Walker Products 250-24345 oxygen sensor for the 2001-2002 Jeep Wrangler 4-cylinder 2.5L, the 2001-2004 Wrangler 6-cylinder 4.0L, the 2003-2004 Wrangler 4-cylinder 2.4L and other vehicles measures the oxygen left in the exhaust gas. The Walker Products oxygen sensor is a 4-wire, direct-fit, narrow-band design that gives the ECU the diagnostic feedback it needs for its application.
- Electrodes with a gas-permeable platinum layer
- Coating that protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Monitors exhaust gases to help reduce pollutants
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
Quick facts
- Part: Walker Products 250-24345 oxygen sensor
- Fits: 2001-2002 Jeep Wrangler 4-cylinder 2.5L, the 2001-2004 Wrangler 6-cylinder 4.0L, the 2003-2004 Wrangler 4-cylinder 2.4L and other vehicles
- Position: upstream, downstream, upstream left, upstream right, downstream left, downstream right
- Condition: New
A worn sensor can show up as a rough-running engine, higher fuel consumption, higher exhaust emissions or a lit malfunction indicator light, though a damaged wiring harness or connector can be behind the same signs, so look both over for physical damage before you replace the sensor. This listing is one sensor, and each application in the fitment takes one.
Fits
The 2001-2003 Jeep Grand Cherokee 6-cylinder 4.0L fits this oxygen sensor, and so do many other vehicles. It is also an oxygen sensor replacement for the 2001-2004 Jeep Wrangler 6-cylinder 4.0L. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this O2 sensor for the 2001-2004 Jeep Wrangler 6-cylinder 4.0L?
Yes. Walker Products 250-24345 is listed for the 2001-2004 Jeep Wrangler 6-cylinder 4.0L. Open the "Vehicles it fits" section to check another model or engine.
Is this an oxygen sensor for the 2004-2006 Dodge Ram 1500 V10 8.3L?
Yes. Walker Products 250-24345 is listed for the 2004-2006 Dodge Ram 1500 V10 8.3L, and that application takes one sensor.
Is this oxygen sensor narrow-band or wideband?
It is narrow-band, with 4 wires and an M18 - 1.5 thread.
How can I tell whether this oxygen sensor is the problem?
Newer vehicles store fault codes in the ECU, and some relate to the sensor and its systems. A shop can read those codes for you.
What does the platinum coating on this oxygen sensor do?
The electrodes carry a gas-permeable platinum layer. The coating keeps combustion residue and particulates in the exhaust gases from contaminating or eroding the electrode surfaces.
