TRQ O2 Oxygen Sensor 4-Wire

Key specifications

The defining detail here is the combination of a four-wire, wide-band planar design and an upstream position. TRQ lists this sensor for specific four-cylinder Honda applications: the 2006–2015 Civic with a 1.8L engine, the 2014–2015 Accord with a 2.0L engine, and the 2016–2022 HR-V with a 1.8L engine. Those year and engine details matter, a model name alone is not enough to confirm fit.

The listing describes it as a preassembled direct replacement intended to install without modifications. That can make it a more straightforward repair choice than sourcing a less-specific part, but the description doesn’t provide wire length or connector dimensions. You can’t judge routing reach from the listed details without that measurement. Reference numbers are also supplied, which can help when matching an existing part, but they should be checked against the exact vehicle application.

Who it’s for

This sensor is aimed at owners or repair professionals replacing the upstream sensor on one of the listed Honda engine and model-year combinations. It makes sense if you’ve already identified the upstream position and can match your vehicle’s year, model, engine, and existing part reference. For instance, while preparing a repair, compare the number on the removed sensor with the references in the listing before ordering rather than relying on “Civic” or “HR-V” alone.

TRQ also describes a library of DIY replacement-part videos, which may be useful if you prefer to watch a repair walkthrough before starting. That is a general resource, not confirmation that a video for your exact vehicle and repair is available. You may want to skip it if your vehicle or engine falls outside the applications listed, or if you need installation details such as cable reach before deciding.

Everyday use

The product is a replacement component, not a general-purpose accessory. Its value depends on matching the specified upstream application, choosing a sensor for the wrong position or engine would defeat the point of a direct-fit design. The listed preassembled setup is intended to avoid modifications, but that wording doesn’t replace a vehicle-specific fit check. Confirm the full compatibility chart and compare reference numbers before purchase, especially if your model year sits near the edge of a listed range.

Questions before you buy

Does it fit every Honda Civic, Accord, or HR-V? No. The listing names particular year and engine combinations, not every version of those models. Match your exact application to the compatibility chart.

Is it an upstream sensor? Yes. The product is identified as an upstream, wide-band planar O2 sensor.

What warranty is listed? TRQ states a limited lifetime warranty against defects in materials and workmanship when the part is used as intended. Normal wear and tear, misuse, abuse, and unauthorized modification are excluded.

Final verdict

This TRQ sensor is worth considering when your vehicle matches one of the listed applications and you’re replacing that specific upstream part. The four-wire design, reference numbers, and stated direct-replacement intent give you useful points to cross-check, while TRQ’s DIY video library may support a hands-on repair. The main reason to hold off is uncertainty about fit or installation details: confirm the exact engine and year, and don’t assume the model name by itself guarantees compatibility.
