Code P2102 Chrysler Description
The P2102 code for Chrysler vehicles indicates a problem with the Electronic Throttle Control (ETC) motor circuit being too low. The ETC system is responsible for controlling the throttle opening electronically rather than mechanically. When this code is triggered, it means that the Engine Control Module (ECM) has detected a voltage signal from the ETC motor that is lower than expected, indicating a potential issue with the motor or its circuit. This can lead to a variety of performance issues and potential safety concerns, as the throttle control is crucial for regulating the engine's power output.
Common Causes of P2102 Chrysler
- Faulty ETC motor
- Wiring or connector issues in the ETC motor circuit
- Corrosion or damage to ETC motor components
- ECM software or hardware issues
- Electrical system malfunctions
Symptoms of P2102 Chrysler
- Reduced engine power
- Vehicle stalling or surging
- Difficulty accelerating
- Illuminated Check Engine Light
- Vehicle going into "limp mode" to prevent further damage
How to Fix P2102 Chrysler
- Diagnose the ETC motor circuit using a multimeter to check for proper voltage levels
- Inspect the wiring and connectors for any damage or corrosion, repairing or replacing as needed
- Test the ETC motor itself to determine if it is functioning correctly
- Clear the fault codes and reset the ECM
- Test drive the vehicle to ensure proper throttle response and no reoccurrence of the code
Cost to Fix P2102 Chrysler
The cost of repairing a P2102 code on a Chrysler vehicle can vary depending on the specific cause of the issue. In general, replacing a faulty ETC motor can cost between $200 to $500, while addressing wiring or connector problems may range from $100 to $300. Labor costs can add another $100 to $300 on top of parts costs. It's important to consider that diagnosis time and labor rates can vary, so it's recommended to obtain quotes from local auto repair shops to get a more accurate estimate.

Frequently Asked Questions about P2102 Chrysler Code
1. What does the OBDII code P2102 mean on a Chrysler vehicle?
P2102 indicates an issue with the Electronic Throttle Control (ETC) Motor Circuit, specifically that the circuit is operating at a low voltage or has insufficient power.
2. What are the common symptoms of the P2102 code in a Chrysler?
Symptoms may include poor acceleration, reduced engine power (limp mode), throttle unresponsiveness, and the illumination of the check engine light.
3. What causes the P2102 code to appear in a Chrysler?
Common causes include a faulty throttle body, damaged wiring or connectors in the circuit, a failing Electronic Throttle Control motor, or issues with the Powertrain Control Module (PCM).
4. Can a failing battery cause the P2102 code?
Yes, a weak or failing battery can result in low voltage to the ETC motor circuit, potentially triggering the P2102 code.
5. How can I diagnose the P2102 code on my Chrysler?
Start by inspecting the throttle body and its wiring for damage or corrosion. Use a multimeter to check for proper voltage and continuity in the circuit. Scan for additional codes that may provide clues.
6. Is it safe to drive with the P2102 code active?
Driving with this code is not recommended as it can cause reduced engine power, making it unsafe to operate the vehicle, especially in traffic or on highways.
7. How do I fix the P2102 code on a Chrysler?
Repairs may include replacing the throttle body, repairing damaged wiring or connectors, or reprogramming or replacing the PCM if necessary.
8. Can cleaning the throttle body resolve the P2102 code?
If the issue is caused by dirt or carbon buildup affecting the throttle motor, cleaning the throttle body might help. However, if the motor or circuit has failed, cleaning alone will not resolve the issue.
9. Will disconnecting the battery clear the P2102 code?
Disconnecting the battery may temporarily clear the code, but it will not fix the underlying problem. The code will return unless the root cause is addressed.
10. How much does it cost to repair the P2102 code on a Chrysler?
Repair costs can vary depending on the cause. Throttle body replacement may cost $300–$600, while wiring repairs or PCM replacement can vary widely based on parts and labor.
