P1247 - FAULT CODE - OBD2

P1247 ACURA, HONDA: ACCELERATOR PEDAL POSITION SENSOR 2 CIRCUIT MALFUNCTION

Modern throttle control systems include an electronic application that contains sensors, a motor, and an actuator. These collect data that is sent to the Engine Control Module (ECM), which controls the timing to open or close the throttle valve.

In the case of the APP Sensor (Accelerator Pedal Position), a sensor installed on the accelerator pedal, captures the position of the pedal and based on it provides an electrical signal to the ECM and consequently, the controller controls the pedal angle based on the information received.

When the P1247 OBDII fault code is set on Acura and Honda vehicles, it is because a malfunction has been detected in the number 2 Throttle Pedal Position Sensor circuit.

• Check Engine light illuminated.
• Loss of engine power.
• Difficulties during acceleration.

When the P1247 OBD2 diagnostic code is set it is for one of the following reasons:

• Accelerator Pedal Position Sensor 2 may have damage to its wires or connectors.
• The Accelerator Pedal Position Sensor 2 electrical connections may have inconsistencies, which cause a short in the circuit.
• APP Sensor may be in bad condition.

To troubleshoot DTC P1247 OBDII you must do the following:

• Consult the Technical Service Bulletins.
• Inspect the wiring and connectors related to the Accelerator Pedal Position Sensor 2 and check that these components meet the conditions for proper operation. Repair or replace if common deficiencies are found.
• Using the appropriate tools you should take readings of the Accelerator Pedal Position Sensor 2 circuit voltages to verify that a short or open circuit is not present. If electrical deficiencies are found, check the continuity of the wiring and make any necessary corrections.
• Following the manufacturer's recommended diagnostic steps, check the APP Sensor 2 for damage. If you discover that the sensor is in poor condition, proceed with its replacement.
