Step Action Values Yes No
Schematic Reference: Engine Controls Schematics
Connector End View Reference: Powertrain Control Module Connector End Views and 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
  1. Turn ON the ignition, with the engine OFF.
  2. Observe the accelerated pedal position (APP) sensor 2 voltage with the accelerator pedal in the rest position with a scan tool.
Is the voltage within the specified range?		 0.24-2 V Go to Step 4  Go to Step 3 
3
  1. Turn OFF the ignition.
  2. Disconnect the APP harness connector.
  3. Turn ON the ignition, with the engine OFF.
  4. Measure the voltage of the APP sensor 2, 5-volt reference circuit to a good ground with a DMM.
Is the voltage within the specified range?		 4.8-5.2 V Go to Step 6  Go to Step 9 
4 Is DTC P2138 also set? - Go to Diagnostic Trouble Code (DTC) List - Vehicle Go to Step 5 
5
  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 6  Go to Testing for Intermittent Conditions and Poor Connections

  1. Turn OFF the ignition.
  2. Disconnect the accelerator pedal harness connector.
  3. Turn ON the ignition, with the engine OFF.
  4. Observe the APP sensor 2 voltage parameter with a scan tool.
Is the voltage within the specified range?		 0-0.2 V Go to Step 7  Go to Step 11 
7
  1. Connect a fused jumper wire between the APP sensor 2 5-volt reference circuit and the APP sensor 2 signal circuit at the accelerator pedal harness connector.
  2. Observe the APP sensor 2 voltage parameter with a scan tool.
Does the scan tool indicate the APP sensor 2 voltage is within the specified range?		 4.8-5 V Go to Step 13  Go to Step 8 
8
  1. Turn OFF the ignition.
  2. Remove the fused jumper.
  3. Turn ON the ignition, with the engine OFF.
  4. Measure the voltage of the APP sensor 2 5-volt reference circuit with a DMM.
Is the voltage within the specified range?		 4.6-5.2 V Go to Step 10  Go to Step 9 
9 Does the DMM indicate voltage less than the specified value on the APP sensor 2 5-volt reference circuit? 5 V Go to Step 14  Go to Step 16 
10 Test the APP sensor 2 signal circuit for an open or for high resistance. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 22  Go to Step 12 
11 Test the APP sensor 2 signal circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 22  Go to Step 19 
12 Test the APP sensor 2 signal circuit for a short to ground. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 22  Go to Step 19 
13 Test the APP sensor 2 low reference circuit for an open or for high resistance. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 22  Go to Step 17 
14 Test the APP sensor 2 5-volt reference circuit for an open or for high resistance. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 22  Go to Step 15 
15 Test the APP sensor 2 5-volt reference circuit for a short to ground. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 22  Go to Step 19 
16 Test the APP sensor 2 5-volt reference circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 22  Go to Step 19 
17 Is DTC P1518 also set? - Go to Diagnostic Trouble Code (DTC) List - Vehicle Go to Step 18 
18 Test for an intermittent and for a poor connection at the accelerator pedal harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
Did you find and correct the condition?		 - Go to Step 22  Go to Step 20 
19 Test for an intermittent and for a poor connection at the throttle body harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
Did you find and correct the condition?		 - Go to Step 22  Go to Step 21 
20 Replace the accelerator pedal assembly. Refer to Accelerator Pedal Position Sensor Replacement .
Did you complete the replacement?		 - Go to Step 22  -
21 Replace the throttle body assembly. Refer to Throttle Body Assembly Replacement .
Did you complete the replacement?		 - Go to Step 22  -

  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 23
