The P2101 fault code indicates an issue with the Throttle Actuator Control Motor Circuit, specifically related to its range and performance. This code often arises when the engine control module (ECM) detects that the throttle actuator is not functioning within the expected parameters. Depending on the vehicle make and model, this can lead to various performance issues.

What are the symptoms of the P2101 code?

Drivers experiencing the P2101 code may notice symptoms such as:

• Reduced engine power or limp mode activation
• Unresponsive or delayed throttle response
• Check Engine Light illuminated on the dashboard
• Engine stalling or hesitation during acceleration

What causes the P2101 code?

Several factors can lead to the P2101 code being triggered, including:

• Faulty throttle position sensor
• Wiring issues such as broken connectors or short circuits
• Problems with the throttle body assembly
• Issues within the engine control module
• Intake air leaks affecting the throttle response

How to fix P2101?

To resolve the P2101 fault code, technicians typically take the following actions:

• Perform a diagnostic scan to confirm the fault code
• Inspect and repair any damaged wiring or connections to the throttle actuator
• Clean or replace the throttle body if necessary
• Check and potentially replace the throttle position sensor
• Reprogram or replace the engine control module if it is found to be defective
