Prices for a Q50 speed sensor vary by sensor type and source. The part itself typically costs about $40–$260; labor to install can push the total to roughly $150–$600 depending on the sensor and shop.
What the sensor does and where it’s used
In the Infiniti Q50, you may encounter two main speed-sensing devices: the vehicle speed sensor (VSS) inside the transmission, which reports overall vehicle speed to the engine/ transmission control modules, and wheel speed sensors at the wheels, which feed the ABS/traction control system. A faulty sensor can affect the speedometer reading, shifting behavior, and warning lights, making it important to identify the correct part before purchasing.
Price ranges by sensor type
Prices depend on whether you’re buying a transmission VSS or a wheel-speed/ABS sensor, and whether you choose OEM or aftermarket parts. The ranges below reflect common prices today across retailers.
- Vehicle speed sensor (VSS) for Infiniti Q50: typically $120–$260 for a new part; aftermarket options are often $60–$150; dealer/OEM pricing tends to be higher.
- Wheel speed sensor (ABS sensor) per wheel: commonly $40–$140 new or rebuilt; aftermarket brands may run $60–$180; OEM sensors can be higher.
- Transmission sensor kit or bundled speed sensors: about $100–$300 for aftermarket kits; OEM kits can exceed this amount.
Bottom line: The exact price depends on sensor type, model year, and retailer. Always verify compatibility with your Q50’s VIN before purchase.
Where to buy and how to choose
Shop options include new OEM parts from Infiniti dealers, reputable aftermarket brands, or used parts from salvage yards. Each option has trade-offs in price, warranty, and lifespan.
- OEM/Dealer parts: Highest price but best fit and warranty assurances.
- Aftermarket brands (Dorman, Bosch, Valeo, etc.): Balanced price and reliability; check part numbers and reviews.
- Used/Salvage parts: Lowest upfront cost but potentially limited life and no warranty; verify return policies.
To reduce risk, confirm the exact part number for your vehicle’s year and trim. If you’re unsure which sensor your Q50 needs, consult a mechanic or check for related fault codes (speedometer, ABS alerts, etc.).
Labor costs and installation considerations
Labor costs vary by sensor location and local rates. Replacing a wheel-speed sensor is generally quicker (roughly 0.5–1.5 hours), while a transmission VSS replacement can take 2–4 hours due to access. Expect labor rates around $70–$150 per hour, with total installation often adding $100–$350 on top of parts, depending on the market and shop.
Summary
For a Q50, expect the part itself to range from about $40 to $260 depending on sensor type and supplier, with OEM parts typically at the higher end. Labor adds to the total, so the complete outlay is usually in the hundreds of dollars. Always confirm the correct sensor type and part number for your year/model, and consider getting multiple price quotes to lock in the best deal.
