Autodayplus Upstream O2 Oxygen Sensor For 2001-04 Nissan Altima 3.5L & Frontier 2.4L | Direct Fit Heated Sensor

Got a check engine light on your 2001-04 Nissan Altima with the 3.5L V6 or a Frontier with the 2.4L?

It might be that upstream oxygen sensor going bad.

This Autodayplus sensor is a direct, plug-and-play replacement.

It's a heated sensor with three wires, so it starts reading accurately faster, which means better fuel economy and lower emissions.

The thread size is M18*1.5, and it comes with a blue plug.

It's a specific fit, not some universal junk you have to splice in.

Just screw it in and plug it up.

Swaps right in for part numbers like 234-3113 and 15951.

Comes with a 1-year warranty.

Get that engine light off and your Nissan running right again.
