Walker Products Oxygen Sensor P/N:250-241242
Walker Products 250-24617 oxygen sensor for the 1997-1999 Chevrolet Malibu 4-cylinder 2.4L, the 1997-2003 Malibu V6 3.1L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine is burning fuel. This listing is one sensor.
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since a vacuum leak can also make an engine run poorly. The sensor, wiring harness and connector can also be inspected for physical damage.
This sensor is listed for Chevrolet, Oldsmobile and Pontiac models, including the 1999-2001 Oldsmobile Alero 4-cylinder 2.4L, the 1999-2004 Alero V6 3.4L, the 1999-2001 Pontiac Grand Am 4-cylinder 2.4L and the 1999-2004 Grand Am V6 3.4L. It is a direct-fit replacement for these vehicles, and the 1997-2003 Malibu V6 3.1L takes one. If your car is not named here, open the Buyer's Guide tab and look up your exact model and engine.

Is this Walker Products oxygen sensor narrow-band or wideband?
This sensor is a narrow-band design with 4 wires and an M18 - 1.5 thread. It determines the oxygen content of the exhaust gas and monitors the air-fuel ratio.
Which symptoms can point to a failing narrow-band oxygen sensor?
Rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Newer vehicles may also store fault codes related to the sensor.
What does the coating on this oxygen sensor protect against?
The coating keeps combustion residue and particulates in the exhaust gases from contaminating or eroding the electrode surfaces. The electrodes themselves are a gas-permeable platinum layer.
