2pc Oxygen Sensor Set For 2002-2003 Suzuki Aerio 2.0L – Upstream & Downstream, Heated, 4-Wire

Got a check engine light on your 2002-2003 Suzuki Aerio with the 2.0L engine?

Probably an oxygen sensor.

This Topcn-autoparts set includes both the upstream (front) and downstream (rear) sensors.

They're heated, 4-wire sensors with a blade terminal and M18 thread.

The hex size is 7/8 inch.

They're a direct replacement, just unplug the old ones and screw these in.

The output signal is narrow-band, 0.2 to 0.8 volts, just like the originals.

They come with a 1-year warranty.

If you've been dealing with poor mileage or a P0420 code, these sensors will sort it out.
