Condition:
Some customers may comment on an intermittent MIL/SES light Illuminated with a message center or an indicator that displays Reduced Engine Power. DTC P2138 - Accelerator Pedal Position (APP) Sensor 1-2 Correlation may be set. The voltage difference between APP sensor 1 and APP sensor 2 exceeds a predetermined value for more than 2 seconds. Refer to DTC P2138 in SI for further diagnostics.

Cause:
On some vehicles, the IP to body harness connector, which carries the APP signal to the ECM/PCM, is located in the left hand kick panel area and if the kick panel is not sealed properly, water enters and causes a short in the APP circuits setting a P2138 code.

Correction:
Important: Do Not replace the accelerator pedal assembly.

Locate the IP to body harness connector, which may be located in and around the left hand kick panel area. Check to see if there is a water leak into the area and repair as necessary.

the following link covers yours reqest The driver frontal loops 1 and 2 are the loops to the steering wheel air bag. The SDM(sensing and diagnostic module for the air bag) is seeing these circuits as open. There is a bullitin for problems with a loose connection for the yellow connector behind the left kick panel(right behind the e brake and hood release). I would remove the kick panel, and disconnect and reconnect the connector a couple times. See if the light goes out. Or wiggle and move the connector with the key on, as the light should go out if it makes good connection. If it does go out you need to replace this connector. Good luck.

There is a GM Technical Service Bulletin (TSB) on this issue, below is a summary;

#07-06-04-019A: Intermittent MIL/SES, DTC P2138 with Reduced Engine Power (Repair Instrument Panel (IP) to Body Harness Connector)

Models: 2005-2008 GM Passenger Cars and Light Duty Trucks (Including Saturn)
2005-2008 HUMMER H2
2006-2008 HUMMER H3
2005-2008 Saab 9-7X

Condition

Some customers may comment on an intermittent MIL/SES light Illuminated with a message center or an indicator that displays Reduced Engine Power. DTC P2138 - Accelerator Pedal Position (APP) Sensor 1-2 Correlation may be set. The voltage difference between APP sensor 1 and APP sensor 2 exceeds a predetermined value for more than a brief period. Refer to DTC P2138 in SI for further diagnostics.

Cause

On some vehicles, the IP to body harness connector, which carries the APP signal to the ECM/PCM, is located in the left hand kick panel area or inside the IP. Water intrusion into these areas could cause an electrical short in the APP circuits setting a P2138 code.

Correction

Note: Make sure that no add-on/aftermarket equipment is electrically connected to the APP signals or to the other ECM/PCM five volt reference or return lines. These can generate false P2138 and/or other ETC System DTCs. If there are other engine DTCs besides P2138, such as MAP sensor faults (i.e. P0107, P0108), resolve these first before attempting to diagnose P2138 DTCs.

Important: Refer to DTC P2138 in SI to confirm that the ETC pedal is operating correctly.

Locate the IP to body harness connector, which may be located in and around the left hand kick panel area or inside the IP. Check to see if there is a water leak into the area and repair as necessary. Use a water hose to determine the source of a water leak and effectiveness of repair. Some examples of potential water leaks are: A-pillar seals, sunroof drain lines (if so equipped) and windshield/cowl sealing. Finally, repair or replace the IP to body harness connector, making sure no corrosion or debris is left on or between the terminals.

Loosen and pull back the carpeting in the back of the trunk behind the taillights.

Step 2 Remove the plastic wingnuts that secure the taillight to the vehicle's body.

Step 3 Separate the taillights from the vehicle's body, but do not disconnect the wiring.
Installing the Connector

Step 1 Examine the wiring harness on each taillight. There will be a plastic connector on each side that must be separated to insert the wiring harness connector.

Step 2 Thread the trailer wiring connectors through holes in the body behind each taillight. Follow the instructions provided with the connector to determine which connector belongs in which side of the vehicle.

Step 3 Insert the wiring connectors into the vehicle's wiring harness.
Reinstalling the Taillights

Step 1 Push the taillights into position against the body and reinstall the plastic wingnuts that secure them. Be careful not to crush the wiring.

Step 2 Route the trailer wiring underneath the carpeting in the trunk, so that the trailer connector can extend out between the trunk lid and bumper when in use, and be tucked into the trunk when not in use.

Step 3 Reposition the trunk carpet over the taillight housing.

Condition:
Some customers may comment on an intermittent MIL/SES light Illuminated with a message center or an indicator that displays Reduced Engine Power. DTC P2138 - Accelerator Pedal Position (APP) Sensor 1-2 Correlation may be set. The voltage difference between APP sensor 1 and APP sensor 2 exceeds a predetermined value for more than 2 seconds.
