HTMXJA Oxygen O2 Sensor Kit for 2005-2006 Honda CR-V L4 2.4L — 2-Piece Upstream & Downstream, Direct-Fit Replacement

HTMXJA 2-piece upstream and downstream oxygen sensor kit replaces OE#250-241123 / 250-54046 to restore accurate air-fuel sensing on 2005–2006 Honda CR-V L4 2.4L engines.

If your CR-V is showing reduced fuel efficiency, rough idle, or a check engine light tied to oxygen sensor codes, this matched pair from HTMXJA is engineered as a direct-fit replacement for the factory sensors. Each sensor monitors exhaust oxygen levels and sends voltage signals to the engine control unit so it can adjust fuel delivery and maintain proper combustion. These sensors are manufactured from corrosion-resistant materials and come as an upstream (pre-catalytic converter) and downstream (post-catalytic converter) set to ensure the vehicle’s emission control and fuel-trim systems operate correctly.

How will swapping these sensors affect fuel economy and engine behavior?

Replacing aged or failing oxygen sensors helps the engine computer get accurate air-fuel information, which can restore lost miles per gallon and smooth out idling. You may notice steadier throttle response and fewer surges as the fuel trim returns to proper ranges.

• Restores correct air-fuel ratio feedback to the ECU
• Helps reduce rough idle and hesitations caused by faulty readings
• Can improve MPG when sensors were driving rich or lean conditions

Are these sensors a direct fit for my 2005–2006 Honda CR-V L4 2.4L?

Yes — this HTMXJA kit is specified for 2005–2006 CR-V models with the 2.4L inline‑4 engine and matches the listed OE numbers. Always verify part compatibility with your vehicle by comparing OE numbers and connector style before installation.

• Fitment: 2005–2006 Honda CR-V L4 2.4L
• Reference/OE numbers: 250-241123, 250241123, 250-54046, 25054046
• Direct electrical connector and threaded bung for hassle-free replacement

What should I expect during installation and maintenance?

Installation is straightforward for technicians and competent DIYers: disconnect the vehicle battery, unplug the sensor connector, remove the old sensor with a high‑quality oxygen sensor socket, and torque the new sensor to factory spec. No additional programming is typically needed; codes should clear after the ECU adapts to the new sensors.

• Simple bolt‑in replacement using standard oxygen sensor tools
• Ship‑ready with pre-wired connector and heat‑resistant lead
• Allow ECU relearn time — drive cycle may be required to stabilize readings

What warranty and support come with the HTMXJA sensor pair?

HTMXJA backs these oxygen sensors with a six-month warranty and customer support to help confirm fitment or resolve product issues. If you encounter concerns, reach out to the seller for troubleshooting and return guidance within the warranty period.

• Six-month limited warranty coverage
• Customer support response within 24 hours
• Refund or replacement handled per seller policy when fitment or quality issues arise

Who is this for: This 2-piece HTMXJA oxygen sensor set is designed for owners and mechanics of 2005–2006 Honda CR-Vs with the 2.4L L4 engine who need a reliable, direct-fit upstream and downstream replacement. It suits drivers troubleshooting emission codes, technicians performing exhaust system repairs, and DIY enthusiasts wanting an OE-number matched sensor pair to restore proper fuel management and emission monitoring.
