Code P2106 Saturn Description
The P2106 diagnostic trouble code for Saturn vehicles indicates an issue with the Throttle Control System Performance, specifically that Throttle Limitations are Active. This code is typically triggered when the Engine Control Module (ECM) detects that the actual throttle position does not match the desired throttle position. In simpler terms, the throttle is not responding as it should, leading to limitations in the vehicle's performance.
Common Causes of P2106 Saturn
- Faulty electronic throttle control system
- Dirty throttle body
- Wiring or connector issues in the throttle control system
- Faulty throttle position sensor
- ECM software or hardware issues
Symptoms of P2106 Saturn
- Reduced engine power
- Hesitation or stalling when accelerating
- Rough idling
- Vehicle going into "limp mode"
How to Fix P2106 Saturn
- Perform a thorough inspection of the electronic throttle control system, including the throttle body, sensors, and wiring.
- Clean the throttle body to remove any carbon buildup or debris that may be affecting its operation.
- Test the throttle position sensor to ensure it is functioning correctly and replace if necessary.
- Check and repair any wiring or connector issues in the throttle control system.
- Reset the ECM and perform a throttle relearn procedure to recalibrate the system.
Cost to Fix P2106 Saturn

Frequently Asked Questions about P2106 Saturn Code
1. What does the OBDII code P2106 mean on a Saturn?
P2106 indicates that the powertrain control module (PCM) has detected a throttle control system performance issue and has activated a fail-safe or "limp mode" to limit throttle operation.
2. What are the common symptoms of the P2106 code in a Saturn vehicle?
Symptoms may include reduced engine power, hesitation during acceleration, a throttle that doesn’t respond properly, and the check engine light being illuminated.
3. What causes the P2106 code to appear on a Saturn?
Common causes include a malfunctioning throttle body, a faulty throttle position sensor, wiring issues, a defective accelerator pedal position sensor, or problems with the PCM.
4. Can I drive my Saturn with the P2106 code active?
While the vehicle may still be drivable, it will likely be in limp mode with limited power. Driving in this condition for extended periods is not recommended as it could cause further damage.
5. How is the P2106 code diagnosed in a Saturn?
A technician will use a scan tool to check for related codes, inspect the throttle body and sensors, examine wiring and connectors for damage, and perform tests on the throttle control system components.
6. How do you fix the P2106 code on a Saturn?
Repairs may include cleaning or replacing the throttle body, replacing a faulty throttle position sensor or accelerator pedal position sensor, repairing damaged wiring, or updating/replacing the PCM.
7. Can a dirty throttle body trigger the P2106 code on a Saturn?
Yes, a dirty or carbon-clogged throttle body can restrict airflow and cause the PCM to detect a performance issue, triggering the P2106 code.
8. Does the P2106 code always mean the throttle body needs replacement?
No, the issue could also stem from sensors, wiring, or even software glitches in the PCM. Proper diagnosis is essential to determine the exact cause.
9. What tools are needed to diagnose and repair the P2106 code on a Saturn?
You’ll typically need an OBDII scan tool, a multimeter for electrical testing, and basic hand tools for inspecting and replacing components.
10. How much does it usually cost to fix the P2106 code on a Saturn?
Repair costs can vary widely depending on the cause, ranging from $150–$500 for cleaning or replacing the throttle body or sensors, and potentially more if the PCM needs replacement or reprogramming.
