• Solutions

The P2164 fault code indicates a problem with the Throttle/Pedal Position Sensor B, specifically related to the maximum stop performance. This code is triggered when the engine control module (ECM) detects that the throttle or pedal position is not reporting correctly, which can lead to poor engine performance and drivability issues. Understanding this code is crucial for diagnosing related problems in the vehicle's acceleration system.

What are the symptoms of the P2164 code?

Drivers may experience various symptoms, such as:

• Erratic engine behavior during acceleration
• Reduced power or hesitation while driving
• Check Engine Light illuminated on the dashboard
• Engine stalling or reluctance to accelerate
• Inconsistent throttle response when pressing the accelerator pedal

What causes the P2164 code?

Common causes for the P2164 code include:

• Faulty Throttle Position Sensor B
• Damaged wiring or connectors related to the throttle sensor
• Malfunction in the Engine Control Module (ECM)
• Poor mechanical connections within the throttle body
• Issues with the accelerator pedal assembly

How to fix P2164?

To resolve the P2164 code, follow these steps:

• Perform a thorough inspection of all associated wiring and connectors for damage or corrosion.
• Test the Throttle Position Sensor B with a multimeter to ensure it operates within specified parameters; replace it if faulty.
• Check the accelerator pedal for proper functionality and alignment; replace if necessary.
• Use a diagnostic scanner to clear the fault code after repairs and test drive the vehicle to ensure the issue is resolved.
