How do you replace the accelerator pedal sensor on a 2005 pontiac gto?

The PCM detects that the MAP sensor voltage is more than 4.3 volts for 3 seconds.
This DTC may set due to poor idle characteristics. A possible cause may be uncontrolled fueling due to an open or high resistance in the HO2S 1 low signal circuit. Before replacing any component, ensure that this condition does not exist.
2
Turn ON the ignition, with the engine OFF.
Monitor the DTC information with the scan tool.
Is DTC P0641 also set?
--
YES - Go to Diagnostic Trouble Code (DTC) List - Vehicle
NO - Go to Step 3
3
Observe the throttle position (TP) sensor parameter with the scan tool.
Press the accelerator pedal slowly until the throttle is in the wide open position.
Release the accelerator pedal slowly until the throttle is returned to the closed position.
Repeat this procedure several times.
Does the TP sensor parameter increase steadily to more than the first specified value, and then decrease steadily returning to less than the second specified value?
98%
1%
YES - Go to Step 4
NO _ Go to DTC P0121
4
Start the engine.
Observe the MAP sensor parameter with a scan tool.
Is the voltage more than the specified value?
4.3 V
YES - Go to Step 6
NO - Go to Step 5

I would check the pedal position sensor. Do it when it's hot.

• Accelerator Pedal Position Sensor

  Description & Operation
  
  A power supply is applied on the Accelerator Pedal Position (APP) Sensor (main) power terminal from the PCM. The ground terminal is grounded with PCM. When the accelerator pedal is moved from the idle position to the fully opened position, the resistance between the accelerator pedal position sensor (main) output terminal and ground terminal will increase according to the depression.

Testing

1. Connect a suitable scan tool to the diagnostic connector. Select APP1 or APP2 percentage.
2. Turn the ignition switch to the ON position.
3. Measure the voltage at the PCM terminal and ground with connectors connected:
   
   APP1-8% load or 0.4 volts with the accelerator pedal releasedAPP1-60% load or 3.0 volts with the accelerator pedal depressedAPP2 -8% load or 0.4 volts with the accelerator pedal releasedAPP2 -60% load or 3.0 volts with the accelerator pedal depressed
4. If any check above does not meet the specifications, check connectors and wiring between the sensor and PCM. If ok, replace PCM.
5. If the measured values are outside the standard value range, or if the load % and/or voltage does not change smoothly, replace the sensor.

5. If the measured values are outside the standard value range, or if the load % does not change smoothly, replace the senso

no need to fear, this is a common problem. all you need to do is turn the key to the on position, push the pedal three times, then turn key to the off lock position. this is a typo in the manual. not sure why they have not corrected this issue. hope this helps.

Anti-theft light lit ? Could need to reprogram .
Battery Disconnect or Replacement Problems

Have to go to the dealers parts counter

There you will get the price,expensive

COST Around $25 - $35 and Fallow these Instructions PLEASE RATE ME!!!!!

Engine Oil Pressure Sensor and/or Switch Replacement

Tools Required

• J41712 Oil Pressure Switch Socket

Removal Procedure
Disconnect the oil pressure sensor electrical connector (1).

1. Important: Clean the area around the sensor before removal. This prevents debris from entering the engine. Use J41712 to remove the oil pressure sensor from the engine block.

Installation Procedure

1. If installing the old sensor, apply thread sealant GM P/N 12346004, (Canadian P/N 1093480), or equivalent. Notice: Refer to Fastener Notice in Service Precautions.
2. Use to install the J41712 oil pressure sensor to the engine block. Tighten the engine oil pressure sensor to 35 Nm (26 ft. lbs.) .Connect the oil pressure sensor electrical connector (1).
