Acura TL Vehicle Speed Sensor Guide for 2010-2014 Models
Experiencing erratic shifting or a faulty speedometer? Your Vehicle Speed Sensor might be the culprit.
- Verify your specific part number before buying; FWD and SH-AWD models may use different sensors with very different prices.
- A faulty VSS most commonly causes harsh, erratic transmission shifting, which can damage the transmission over time.
- A quality aftermarket sensor from a brand like Delphi or Standard Ignition is a reliable and cost-effective alternative to the OEM part.
- A P0722 diagnostic trouble code is a strong indicator of a failed vehicle speed sensor or its wiring.
Is Your Acura TL Vehicle Speed Sensor Failing?
When a Vehicle Speed Sensor (VSS) starts to go bad in your Acura TL, the signs are often related to the automatic transmission's performance before the speedometer even acts up. Because this sensor's data is so important for multiple systems, a failure can cause a variety of problems. Ignoring these symptoms can lead to more stress on your transmission and unsafe driving conditions.
Common Symptoms of a Bad VSS
- Harsh or Delayed Shifting: The most common symptom is the transmission shifting hard, late, or at the wrong times.
- Erratic Speedometer: The speedometer needle may jump around, show the wrong speed, or stop working completely.
- Cruise Control Failure: The cruise control system will not engage or will shut off unexpectedly because it needs a steady speed signal to function.
- Check Engine Light: A faulty VSS will almost always trigger the Check Engine Light, storing trouble codes like P0722.
- ABS/Traction Control Lights: In some cases, issues with the VSS can cause the Anti-lock Brake System (ABS) or Vehicle Stability Assist (VSA) lights to come on.
Important: Check Your Part Number
The 2010-2014 Acura TL may use different speed sensors depending on the transmission (FWD vs. SH-AWD). The two most common OEM part numbers are 28820-PWR-013 and 28810-R90-003 (or its successor 28810-R90-013). There is a significant cost difference between them. Always verify the correct part number for your specific vehicle's VIN before ordering.
Choosing the Right Aftermarket Speed Sensor
You don't need to buy an expensive OEM sensor from the dealer. Quality aftermarket brands offer reliable performance for a fraction of the price. Here’s how the available brands stack up.
Brand Quality Tiers
- Tier 1 - OE Quality Aftermarket (Delphi): Delphi is a major OE manufacturer for many car brands. Choosing a Delphi sensor is the closest you can get to the original part's quality and performance, often because they made the original part. They are known for robust testing and durability.
- Tier 2 - Reputable Aftermarket (Standard Ignition, Walker Products): Brands like Standard Ignition (also known as SMP) and Walker Products are well-respected in the aftermarket. They engineer their parts to meet or exceed OEM specifications and have a long history of producing reliable engine management components. These are a solid, dependable choice for most repairs.
- Tier 3 - Economy (Vemo): Vemo is a brand that often provides a budget-friendly option. While they can be a good value, they are not as widely reviewed by professional mechanics or Acura owner communities as Delphi or Standard. They are best for owners on a tight budget who need to get their car back on the road.
Cost of Replacing Your Vehicle Speed Sensor
The cost to replace a VSS is reasonable, especially if you do it yourself. The part itself is not expensive, and labor is minimal.
| Item | Estimated Cost |
|---|---|
| New OEM Part | $40 - $175 |
| New Aftermarket Part | $31 - $106 |
| Shop Labor | $75 - $125 |
| Total Professional Replacement | $106 - $231 |
DIY Replacement
Replacing the VSS on a 2010-2014 TL is a DIY-friendly job for most home mechanics. The sensor is located on the outside of the transmission and is typically held in by a single 10mm bolt. The job involves safely lifting the vehicle, unplugging the electrical connector, removing the bolt, swapping the sensor, and reassembling. The entire process usually takes less than an hour.
Frequently Asked Questions
Can I drive with a bad vehicle speed sensor?
You can, but it's not recommended for long. The unpredictable shifting can be dangerous in traffic and puts extra wear on your transmission's internal components. It's best to get it replaced as soon as possible.
Is a Vehicle Speed Sensor the same as an ABS sensor?
No. While both measure speed, they have different jobs. The Vehicle Speed Sensor (VSS) measures transmission speed for shifting and the speedometer. ABS (or wheel speed) sensors are located at each wheel and measure individual wheel rotation for the anti-lock braking and stability control systems.
How many speed sensors does my Acura TL have?
Your Acura's automatic transmission has at least two main speed sensors: an input shaft speed sensor and an output shaft speed sensor (the VSS). This article focuses on the output sensor, which is the most common one to fail and cause shifting issues. Your car also has four additional wheel speed sensors for the ABS system.
What does the code P0722 mean?
P0722 stands for "Output Speed Sensor Circuit No Signal." It means the car's computer is not receiving any signal from the VSS. This could be due to a failed sensor, a damaged wire, or a bad connection. This code is a strong indicator that the VSS needs to be inspected and likely replaced.
Technical Specifications
OEM Part Numbers: 28820-PWR-013 28810-R90-003 28810-R90-013
Typically a 2-pin or 3-pin magnetic sensor that mounts to the transmission case with a single bolt. Generates a pulse signal that corresponds to the output shaft's rotational speed.
