P2105: Affordable Fix For Complex Automobile Fault Code
The automobile fault code P2105 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.
Therefore, the total cost of fixing the P2105 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.
P2105: Throttle Actuator Control System – Forced Engine Shutdown
The P2105 code is related to the Throttle Actuator Control (TAC) system.
This system calculates and controls the position of the throttle blade using vehicle electronics and components. The TAC system eliminates the need for a mechanical cable attachment from the accelerator pedal to the throttle body.
The TAC system components include the accelerator pedal position (APP) sensors, the throttle body, and the Powertrain Control Module (PCM).
These components interface together to ensure accurate calculations and control of the throttle position (TP). The P2105 code indicates a problem with the TAC system that has forced the engine to shut down. The throttle body assembly for the TAC system is similar to a conventional throttle body, but it uses a motor to control the throttle position instead of a mechanical cable.
The TP sensor is mounted in the throttle body assembly and is made up of two individual TP sensors.
FAQ
If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2105 fault code. This code is usually caused by a faulty Throttle Actuator Control (TAC), an open or shorted TAC harness, or a poor electrical connection in the TAC circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2105 fault code, it could be caused by a faulty Throttle Actuator Control (TAC), an open or shorted TAC harness, or a poor electrical connection in the TAC circuit. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
If the Throttle Actuator Control (TAC) circuit has a poor electrical connection causing the P2105 fault code, the engine light will turn on or the service engine soon warning light will appear. This issue can be caused by a faulty TAC, an open or shorted TAC harness, or a poor electrical connection in the TAC circuit. To fix this problem, it is recommended to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
Wrap Up
If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Throttle Actuator Control (TAC), open or shorted TAC harness, or poor electrical connection.
