Safety First: Before beginning any automotive repair, ensure the vehicle is turned off, the parking brake is engaged, and the battery is disconnected to prevent accidental electrical shorts or injury. If you are unsure about any step, consult a qualified mechanic.
Installation Steps:
- Locate the Existing Sensor: The brake sensor is typically located near the brake pedal arm, often mounted to the pedal assembly or a bracket above it. You may need to remove trim panels to access it.
- Disconnect Electrical Connector: Carefully disconnect the electrical connector from the old brake sensor. Press any release tabs or clips as needed.

- Install New Sensor: Insert the new Mopar Brake Sensor 68078700AE into the mounting location. Ensure it is properly seated and secured according to the vehicle's design.
- Reconnect Electrical Connector: Firmly attach the electrical connector to the new sensor until it clicks into place.
- Test Functionality: Reconnect the vehicle battery. Test the brake lights and any other affected systems (e.g., cruise control) to ensure proper operation.
- Reinstall Trim Panels: Replace any trim panels removed during the installation process.

5. Operation
The Mopar Brake Sensor 68078700AE operates by detecting the position of the brake pedal. When the brake pedal is pressed, the sensor's internal mechanism changes its state, sending an electrical signal to the vehicle's onboard computer. This signal is used to:
- Activate the vehicle's brake lights.
- Disengage cruise control when the brakes are applied.
- Provide input for other vehicle systems that rely on brake pedal status.
The sensor is designed for reliable and consistent performance, ensuring accurate brake pedal position detection.
6. Maintenance
The Mopar Brake Sensor 68078700AE is a sealed unit and generally requires no routine maintenance. However, to ensure its longevity and proper function:
- Keep the area around the brake pedal and sensor free from excessive dirt, debris, or moisture.
- Avoid applying excessive force or impact to the sensor during other vehicle maintenance.
- Regularly inspect the electrical connector for corrosion or damage.
7. Troubleshooting
If you experience issues that you suspect are related to the brake sensor, consider the following common problems and potential solutions:
- Brake Lights Not Working:
Possible Cause: Faulty brake sensor, wiring issue, or bulb failure.
Solution: Check brake light bulbs first. If bulbs are functional, inspect the sensor's electrical connection. If the sensor is suspected, replacement may be necessary. - Cruise Control Malfunction:
Possible Cause: A faulty brake sensor can prevent cruise control from engaging or cause it to disengage unexpectedly.
Solution: Verify the sensor is correctly installed and functioning. Many users have reported that replacing this specific sensor resolved intermittent cruise control issues. - Error Codes:
Possible Cause: The vehicle's diagnostic system may log specific error codes related to the brake pedal position sensor.
Solution: Use an OBD-II scanner to retrieve diagnostic trouble codes (DTCs). If codes point to the brake sensor, replacement is often the solution.
Always ensure the replacement part is a genuine Mopar component to guarantee compatibility and performance.
