DTC P1241

G92527t1: CHECK THE POWER SUPPLY TO THE ACCELERATOR PEDAL DEMAND SENSOR
1. TURN the ignition switch to the RUN position.
2. Measure the voltage between electrical connector PA1-5 and ground.
3. Measure the voltage between electrical connector PA1-4 and ground.

- Is the voltage less than 4.5 volts?

-> Yes
GO to Pinpoint Test G92527t2.

-> No
DIAGNOSE the electronic engine control system.

G92527t2: CHECK CONTINUITY OF THE ACCELERATOR PEDAL DEMAND SENSOR POWER SUPPLY CIRCUIT
1. Turn the ignition switch to the OFF position.
2. Disconnect the ECM electrical connector EN16 and the accelerator pedal electrical connector PA1.
3. Measure the resistance between EN16-13 and PA1-5.
4. Measure the resistance between EN16-12 and PA1-4.

- Is the resistance less than 5 ohms?

-> Yes
GO to Pinpoint Test G92527t3.

-> No
REPAIR the power supply circuit from the ECM to the accelerator pedal. CLEAR the DTC. TEST the system for normal operation.

G92527t3: CHECK THE ACCELERATOR PEDAL DEMAND SENSOR POWER SUPPLY FOR A SHORT CIRCUIT TO GROUND
1. Measure the resistance between PA1-5 and ground.
2. Measure the resistance between PA1-4 and ground.

- Is the resistance greater than 10,000 ohms?

-> Yes
DIAGNOSE the electronic engine control system.

-> No
REPAIR the power supply circuit from the ECM to the accelerator pedal. CLEAR the DTC. TEST the system for normal operation.
