G240070T1 - G240070T3

A : DTC P1240

G240070t1 : 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 CA88 pin 5 (Y) and ground.
3. Measure the voltage between electrical connector CA88 pin 2 (Y) and ground.

- Is the voltage less than 4.5 volts?

-> Yes
Goto [G240070t2]

-> No
DIAGNOSE the electronic engine control system.

G240070t2 : 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 PI 1 and the accelerator pedal electrical connector CA 88.
3. Measure the resistance between PI 1 pin 13 (Y) and CA88 pin 5 (Y).
4. Measure the resistance between PI 1 pin 12 (OY) and CA88 pin 2 (OY).

- Is the resistance less than 5 ohms?

-> Yes
Goto [G240070t3]

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

G240070t3 : CHECK THE ACCELERATOR PEDAL DEMAND SENSOR POWER SUPPLY FOR A SHORT CIRCUIT TO GROUND
1. Measure the resistance between CA88 pin 5 (Y) and ground.
2. Measure the resistance between CA88 pin 2 (OY) 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.
