Code P2102 Chrysler Description

The Electronic Throttle Control (ETC) Motor is controlled by the Powertrain Control Module (PCM). The DC motor located in the Throttle Body drives the throttle blade. In order to decrease idle speed, along with spark and fuel delivery changes the PCM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the PCM commands the throttle plate open allowing more air to pass the throttle plate. The Diagnostic Trouble Code (DTC) will set when the PCM detects a low Motor Driver circuit.

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 $300â€“$600, while wiring repairs or PCM replacement can vary widely based on parts and labor.
