Code P2128 Chrysler Description
The P2128 Chrysler code indicates a problem with the Throttle/Pedal Position Sensor/Switch 'E' Circuit being too high. This sensor is crucial for the vehicle's electronic throttle control system, as it monitors the position of the throttle pedal and sends this information to the engine control module (ECM). The ECM uses this data to determine the appropriate throttle valve angle for optimal engine performance.
Common Causes of P2128 Chrysler
- Faulty Throttle/Pedal Position Sensor/Switch 'E'
- Damaged wiring or connectors
- Corrosion in the sensor circuit
- Issues with the ECM
- Electrical interference or short circuits
Symptoms of P2128 Chrysler
- Reduced engine power or acceleration
- Unresponsive throttle pedal
- Check Engine Light illuminated
- Rough idling or stalling
- Poor fuel efficiency
How to Fix P2128 Chrysler
- Perform a diagnostic scan to retrieve the fault codes and pinpoint the issue.
- Inspect the Throttle/Pedal Position Sensor/Switch 'E' and its wiring for any visible damage or corrosion.
- Test the sensor's voltage output using a multimeter to determine if it is within the acceptable range.
- Replace the Throttle/Pedal Position Sensor/Switch 'E' if it is found to be faulty.
- Clear the fault codes and perform a test drive to ensure the issue has been resolved.
Cost to Fix P2128 Chrysler

Frequently Asked Questions about P2128 Chrysler Code
1. What does the OBDII code P2128 mean for a Chrysler vehicle?
P2128 indicates a high voltage issue in the Throttle/Pedal Position Sensor/Switch 'E' Circuit, which is part of the electronic throttle control system.
2. What are the common symptoms of code P2128 in a Chrysler?
Symptoms may include reduced engine performance, the throttle not responding properly, the Check Engine Light illuminating, and the vehicle entering limp mode.
3. What causes the P2128 code to appear?
Common causes include a faulty throttle/pedal position sensor, damaged or corroded wiring, a poor electrical connection in the circuit, or a malfunctioning PCM (Powertrain Control Module).
4. Can I drive my Chrysler with the P2128 code?
Driving with this code is not recommended, as it can lead to reduced throttle response and unsafe driving conditions due to potential limp mode activation.
5. How do I diagnose the P2128 code in my Chrysler?
Start by inspecting the throttle/pedal position sensor and its wiring for damage or corrosion. Use a multimeter to check for proper voltage and continuity in the circuit.
6. How do I fix the P2128 code on a Chrysler?
Repairs may involve replacing the throttle/pedal position sensor, repairing or replacing damaged wiring, cleaning corroded connections, or updating/replacing the PCM if necessary.
7. How much does it cost to repair the P2128 code on a Chrysler?
The repair cost varies, but replacing a throttle/pedal position sensor typically ranges between $100-$300, depending on parts and labor.
8. Can a dirty throttle body cause the P2128 code?
While a dirty throttle body can cause throttle-related issues, it is not a direct cause of P2128. The code specifically relates to the sensor circuit voltage.
9. Does the P2128 code require reprogramming the PCM?
Reprogramming the PCM is only necessary if it is determined to be faulty or if a software update is required as part of the diagnostic process.
10. How can I prevent the P2128 code from recurring?
Regular maintenance, including inspecting and cleaning electrical connections and ensuring proper care of the throttle system, can help prevent this code from recurring.
