Code P2118 Scion Description
The P2118 code for Scion vehicles indicates a problem with the Throttle Actuator Control Motor's current range or performance. The throttle actuator control motor is responsible for controlling the opening and closing of the throttle valve in response to driver input and engine conditions. When the engine control module (ECM) detects that the current range or performance of the throttle actuator control motor is outside of the expected parameters, it triggers the P2118 code.
Common Causes of P2118 Scion
- Faulty throttle actuator control motor
- Wiring or connector issues
- Malfunctioning throttle position sensor
- Problems with the ECM
- Mechanical issues with the throttle body
Symptoms of P2118 Scion
- Erratic throttle response
- Stalling or rough idling
- Poor acceleration
- Engine misfires
- Limp mode activation
How to Fix P2118 Scion
- Diagnose the issue by connecting a scan tool to read the code and perform further testing to identify the root cause.
- Inspect the throttle actuator control motor, wiring, and connectors for any signs of damage or wear.
- Test the throttle position sensor to ensure it is functioning correctly.
- Check the ECM for any faults or errors that may be contributing to the issue.
- Replace or repair any faulty components as necessary to resolve the P2118 code.
Cost to Fix P2118 Scion
The typical repair costs for resolving a P2118 code can vary depending on the specific cause of the issue. In general, replacing a faulty throttle actuator control motor can cost between $200 to $500, including parts and labor. However, additional costs may be incurred if other components need to be replaced or if more extensive diagnostics are required. It is advisable to contact local auto repair shops for a more accurate estimate based on your vehicle's make and model. Keep in mind that labor rates can vary, with hourly rates typically ranging from $80 to $150.

Frequently Asked Questions about P2118 Scion Code
What does the OBDII code P2118 mean on a Scion?
P2118 indicates an issue with the Throttle Actuator Control (TAC) Motor Current Range/Performance, meaning the electronic throttle control system is detecting abnormal current or performance in the throttle actuator motor.
What are the common symptoms of the P2118 code on a Scion?
Symptoms include reduced engine power, the throttle not responding properly, the check engine light illuminating, and the vehicle possibly entering "limp" mode.
What causes the P2118 code on a Scion?
Common causes include a faulty throttle actuator motor, damaged or corroded wiring in the throttle control circuit, a malfunctioning throttle body, or an issue with the engine control module (ECM).
Can I drive my Scion with the P2118 code?
Driving with the P2118 code is not recommended, as the vehicle may experience reduced performance or enter limp mode, potentially creating unsafe driving conditions.
How is the P2118 code diagnosed on a Scion?
A mechanic will use a scan tool to retrieve the code, inspect the throttle body and wiring for damage or corrosion, test the throttle actuator motor, and check the ECM for faults.
How can I fix the P2118 code on my Scion?
Repairs may include cleaning or replacing the throttle body, repairing or replacing damaged wiring, replacing the throttle actuator motor, or reprogramming or replacing the ECM if necessary.
How much does it cost to fix the P2118 code on a Scion?
Repair costs vary but typically range from $150 to $800 depending on whether the throttle body, wiring, or ECM requires replacement or repair.
Can a dirty throttle body cause the P2118 code?
Yes, carbon buildup on the throttle body can interfere with the throttle actuator motor's performance and trigger the P2118 code.
Will clearing the code with a scan tool fix the problem?
Clearing the code will remove the check engine light temporarily, but the issue causing the code will still need to be addressed to prevent it from returning.
Is the P2118 code specific to Scion vehicles?
No, P2118 is a generic OBDII code and can appear on other makes and models, but the specific diagnosis and repair steps may vary.
