Does a 2009 Acura TSX have a power steering pump?
Yes. The 2009 Acura TSX uses a belt-driven hydraulic power steering system that includes a dedicated power steering pump, rather than an electric power-assisted setup.
System type and components
The 2009 TSX relies on a hydraulic power steering (HPS) system. The power steering pump is mounted on the engine and is driven by the serpentine belt. It circulates hydraulic fluid from a reservoir through hoses to the steering rack to provide assist when you turn the wheel. The system uses a dedicated power steering fluid (consult the owner's manual for the exact specification) rather than a generic ATF, and it is not an electric power-steering system.
Signs of trouble and maintenance
Common indicators that the power steering pump or hydraulic system may be failing include:
- Whining, groaning, or squealing noises when turning the wheel
- Stiff or heavy steering, especially at low speeds
- Fluid leaks around the pump, hoses, or reservoir
- Low power steering fluid level or foamy fluid in the reservoir
- Intermittent or reduced steering assist
If you notice any of these symptoms, have the system inspected by a qualified technician. Driving with a failing power steering pump can cause further damage and compromise steering control.
Ways to care for the hydraulic PS system and pump include:
- Check the power steering fluid level regularly (monthly or with routine maintenance) and top up with the correct fluid as specified in the owner's manual
- Inspect hoses and the reservoir for cracks, swelling, or leaks; replace worn components promptly
- Inspect the drive belt for wear or looseness and replace or adjust as needed
- If the pump or system is serviced, ensure the system is properly bled to remove air
- Use the manufacturer-recommended fluid type to avoid compatibility issues
Maintaining proper fluid levels, inspecting for leaks, and keeping the drive belt in good condition can help preserve steering assist and prevent costly repairs.
Electric vs hydraulic: Is EPS used in the 2009 TSX?
Clarification
The 2009 Acura TSX does not use electric power steering (EPS). It employs a traditional hydraulic power steering system with a belt-driven pump. Some newer or different-model Hondas and Acuras have shifted to EPS, but the TSX model year 2009 remains hydraulic unless modified or replaced with aftermarket components.
Summary
In summary, the 2009 Acura TSX does have a power steering pump as part of its hydraulic power steering system. If you experience noises, stiff steering, or fluid leaks, or if the fluid level is consistently low, schedule an inspection. Regular checks and proper fluid usage help maintain reliable steering assist and reduce the risk of pump failure.
