Jeep Gladiator Brake Pedal Position Sensors
Jeep Gladiator Brake pedal position sensors
Starting at $71.95, AutoBuffy stocks 2 brake pedal position sensors from Mopar and Standard Ignition to fit the Jeep Gladiator. This sensor tells the vehicle's ECU and ABS module exactly when and how far the brake pedal is pressed. A failed sensor can disable brake lights, confuse stability control, and trigger no-start conditions on push-button ignition vehicles.
Signs your Jeep Gladiator needs a new brake pedal position sensor
- Brake lights stay on constantly or fail to illuminate at all when the pedal is pressed
- Push-button ignition will not crank — the ECU does not detect a depressed brake pedal
- ABS, traction control, or stability control warning lights illuminate on the dashboard
- Transmission refuses to shift out of Park on vehicles with a brake-shift interlock system
- Cruise control disengages randomly or cannot be set, even on flat roads
- Stored fault codes related to brake switch input signal (open circuit, short, or out-of-range voltage)
Which brake pedal position sensor should you buy for your Jeep Gladiator?
The main decision is whether to buy an OEM-equivalent or upgraded replacement, and whether your Jeep Gladiator uses a single-function brake light switch or a multi-signal position sensor with analog voltage output. Some platforms use a combined unit that handles both brake lights and ABS/ESC input; verify your application before ordering.
OEM-Equivalent (Direct Fit)
Best for
Drivers who want a like-for-like replacement with no calibration
What you get
Matches original connector, signal range, and mounting bracket exactly
Multi-Signal Position Sensor
Best for
Vehicles with advanced ABS, ESC, or adaptive cruise that need analog pedal-travel data
What you get
Continuous voltage output proportional to pedal travel, not just an on/off signal
Combined Brake Switch + Sensor
Best for
Applications where brake lights and ECU input share one housing
What you get
Single-unit replacement that restores both functions simultaneously, reducing labor
Premium / OEM Supplier Grade
Best for
High-mileage vehicles or those in extreme climates where longevity matters most
What you get
Higher-spec sealing, wider temperature tolerance, and longer service intervals

The brake pedal position sensor mounts on the brake pedal bracket above the pedal arm and is reached from inside the cabin under the dashboard. Disconnect the harness, rotate or press the retaining tab to release the old sensor, then snap the new unit into place and reconnect the connector. After installation, verify brake lights operate correctly and clear any stored fault codes with a scan tool before returning the vehicle to service.
Frequently asked questions
How much does it cost to replace brake pedal position sensors on a Jeep Gladiator?
Parts start at $71.95 at AutoBuffy. The sensor itself is the main expense; labor is typically low because the unit is accessible above the brake pedal arm. Most independent shops complete the job in under an hour, making total out-of-pocket cost relatively modest compared to other brake system repairs.
Can I drive my Jeep Gladiator with a bad brake pedal position sensor?
Driving with a failed sensor is not recommended. If brake lights are inoperative, you create a serious rear-end collision risk and a legal liability. On vehicles with electronic shift interlock or push-button start, a failed sensor may also leave you stranded. Treat this as a high-priority repair, not a defer-it item.
Will a brake pedal position sensor trigger a check engine or ABS light on a Jeep Gladiator?
Yes. A faulty sensor commonly sets fault codes that illuminate the ABS, traction control, or stability control warning lights, and may also trigger the check engine light. Retrieving the stored codes with an OBD-II scanner before buying parts helps confirm the sensor — rather than wiring or the brake module — is the root cause.
Does the brake pedal position sensor need to be calibrated after replacement on a Jeep Gladiator?
Basic on/off brake light switches require no calibration — correct mounting position restores function immediately. Analog position sensors on vehicles with advanced ESC or brake-by-wire systems may require a pedal-travel calibration routine through a scan tool. Check your service information before replacing to know which type your Jeep Gladiator uses.
How do I test a brake pedal position sensor on a Jeep Gladiator before replacing it?
Use a multimeter to check for switched voltage at the output wire while pressing the pedal. For analog sensors, confirm the output voltage rises and falls smoothly across the full pedal stroke with no dropouts. You can also check for continuity with the pedal released versus depressed. A scan tool live-data view of brake switch status is the fastest method.
How long does a brake pedal position sensor last on a Jeep Gladiator?
Most sensors last many years under normal use, but failure rates increase with age, corrosion at the connector, or physical wear from repeated pedal contact. Vehicles in salt-belt regions or with high stop-and-go mileage tend to see earlier failures. Inspect the connector and harness for corrosion whenever symptoms appear before condemning the sensor itself.
