P2106 on a Ford F150: Causes and Fixing

The P2106 code on a Ford F150 refers to a fault in the Throttle Actuator Control (TAC) system. This code specifically indicates that the Throttle Actuator Control System has detected a performance issue in the Forced Limited Power (FLP) mode.

P2106 on a Ford F150

Here are some possible causes of the P2106 code on a Ford F150:

1. A malfunctioning throttle actuator control module
2. A faulty throttle actuator control motor or position sensor
3. A damaged or frayed wiring harness that connects the throttle actuator control system components
4. A malfunctioning Electronic Throttle Control (ETC) system
5. A dirty or clogged throttle body

To diagnose and fix the problem, you may need to take your Ford F150 to a certified mechanic or Ford dealership. They will likely use a diagnostic tool to read the error code and troubleshoot the issue further. In some cases, a simple cleaning of the throttle body or replacement of a damaged component may solve the issue.

P2106 on a Ford F150 Tech Note

Symptom:

• Check Engine Light (CEL) is illuminated
• Reduced engine power or engine stuck in idle
• Poor throttle response

Trouble Code: P2106 – Throttle Actuator Control System Forced Limited Power

Possible Causes:

• Malfunctioning throttle actuator control module
• Faulty throttle actuator control motor or position sensor
• Damaged or frayed wiring harness that connects the TAC system components
• Malfunctioning Electronic Throttle Control (ETC) system
• Dirty or clogged throttle body

Diagnostic Steps:

1. Check for any other trouble codes stored in the PCM.
2. Inspect the throttle body for any signs of dirt, debris, or carbon buildup. Clean or replace the throttle body if necessary.
3. Inspect the wiring harness that connects the TAC system components for any damage or frayed wires. Repair or replace the wiring harness if necessary.
4. Check the throttle actuator control motor and position sensor using a multimeter. Replace these components if they are found to be faulty.
5. Use a diagnostic tool to test the throttle actuator control module and the ETC system. Replace these components if they are found to be malfunctioning.

Note: Proper diagnosis of the P2106 code on a Ford F150 may require the use of specialized diagnostic tools and equipment. If you are not comfortable performing these steps yourself, it is recommended that you take your vehicle to a certified mechanic or Ford dealership for proper diagnosis and repair.

It’s important to note that these symptoms are not exclusive to the P2106 code, and there may be other possible causes for them as well. Therefore, proper diagnosis by a certified mechanic or Ford dealership may be necessary to determine the exact cause of the issue.

P2106 on a Ford F150 Description

The P2106 code on a Ford F150 is an OBD-II diagnostic trouble code that indicates a fault in the Throttle Actuator Control (TAC) system. This code specifically indicates that the Throttle Actuator Control System has detected a performance issue in the Forced Limited Power (FLP) mode.

The Throttle Actuator Control (TAC) system is responsible for regulating the engine’s throttle based on driver inputs. The TAC system includes the throttle actuator control module, throttle actuator control motor, position sensor, wiring harness, and Electronic Throttle Control (ETC) system.

When the TAC system detects a fault, such as a malfunctioning throttle actuator control module, faulty throttle actuator control motor or position sensor, damaged wiring harness, or malfunctioning ETC system, it will set the P2106 code and illuminate the Check Engine Light (CEL).

Other symptoms may include reduced engine power or engine stuck in idle, poor throttle response, engine surging or stalling, and an illuminated ETC system warning light.

To diagnose and fix the issue, a certified mechanic or Ford dealership may use a diagnostic tool to read the error code and troubleshoot the issue further.

Depending on the exact cause of the issue, solutions may include cleaning or replacing the throttle body, repairing or replacing the wiring harness, or replacing faulty TAC system components such as the throttle actuator control module, motor, or position sensor.

How much does it cost to diagnose and fix the P2106 on a Ford F150?

The cost to diagnose and fix the P2106 code on a Ford F150 can vary depending on several factors, such as the severity of the issue, the exact cause of the code, and the labor rates of the mechanic or Ford dealership performing the repairs.

Diagnosis costs can range from $50 to $150 or more, depending on the diagnostic equipment used and the time it takes to troubleshoot the issue.

Repair costs can vary widely depending on the exact cause of the issue. For example, if the issue is simply a dirty throttle body that needs cleaning, the cost may be relatively low, typically around $100 to $150. However, if the issue is a malfunctioning throttle actuator control module or a faulty Electronic Throttle Control (ETC) system, the cost could be much higher, ranging from $500 to $1,000 or more.

It’s important to note that these are rough estimates, and the actual cost to diagnose and fix the P2106 code on a Ford F150 may vary based on several factors. It’s always best to get an estimate from a certified mechanic or Ford dealership before proceeding with any repairs.

How to fix the P2106 on a Ford F150?

Fixing the P2106 code on a Ford F150 will depend on the specific cause of the issue. Here are some general steps that can be taken to fix the P2106 code:

1. Inspect the throttle body: A dirty or clogged throttle body can cause issues with the TAC system’s performance and trigger the P2106 code. Cleaning or replacing the throttle body may solve the issue. To clean the throttle body, remove it from the engine and use a throttle body cleaner to clean the inside. Be sure to follow the instructions on the cleaner carefully.
2. Inspect the wiring harness: Check the wiring harness that connects the TAC system components for any damage or frayed wires. Repair or replace the wiring harness if necessary.
3. Check the throttle actuator control motor and position sensor: Use a multimeter to check the throttle actuator control motor and position sensor. Replace these components if they are found to be faulty.
4. Check the Electronic Throttle Control (ETC) system: Use a diagnostic tool to test the throttle actuator control module and the ETC system. Replace these components if they are found to be malfunctioning.
5. Clear the code: After fixing the issue, use a diagnostic tool to clear the P2106 code from the PCM. This will turn off the Check Engine Light.

It’s important to note that proper diagnosis of the P2106 code on a Ford F150 may require the use of specialized diagnostic tools and equipment. If you are not comfortable performing these steps yourself, it is recommended that you take your vehicle to a certified mechanic or Ford dealership for proper diagnosis and repair.
