Is a 2009 Acura TSX VTEC?
Yes. The 2009 Acura TSX uses Honda’s i-VTEC 2.4-liter inline-four engine, which employs VTEC on the intake cam to vary valve timing for improved performance and efficiency. In other words, the 2009 TSX is a VTEC-powered model, though it’s not the higher-performance TSX Type-S variant.
Engine technology and specs
The 2009 TSX relies on a refined K-series engine that balanced everyday drivability with responsive performance. Here are the key technical details you should know:
- Engine code: K24Z3
- Displacement: 2.4 L (2354 cc)
- Configuration: Inline-4, DOHC
- Valvetrain: i-VTEC on the intake cam (VTEC engaged for higher RPMs) with timing adjustments via VVT
- Power output: approximately 201 horsepower
- Torque: approximately 172 lb-ft
- Transmission options: 6-speed manual or 5-speed automatic with Sequential SportShift
- Drivetrain: Front-wheel drive
In summary, the 2009 TSX uses a 2.4-liter i-VTEC engine with intake-cam VTEC that activates at higher RPMs for extra power, while maintaining smooth, efficient operation for daily driving.
How VTEC works in the TSX and what buyers should know
The i-VTEC system in the 2009 TSX blends variable valve timing with a VTEC switch on the intake cam. At lower RPMs, the engine uses a gentler cam profile for efficiency; as engine speed rises, the system switches to a higher-lift, longer-duration profile for more power and responsiveness. This design aims to provide both practical fuel economy and stronger acceleration when you push the pedal.
When shopping for a used TSX
For buyers considering a 2009 TSX, certain checks can help confirm the vehicle’s condition and that the VTEC system is functioning properly. The following items are commonly reviewed:
- Engine start and idle: Smooth idle with no roughness or misfires
- VTEC engagement: Audible or feel of power increase as RPMs climb past the VTEC activation point
- Valve cover and oil leaks: Inspect for seepage around the gasket
- Timing chain and tensioners: Listen for faint rattle or noise from the timing area, especially with high-mileage examples
- Maintenance history: Regular oil changes with suitable oil and documented service intervals
Regular maintenance and timely service are important for the long-term reliability of the TSX’s i-VTEC system. A well-kept example can remain a solid, engaging sedan for years.
Buying considerations and common questions
When evaluating a 2009 TSX, consider how you’ll use the car, the availability of a good maintenance history, and the condition of the drivetrain and transmission. The i-VTEC setup is robust when properly maintained, but as with any aging vehicle, seek a thorough inspection and a maintenance record.
Pros and Cons
Below are some commonly cited advantages and potential drawbacks to weigh when considering a used 2009 TSX:
- Pros: Smooth, refined power delivery; reliable K-series engine with proper maintenance; balanced ride and handling for a midsize sedan; available manual transmission for engaging driving.
- Cons: Age-related wear on suspension components and bushings; potential for higher mileage typical of a 2009 model; maintenance costs can accrue if the car hasn’t been well cared for.
In short, a 2009 TSX with a solid maintenance history offers a compelling blend of VTEC-era engineering and everyday practicality, provided you verify its service records and condition.
Summary
The 2009 Acura TSX is a VTEC-powered sedan built around Honda’s 2.4-liter i-VTEC inline-four. It produces about 201 hp and 172 lb-ft of torque, with a choice of a 6-speed manual or a 5-speed automatic transmission, and front-wheel drive. It represents a well-rounded option for buyers seeking reliable performance, comfortable daily driving, and the distinct efficiency/driveability benefits of VTEC technology in a traditional mid-size sedan.

Is a 2009 Acura TSX fast?
"The car is certainly quick -- around 6.5 seconds to 60 mph -- but you really have to wring the tachometer to get it moving.Fine for a Civic, OK for an Accord, but lacking in that gratifying quality of effortlessness that luxury cars have, even entry-luxury cars."
