Common Symptoms of a Faulty Speed Sensor
A malfunctioning speed sensor can cause a variety of issues that affect the overall performance and safety of your 2014 Honda Accord. Recognizing these symptoms early can help you avoid more serious mechanical problems.
One of the most noticeable symptoms is erratic or non-functional speedometer readings. Since the speed sensor transmits vehicle speed data to the instrument cluster, any failure can cause the speedometer to behave unpredictably or stop working altogether. This can lead to difficulty maintaining appropriate speeds and may result in speeding violations.
Transmission shifting problems are another common sign. The speed sensor provides input to the transmission control unit, influencing shift timing and smoothness. A faulty sensor can cause harsh shifting, delayed gear changes, or the transmission to get stuck in a particular gear.
Additional symptoms include:
- Cruise control failure: The cruise control system relies on accurate speed data, so a bad sensor can disable this feature.
- Check Engine Light (CEL): The vehicle’s onboard diagnostics (OBD-II) system may detect the sensor malfunction and trigger the CEL.
- Poor fuel economy: Incorrect speed readings can affect engine management and fuel injection timing, leading to increased fuel consumption.
- ABS warning light activation: Since the speed sensor also contributes to wheel speed monitoring, its failure may cause ABS-related warnings.
Tools and Equipment Needed for Sensor Inspection and Replacement
To properly inspect and replace the speed sensor on a 2014 Honda Accord, having the right tools and equipment is essential. This ensures the job is done safely and efficiently.
Essential tools include:
- Socket set: A variety of metric sockets for removing bolts and sensor mounts.
- Ratchet wrench: For loosening and tightening fasteners.
- Torque wrench: To ensure bolts are tightened to manufacturer specifications.
- Screwdrivers: Both flathead and Phillips for connectors and clips.
- Jack and jack stands: To safely elevate the vehicle for undercarriage access.
- OBD-II scanner: For diagnosing sensor faults and resetting error codes.
- Multimeter: To test electrical continuity and sensor output.
- Replacement speed sensor: OEM or high-quality aftermarket parts recommended.

Location of the Speed Sensor on a 2014 Honda Accord
The 2014 Honda Accord utilizes multiple speed sensors to monitor vehicle speed and transmission operation. Understanding the exact location of the speed sensors is crucial for diagnostics, repairs, or replacements.
There are two primary speed sensors relevant to the 2014 Honda Accord:
- Vehicle Speed Sensor (VSS) – Monitors the speed of the vehicle for the engine control unit (ECU) and speedometer.
- Transmission Speed Sensor – Measures the rotational speed of the transmission components, often split into input and output speed sensors depending on the transmission design.
This section focuses on the second speed sensor, commonly referred to as the transmission output speed sensor or simply the secondary speed sensor.
Transmission Output Speed Sensor Location
On the 2014 Honda Accord, the second speed sensor is typically located on the transmission housing. It detects the rotational speed of the transmission output shaft, which helps the vehicle’s computer manage shifting patterns and torque converter lock-up.
| Component | Location | Access Notes |
|---|---|---|
| Transmission Output Speed Sensor | Mounted on the side or rear of the transmission case, near the driveshaft yoke | Requires vehicle lift or jack stands for undercarriage access; sensor is secured with a small bolt and connected by a two-pin electrical connector |
Visual Identification and Removal Tips
The transmission output speed sensor is a small cylindrical component with a protruding sensor tip that reads a tone ring or gear teeth on the transmission shaft. It usually has a plastic housing and a wiring harness with a clip connector.
- Locate the sensor by tracing the wiring harness from the transmission towards the driveshaft area underneath the vehicle.
- Look for a sensor mounted flush against the transmission housing, often secured by a single bolt.
- Disconnect the electrical connector carefully by pressing the release tab to avoid damaging the wires.
- Remove the mounting bolt with a suitable socket or wrench, then gently pull the sensor straight out.
