Review TRQ Acura Oxygen Sensor Downstream fits TSX 2009–2014

The 12475CXTS oxygen sensor is a crucial component in the exhaust system of select Acura Tsx models produced between 2009 and 2014. Specifically, this sensor is suitable for the downstream position in vehicles from the years 2010, 2011, 2012, and 2013.

This oxygen sensor, manufactured by Dorman, is designed to accurately measure the amount of unburnt oxygen in the exhaust gases that leave the engine. This data is then sent to the vehicle's engine control unit (ECU) to optimize the fuel-air mixture for efficient combustion. By ensuring the correct balance of fuel and air is being used, the 12475CXTS oxygen sensor helps in reducing harmful emissions, improving fuel economy, and enhancing overall engine performance.

The 12475CXTS oxygen sensor comes as a complete assembly, including the sensor body, heating element, and the wiring harness. This OEM-quality replacement part is engineered to meet or exceed the original equipment specifications and is backed by Dorman's limited lifetime warranty, offering peace of mind to customers.

Installing the 12475CXTS oxygen sensor is a straightforward process, typically taking less than an hour for experienced DIYers or professional technicians. The sensor is located near the catalytic converter in the exhaust system, and the replacement process involves removing the old sensor, connecting the new wiring harness, and securing the new sensor in place with the provided clamps.

By choosing the 12475CXTS oxygen sensor for your Acura Tsx, you can restore the accuracy and efficiency of your vehicle's exhaust system, ensuring optimal engine performance and longevity.

Buying a new oxygen sensor (12475CXT) for a 2009-2014 Acura Tsx, specifically for the downstream position, can be a necessary expense for maintaining optimal engine performance. Here are some pros and cons to consider before making a purchase:

1. Improved Fuel Efficiency: A faulty oxygen sensor can cause the engine to run rich or lean, leading to poor fuel economy. Replacing the sensor can help restore optimal fuel efficiency.

2. Better Engine Performance: A faulty oxygen sensor can affect engine performance by causing misfires, rough idling, and poor acceleration. Replacing the sensor can help restore smooth and reliable engine performance.

3. Longer Engine Life: A faulty oxygen sensor can lead to long-term engine damage if left unaddressed. Replacing the sensor can help prevent costly engine repairs down the line.

4. Check Engine Light: A faulty oxygen sensor can cause the check engine light to come on. Replacing the sensor can help turn off the light and prevent unnecessary worry.

1. Cost: Replacing an oxygen sensor can be an expensive repair, especially if you choose to have it done at a dealership or repair shop. The part itself may cost around $50-$100, but labor costs can add significantly to the total cost.

2. Time: Replacing an oxygen sensor can be a time-consuming process, especially if you choose to do it yourself. You will need to purchase the necessary tools and equipment, as well as spend time removing the old sensor and installing the new one.

3. DIY Difficulty: Some people may find it challenging to replace an oxygen sensor themselves, especially if they are not mechanically inclined. The process involves removing the old sensor, connecting the new one, and calibrating the engine control system.

Replacing an oxygen sensor (12475CXT) in a 2009-2014 Acura Tsx can be a necessary expense to maintain optimal engine performance and prevent long-term engine damage. While the cost and time involved can be a deterrent, the benefits of improved fuel efficiency, better engine performance, and longer engine life make it a worthwhile investment. If you are comfortable working on your own car, consider doing it yourself to save on labor costs. Otherwise, consider having it done at a reputable repair shop.
