Walker Products 250-24011 oxygen sensor for the 1990-1997 Honda Accord 4-cylinder 2.2L and other vehicles measures the oxygen content of the exhaust gas. It is made for its specific application and fitment position, and it sends the ECU the diagnostic feedback it needs.
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Several faults can look alike, so with the engine off and cool, look the sensor, its wiring harness and its connector over for physical damage before you replace anything. This listing is one sensor, and the application list calls for one at the upstream position.
This is a direct-fit upstream oxygen sensor for the 1999-2000 Honda Civic 4-cylinder 1.6L and for the 1997-2001 Honda CR-V 4-cylinder 2.0L, along with many other Honda, Acura and Isuzu models. If your car is not named here, look up its year and engine on the Buyer's Guide tab.

The Walker Products 250-24011 is a 4-wire, narrow-band oxygen sensor.
What does the coating on this oxygen sensor protect?
The coating keeps combustion residue and particulates in the exhaust gases from contaminating or eroding the electrode surfaces of this sensor.
Is this oxygen sensor an upstream or a downstream unit?
It is an upstream oxygen sensor, and the application list calls for one per vehicle.
What does the Walker Products 250-24011 report to the ECU?
The Walker Products 250-24011 measures the oxygen content of the exhaust gas and monitors the air-fuel ratio, giving the ECU diagnostic feedback on combustion efficiency.
