Code P2106 RAM Description

The electronic Throttle Actuator Control (TAC) is a DC motor controlled by the Powertrain Control Module (PCM). There are 2 designs for the TAC, parallel and inline. The parallel design has the motor under the bore parallel to the plate shaft. The motor housing is integrated into the main housing. The inline design has a separate motor housing. An internal spring is used in both designs to return the throttle plate to a default position. The default position is typically a throttle angle of 7 to 8 degrees from the hard stop angle. The closed throttle plate hard stop prevents the throttle from binding in the bore. This hard stop setting is not adjustable and is set to result in less airflow than the minimum engine airflow required at idle. The P2106 code is set when the TAC system is in the Failure Mode Effects Management (FMEM) mode of forced limited power. The P2106 indicates the FMEM action is in effect due to a concern in an Electronic Throttle Control (ETC) related component or module

Frequently Asked Questions about P2106 RAM Code

1. What does the OBDII code P2106 mean for a RAM vehicle?

P2106 indicates that the Throttle Actuator Control (TAC) System has triggered a "Forced Limited Power" mode due to a detected issue.

2. What are the symptoms of the P2106 code on a RAM?

Symptoms may include reduced engine power, poor acceleration, a check engine light, and sometimes the vehicle entering limp mode.

3. What causes the P2106 code in a RAM?

Common causes include a malfunctioning throttle body, wiring issues, a faulty throttle position sensor, or problems with the PCM (Powertrain Control Module).

4. Can a dirty throttle body cause the P2106 code?

Yes, carbon buildup on the throttle body can cause it to stick or operate improperly, triggering the P2106 code.

5. How do you diagnose the P2106 code in a RAM?

Diagnosis involves using an OBDII scanner, inspecting the throttle body for damage or debris, checking the throttle position sensor, and testing the wiring and connectors for faults.

6. Is it safe to drive a RAM with the P2106 code?

Driving with the P2106 code is not recommended, as it can cause reduced power and pose safety risks, especially in traffic or on highways.

7. Can a faulty throttle position sensor cause the P2106 code?

Yes, a malfunctioning throttle position sensor can send incorrect signals to the PCM, leading to the activation of the P2106 code.

8. How do you fix the P2106 code on a RAM?

Repairs may include cleaning or replacing the throttle body, repairing damaged wiring, replacing the throttle position sensor, or reprogramming/updating the PCM.

9. Will disconnecting the battery clear the P2106 code?

Disconnecting the battery might temporarily clear the code, but the issue will return unless the underlying problem is resolved.

10. How much does it cost to fix the P2106 code on a RAM?

Repair costs vary, but cleaning the throttle body may cost $50â€“$100, while replacing components like the throttle body or PCM can range from $200 to $1,000 or more, depending on labor and parts.
