2014-2022 GMC Canyon Transmission Speed Sensor: A Replacement Guide
Solve erratic speedometer readings and harsh shifting by understanding your Canyon's speed sensor.
- An erratic speedometer and harsh, incorrect shifting are the most common signs of a failing transmission speed sensor in your Canyon.
- For shifting problems, first ask a dealer to check for transmission software updates (TSBs), as this can be a fix that doesn't require parts.
- The genuine GM/ACDelco replacement sensor (Part #24276628) is often cheaper and more reliable than aftermarket options for this vehicle.
- A bad sensor will likely trigger the Check Engine Light with codes such as P0722 or P0700.
Understanding Your Canyon's Speed Sensors
Your 2014-2022 GMC Canyon has two types of speed sensors. The one that causes problems with your speedometer and shifting is the Vehicle Speed Sensor (VSS), located on the transmission. The other type is the Wheel Speed Sensor (WSS), found at each wheel hub, which is for your ABS and traction control systems. This guide focuses on the transmission VSS, which is the part you likely need if your speedometer is acting up or your transmission is shifting poorly.
Symptoms of a Failing Transmission Speed Sensor
When the VSS starts to fail, it sends bad information to your truck's computer. This can cause several noticeable problems:
- Erratic or Dead Speedometer: The speedometer needle may jump around, read an incorrect speed, or not move at all.
- Harsh or Incorrect Shifting: Your automatic transmission may shift hard, delay its shifts, or seem to be in the wrong gear because it doesn't know how fast the truck is moving.
- Cruise Control Won't Work: The cruise control system relies on a steady speed signal from the VSS. If the signal is bad, cruise control will not engage.
- Check Engine Light: A failing VSS will almost always trigger the Check Engine Light. You may find codes like P0722 (Output Speed Sensor Circuit No Signal) or P0700 🎬 Watch: Understanding the causes and fixes for the P0722 code. (Transmission Control System Malfunction).
Shifting Problems? Check for Software Updates First
Some 2014-2022 Canyon models have known issues with harsh shifting or gear hunting that are not caused by a bad sensor. GM has released Technical Service Bulletins (TSBs) to address these problems with a transmission software update. Before you spend money on a new sensor to fix a shifting issue, it's worth asking a dealership to check if any transmission-related TSBs apply to your truck. A simple software re-flash could be the solution.

When it's time to replace your sensor, you have a few options. For this specific part on the Canyon, the choice is surprisingly clear.
OEM (ACDelco): The original GM and ACDelco part is the most recommended choice. It is engineered for your vehicle and, in a rare exception, is often significantly cheaper than aftermarket alternatives, with prices found online for as low as $25-$40. Given the low cost and perfect compatibility, this is the smartest option.
Premium Aftermarket (Delphi): Delphi is often an original equipment manufacturer for many brands. Their parts are considered a top-tier alternative to the dealer part, offering similar quality and reliability. If you can't source an ACDelco part, Delphi is a solid second choice.
Standard Aftermarket (Standard Ignition, Holstein): Brands like Standard Motor Products (Standard Ignition) and Holstein offer reliable parts that meet or exceed original specifications. They are dependable choices that fit a wide range of budgets and are readily available.
Pro Tip: Check the OEM Price First
Always check the price of the genuine GM/ACDelco sensor (Part No. 24276628) before buying an aftermarket part. You will likely find the original part is the most affordable and reliable option, which is unusual for auto parts.
| Part Type | Estimated Cost |
|---|---|
| New OEM (ACDelco) | $25 - $40 |
| New Aftermarket | $50 - $83 |
| Shop Labor | $50 - $100 |
