How many ABS sensors does a 2014 Ram 1500 have?
The 2014 Ram 1500 uses four ABS wheel speed sensors—one at each wheel.
The anti-lock braking system on this generation of Ram pickups relies on independent speed measurements from all four wheels to control braking force, maintain stability, and assist with traction control. This configuration matches the standard four-wheel ABS setup found on most light-duty trucks from that era.
Sensor count and locations
To map out where the sensors sit and their roles, the following list outlines each wheel's speed sensor and location.
- Front-left wheel speed sensor — located in the left front hub assembly; monitors speed for the front-left wheel.
- Front-right wheel speed sensor — located in the right front hub assembly; monitors speed for the front-right wheel.
- Rear-left wheel speed sensor — located near the rear axle; monitors speed for the rear-left wheel.
- Rear-right wheel speed sensor — located near the rear axle; monitors speed for the rear-right wheel.
Concluding paragraph: With four wheel speed sensors, the Ram 1500 can independently monitor each wheel’s rotation, enabling reliable ABS operation and supporting traction and vehicle stability systems across all four corners.
Variations and practical notes
While the standard configuration is four sensors, some trims or braking setups may implement the sensors differently, particularly if rear brakes are drum-style or if aftermarket modifications are present. For precise confirmation, inspect the vehicle’s hubs or consult the owner's manual or a service bulletin for that specific truck.
Why the sensor count matters
Having a sensor at every wheel ensures the ABS controller has complete, corner-specific data to optimize braking pressure during adverse conditions, which enhances safety and steering control.
Summary
The 2014 Ram 1500 is equipped with four ABS wheel speed sensors—one at each wheel—forming a four-corner system that supports ABS, traction control, and stability functions across the vehicle.
What is the ABS light on a 2014 Dodge Ram 1500?
A 2014 Ram 1500 ABS light on is likely caused by a faulty wheel speed sensor or damaged wiring, but it could also be a bad ABS module or low brake fluid. To start, you can use an OBD-II scanner to find specific trouble codes, then inspect the sensors and their wiring near each wheel for corrosion or damage.

Diagnosis and troubleshooting
- Use an OBD-II scanner: This is the best first step to identify the specific problem by reading the diagnostic trouble codes (DTCs).
- Inspect wheel speed sensors and wiring: Check the sensors and their harnesses for physical damage, corrosion, or loose connections, especially near the wheels.
- Check brake fluid: Ensure the brake fluid reservoir is at the correct level.
- Look for other related lights: If the brake, ESC, or TPMS lights are also on, it reinforces the possibility of a sensor or wiring issue affecting multiple systems.
What to do next
- Address the issue promptly: While the standard braking system will likely still function, the ABS system will not work during hard braking, which can be dangerous, especially in slippery conditions.
- Clean and repair: Clean any corroded connectors and repair or replace any damaged wiring or faulty sensors you find.
- Consider the ABS module: If the issue is not a sensor or wiring problem, the ABS control module may be failing. This is a more complex and expensive repair.
- Reset the light: After making repairs, you may need to use the scanner to clear the codes and reset the ABS light, or try disconnecting the battery to reset the system.
What is the lawsuit against the ABS module on a Ram 1500?
A new class action settlement will provide owners and lessees of certain model year Ram pickup trucks allegedly equipped with defective anti-lock braking systems (ABS) and faulty brake hydraulic control units with reimbursements for repairs and vehicle rentals, with automaker FCA US also agreeing to initiate a ...
Is there a way to tell which ABS sensor is bad?
You can tell which ABS sensor is bad by using a diagnostic scanner to read fault codes or check live data, or by manually testing the sensor with a multimeter. A scanner will show a specific code for a failing sensor or a live data feed where one wheel's speed reading is incorrect (like staying at 0 mph while the others move). A manual test involves checking the sensor's resistance or voltage output with a multimeter, which will be out of specification or inconsistent for a bad sensor.
Method 1: Using a diagnostic scanner
- Connect the scanner: Plug a compatible diagnostic scanner into your vehicle's OBD-II port.
- Read fault codes: Access the ABS or chassis control module and read the diagnostic trouble codes (DTCs). The code will often point to a specific wheel speed sensor that is malfunctioning.
- Check live data: Go to the "live data" or "data stream" option, specifically looking for wheel speed sensor readings (often labeled RPM sensors).
- Spin the wheels: While a friend watches the scanner, have them spin each wheel (or, if possible, drive the car slowly).
- Identify the faulty sensor: The sensor that shows a reading that is incorrect (e.g., stuck at 0 mph or an erratic number) is the one that is bad.
Method 2: Using a multimeter
- Locate the sensor and disconnect it: Follow the wire from the wheel to its connector and unplug it.
- Check for resistance:
- Set your multimeter to the "ohms" (Ωcap omegaΩ) setting.
- Connect the probes to the terminals on the harness side of the plug.
- You may need to use a specific tool or insert small wires to make contact if the terminals are deep.
- A good sensor will have a specific, steady resistance reading (often between 1.5 and 1.7 kiloohms, or 1500−1700 Ω1500 minus 1700 space cap omega1500−1700 Ω).
- If you get an "open" reading (OL) or a reading that is significantly different from your other sensors, the sensor is likely bad.
- Check for AC voltage:
- If the resistance test passes, set the multimeter to the AC voltage setting.
- Reconnect the sensor's wiring connector.
- Spin the wheel manually as fast as you can.
- A good sensor will generate a voltage reading that fluctuates with the speed of the wheel. If the voltage remains at 0 or doesn't change, the sensor is likely bad.
