Code P2112 Suzuki Description
The P2112 diagnostic trouble code (DTC) for Suzuki vehicles indicates that the throttle actuator control throttle valve is stuck closed. This code is specifically related to the electronic throttle control system, which is responsible for regulating the amount of air entering the engine. The throttle valve is a crucial component that controls the airflow and ultimately the engine's performance. When the throttle valve gets stuck closed, it restricts the airflow, leading to a decrease in engine power and performance.
Common Causes of P2112 Suzuki
- Malfunctioning throttle actuator control system
- Faulty throttle body
- Stuck throttle plate
- Wiring issues
- Software glitch in the ECM
Symptoms of P2112 Suzuki
- Reduced acceleration
- Rough idling
- Stalling
- Poor fuel efficiency
- Loss of power
How to Fix P2112 Suzuki
- Diagnose the issue using a scan tool to confirm the P2112 code and identify the root cause.
- Inspect the throttle body and throttle plate for any obstructions or damage. Clean or replace as necessary.
- Check the throttle actuator control system and wiring for any faults. Repair or replace as needed.
- Clear the code and reset the ECM to see if the issue is resolved.
- Test drive the vehicle to ensure that the symptoms have been eliminated and the throttle valve is functioning properly.

2. What are the common symptoms of the P2112 code on a Suzuki?
Symptoms may include reduced engine power (limp mode), poor acceleration, unstable idle, the engine stalling, or the Check Engine Light being illuminated.
3. What causes the P2112 code to appear in a Suzuki?
Common causes include carbon buildup in the throttle body, a faulty throttle body, wiring or connector issues, a malfunctioning throttle actuator motor, or a failed engine control module (ECM).
4. Can I still drive my Suzuki with a P2112 code?
Driving with a P2112 code is not recommended, as the vehicle may experience reduced power or stalling, which could pose safety risks.
5. How do I fix the P2112 code on a Suzuki?
Start by cleaning the throttle body to remove any carbon buildup. If the issue persists, inspect the throttle actuator, wiring, and connectors. Replace faulty components if necessary.
6. Does the P2112 code always mean the throttle body is bad?
No, the issue could also be caused by electrical problems, such as damaged wiring or a malfunctioning throttle actuator, rather than the throttle body itself.
7. What tools are needed to diagnose and fix the P2112 code on a Suzuki?
You may need an OBDII scanner, a multimeter to check electrical connections, throttle body cleaner, and basic hand tools for removing and inspecting components.
8. How much does it cost to repair the P2112 code on a Suzuki?
Repair costs can vary. Cleaning the throttle body may cost little to nothing if done yourself, while replacing the throttle body or actuator can range from $200 to $600 or more, including parts and labor.
9. Can a dirty air filter cause the P2112 code on a Suzuki?
While a dirty air filter can restrict airflow, it is unlikely to directly cause the P2112 code. However, it can contribute to throttle body carbon buildup over time.
10. Will clearing the code with an OBDII scanner fix the P2112 issue?
Clearing the code may temporarily turn off the Check Engine Light, but the underlying issue must be resolved to prevent the code from reappearing.
