• Solutions

The P2115 fault code indicates a problem with the Throttle/Pedal Position Sensor D, specifically related to its minimum stop performance. This sensor plays a crucial role in controlling the engine's air intake based on the driver's acceleration input. If the sensor is unable to accurately detect the positions required for proper engine control, it can lead to performance issues or potential engine stalling.

What are the symptoms of the P2115 code?

Symptoms associated with the P2115 code may include:

• Sudden loss of engine power or acceleration issues
• Erratic or unresponsive throttle
• Illuminated check engine light (CEL)
• Stalling or difficulty starting the engine
• Reduced fuel efficiency or performance.

What causes the P2115 code?

Common causes of the P2115 fault code include:

• Faulty throttle position sensor or associated wiring
• Accumulated dirt or carbon buildup on the throttle body
• Mechanical issues with the throttle plate
• Problems in the engine control unit (ECU) or software glitches
• Poor electrical connections or corroded connectors.

How to fix P2115?

To resolve the P2115 fault code, the following steps are generally recommended:

• Inspect the throttle position sensor and wiring for signs of damage or corrosion
• Clean the throttle body to remove any carbon buildup
• Check the throttle blade for proper operation and ensure it opens and closes without obstruction
• Test and, if necessary, replace the throttle position sensor
• Update or reprogram the engine control unit (ECU) if software issues are identified.
