Common Questions
What does P2106 mean and how does it affect my car?
The P2106 code signifies a throttle control problem, which can lead to reduced engine power and performance. If ignored, it could result in stalling or unsafe driving conditions.
What are the most common causes of P2106 and how much does it cost to fix?
Common causes include a faulty throttle position sensor ($150 - $300), wiring issues ($100 - $200), or a dirty throttle body ($75 - $150). Addressing these promptly can save on further repairs.
Can I drive my car with P2106 or should I stop immediately?
While you may be able to drive short distances, it's not advisable. The vehicle may enter limp mode, limiting speed and throttle response, which can pose safety risks.
How can I diagnose P2106 myself using GeekOBD APP?
You can use the GeekOBD APP to scan for the P2106 code, review freeze frame data for context, and monitor live data for the throttle position sensor to check for irregularities.
What vehicles are most commonly affected by P2106?
Commonly affected vehicles include the 2010-2015 Ford Fusion, 2011-2016 Chevrolet Cruze, and various models from Toyota and Honda. Check for any recalls or technical service bulletins related to throttle issues.
How can I prevent P2106 from happening again?
Regular maintenance, including cleaning the throttle body and inspecting wiring connections, can help prevent the recurrence of P2106. Using quality fuel and following manufacturer service intervals is also advisable.
What is P2106?
The Diagnostic Trouble Code (DTC) P2106 indicates a 'Throttle Control System Range/Performance Problem.' This code usually arises when the Engine Control Module (ECM) detects that the throttle position does not match the expected range based on the accelerator pedal input. Essentially, the ECM is monitoring the throttle body and its position to manage air intake and engine performance. When there’s a discrepancy, it triggers the P2106 code. This issue can lead to significant performance problems, such as reduced engine power or even stalling, as the vehicle attempts to limit throttle response to prevent potential engine damage. Vehicles commonly affected by this code include the 2010-2015 Ford Fusion and 2011-2016 Chevrolet Cruze. If you experience this code, it's essential to address it promptly, as it can lead to unsafe driving conditions and increased emissions. Regular maintenance, including cleaning the throttle body and checking wiring connections, can prevent this issue from recurring. Understanding the implications of DTC P2106 can help owners take proactive measures to maintain their vehicle's performance and safety.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P2106 is present:
- The check engine light may illuminate, indicating a fault in the throttle control system.
- Drivers may notice engine hesitation or stalling during acceleration, making it difficult to maintain speed.
- Fuel economy may decrease significantly, often by 10-15%, as the engine struggles to perform optimally.
- You might experience erratic engine behavior, such as sudden drops in power or unresponsive acceleration.
- In severe cases, the vehicle may enter 'limp mode,' severely limiting speed and throttle response to protect the engine.
Possible Causes
Most common causes of P2106 (ordered by frequency):
- The most common cause is a faulty throttle position sensor, with an estimated likelihood of 40%. This sensor relays the position of the throttle to the ECM, and if it fails, the readings become erratic.
- Another cause could be wiring issues or poor connections, accounting for about 30% of cases. Damaged wires or loose connectors can disrupt the signal sent to the ECM.
- A dirty or malfunctioning throttle body is also a significant cause, contributing to around 20% of issues. Regular cleaning can prevent buildup that leads to improper throttle response.
- Less common but serious causes include ECM failure, which can lead to miscommunication between the throttle body and engine, often requiring replacement.
- In rare instances, mechanical issues within the throttle body, such as sticking components, can trigger the code, necessitating a thorough inspection and repair.

Diagnostic Steps
Professional P2106 Diagnosis Process
Follow these systematic steps to accurately diagnose P2106. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion (5-10 minutes)
Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context (10-15 minutes)
Step 3: Component testing - Use a multimeter or specific diagnostic tools to test the throttle position sensor and wiring for proper functionality (20-30 minutes)
Step 4: System function test - Verify proper operation after repairs and clear codes using the GeekOBD APP to ensure no further issues arise (10-15 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to confirm repair success and throttle responsiveness (15-20 minutes)
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
