If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light, it could be due to the P2104 fault code. This code indicates a problem with the Throttle Actuator Control (TAC), which could be caused by a faulty TAC or a poor electrical connection in the TAC circuit.
It’s important to visually inspect the wiring harness and connectors for any damage or corrosion. The repair time for this issue is estimated at 1.0, and it’s crucial to address the problem promptly to avoid further damage to your vehicle. To interpret the fault code, you can use an OBD-II scanner or take your car to a mechanic for diagnosis.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |
| Repair Difficulty Level | 6.67 (Out of 10) |
The fault code on your car’s dashboard isn’t always reliable. That’s why it’s smart to keep an OBD scanner in your toolbox for quick, accurate diagnostics.
5 Symptoms Of P2104: Is Your Car Showing These?
If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2104 fault code.
Here are the symptoms to look out for:
- The P2104 fault code in an automobile can cause several symptoms.
- These include the engine light turning on or the service engine soon warning light appearing.
- The vehicle may also experience a reduction in power or acceleration.
- The throttle may become unresponsive or may only respond intermittently.
- The engine may also stall or have difficulty starting.
- Additionally, the vehicle may experience rough idling or poor fuel economy.
- It is important to address these symptoms promptly to prevent further damage to the vehicle.
P2104: Culprits Behind Your Engine’s Malfunction
P2104 fault code can be caused by a faulty TAC, open or shorted TAC harness, or poor electrical connection.
- The automobile fault code P2104 can be caused by a faulty Throttle Actuator Control (TAC).
- It can also be caused by an open or shorted Throttle Actuator Control (TAC) harness.
- Additionally, a poor electrical connection in the Throttle Actuator Control (TAC) circuit can also trigger this fault code.
It’s best not to rely on the car’s display for fault codes. Decoding the fault code is more accurate and reliable if you use a digital OBD scanner.
Fix Code P2104: Simple Steps To Get Your Car Running
To fix the p2104 fault code, check the possible causes and inspect related wiring harness, connectors, and components for damage.
- To fix the automobile fault code p2104, first, check the possible causes listed above.
- Then, visually inspect the related wiring harness and connectors.
- Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
- This fix will take an estimated repair time of 1.0 hour.
P2104: Affordable Fix For Your Car’s Throttle Control System
The factors that influence the cost of diagnosing and fixing the automobile fault code P2104 include the estimated repair time of 1.0 hour and the hourly rate charged by most auto repair shops, which ranges between $75 and $150.
These factors are crucial in determining the overall cost of fixing the fault code and should be considered when seeking repair services.
P2104: Throttle Actuator Control System – Forced Idle
The P2104 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 throttle body for the TAC system is similar to a conventional throttle body with a few exceptions.
One exception is the use of a motor to control the throttle position instead of a mechanical cable.
Another exception is the throttle position (TP) sensor, which is mounted in the throttle body assembly.
The P2104 code indicates a forced engine idle due to an issue with the Throttle Actuator Control System.
FAQ
