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 P0122

Step	Action	Values	Yes	No
Schematic Reference: Engine Controls Schematics Connector End View Reference: Engine Controls Connector End Views or Powertrain Control Module Connector End Views
1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Turn ON the ignition, with the engine OFF. Monitor the DTC information with the scan tool. Is DTC P0641 also set?	-	Go to DTC P0641	Go to Step 3
3	Observe the TP Sensor parameter with the scan tool. Is the voltage less than the specified value?	0.1 V	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 6	Go to Step 5
5	Test for an intermittent and for a poor connection at the throttle position (TP) sensor. 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 6
6	Turn OFF the ignition. Disconnect the TP sensor. Turn ON the ignition, with the engine OFF. Measure the voltage from the 5-volt reference circuit of the TP sensor to a good ground, with a DMM. Is the voltage more than the specified value?	4.8 V	Go to Step 7	Go to Step 8
7	Connect a 3-amp fused jumper wire between the 5-volt reference circuit of the TP sensor and the signal circuit of the TP sensor. Observe the TP sensor parameter with a scan tool. Is the voltage more than the specified value?	4.9 V	Go to Step 11	Go to Step 9
8	Test the 5-volt reference circuit between the powertrain control module (PCM) and the TP sensor for an open. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 13	Go to Step 10
9	Test the TP sensor signal circuit between the PCM and the TP sensor for a short to ground or an open. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 13	Go to Step 10
10	Test for an intermittent and for a poor connection at the 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	Replace the TP sensor. Refer to Throttle Position Sensor Replacement . 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	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 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
