurate mass air flow (MAF) sensor An intake air restrictor Evaporative emissions (EVAP) system malfunction-Inspect the EVAP control system. Refer to Inspection/Maintenance (I/M) System Check . Incorrect fuel pressure-Refer to Fuel System Diagnosis . Did you find and correct the condition?	-	Go to Step 12	Go to Step 7
7	Test for shorted terminals and poor connections at the HO2S 1. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 9
8	Test for shorted terminals and poor connections 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 12	Go to Step 10
9	NOTE: Refer to Heated Oxygen Sensor Resistance Learn Reset Notice . Replace the HO2S 1. Refer to Heated Oxygen Sensor 1 Replacement .Did you complete the replacement?	-	Go to Step 12	-
10	Test the HO2S 1 low signal circuit for an open or high resistance. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 11
11	Replace the PCM. Refer to Control Module References for replacement, setup, and programming. 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	In order to ensure that the performance of the catalyst has not been affected by the fault that set this DTC, operate the vehicle within the conditions for running and setting DTC P0420 and verify that P0420 runs and passes. Refer to DTC P0420 . Does the DTC run and pass?	-	Go to Step 14	Go to DTC P0420
14	Observe the Capture Info with a scan tool. Are there any DTCs that have not diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List - Vehicle	System OK
