Walker Products 250-24943 oxygen sensor for the 1997-1998 Jeep Wrangler 4-cylinder 2.5L, the 1997-2000 Wrangler 6-cylinder 4.0L, the 2000 Wrangler 4-cylinder 2.5L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is a direct-fit, narrow-band unit.
- Made for the specific application and fitment position, with the diagnostic feedback the ECU requires
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Gas-permeable platinum layer on the electrodes
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
Quick facts
- Part: Walker Products 250-24943 oxygen sensor
- Fits: the 1997-1998 Jeep Wrangler 4-cylinder 2.5L, the 1997-2000 Wrangler 6-cylinder 4.0L, the 2000 Wrangler 4-cylinder 2.5L and other vehicles
- Position: upstream, downstream, upstream left, upstream right, downstream left, downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. These signs alone do not point to the sensor, because a damaged wiring harness or connector can produce them too.
Fits
The fit includes the 1995-2001 Dodge Ram 1500 V6 3.9L or V8 5.2L, the 1996-2000 Ram 1500 V8 5.9L and the 1999-2000 Jeep Grand Cherokee 6-cylinder 4.0L, plus many other vehicles. It also works as a Jeep Wrangler oxygen sensor replacement for the 1997-1998 Wrangler 4-cylinder 2.5L, the 1997-2000 Wrangler 6-cylinder 4.0L and the 2000 Wrangler 4-cylinder 2.5L. This listing is one sensor, and the 1999-2000 Jeep Grand Cherokee 6-cylinder 4.0L takes one.

Frequently Asked Questions
Is this a Ram 1500 oxygen sensor for the 1995-2001 Dodge Ram 1500 V6 3.9L or V8 5.2L?
Yes. Walker Products 250-24943 fits the 1995-2001 Dodge Ram 1500 V6 3.9L or V8 5.2L and the 1996-2000 Ram 1500 V8 5.9L, and a Ram 1500 takes one.
Is this a Jeep Grand Cherokee oxygen sensor for the 1999-2000 Grand Cherokee 6-cylinder 4.0L?
Yes. Walker Products 250-24943 fits the 1999-2000 Jeep Grand Cherokee 6-cylinder 4.0L. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.
Is this oxygen sensor narrow-band or wideband?
This oxygen sensor is narrow-band with a direct-fit design, and its threaded body is M18 - 1.5.
What can a failing 250-24943 oxygen sensor cause?
Poor running, extra fuel use, higher emissions or a lit malfunction indicator light can be signs of one. Looking over the sensor, wiring harness and connector for physical damage is also worthwhile.
What does the coating on this oxygen sensor protect against?
The coating keeps combustion residue and particulates in the exhaust gases from contaminating and eroding the electrode surfaces.
