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 P2122

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	Turn ON the ignition, with the engine OFF. Observe the accelerator pedal position (APP) sensor 1 voltage with the accelerator pedal in the rest position, with a scan tool. Is the APP sensor 1 voltage parameter less than the specified value?	0.13 V	Go to Step 4	Go to Step 3
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 accelerator pedal connector. Turn ON the ignition, with the engine OFF. Measure the voltage from the 5-volt reference circuit of APP sensor 1 to a good ground with a DMM. Refer to Circuit Testing . Does the DMM indicate voltage within the specified range?	4.8-5.2 V	Go to Step 5	Go to Step 6
5	Connect a fused jumper wire between the 5-volt reference circuit and the signal circuit of APP sensor 1. Observe the APP sensor 1 voltage parameter with a scan tool. Is the APP sensor 1 voltage parameter within the specified range?	4.8-5.2 V	Go to Step 11	Go to Step 7
6	Test the APP 5-volt reference circuit for the following conditions: An open A short to ground High resistance Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 8
7	Test the APP sensor 1 signal circuit for the following conditions: An open A short to ground High resistance Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 12	Go to Step 8
8	Test for an intermittent and for a poor connection at the APP sensor. 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
9	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 12	Go to Step 10
10	Replace the PCM. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	-	Go to Step 12	-
11	Replace the accelerator pedal assembly. Refer to Accelerator Pedal with Position Sensor 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 - Vehicle	System OK
