Walker Products 350-34511 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. This Walker Products oxygen sensor is a direct-fit, narrow-band unit that gauges combustion efficiency from that oxygen reading.
- Monitors exhaust gases and helps reduce pollutants
- Electrodes with a gas-permeable platinum layer
- Coating on the electrode surfaces guards against contamination and erosion from combustion residue and particulates
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture to support fuel economy
Quick facts
- Part: Walker Products 350-34511 oxygen sensor
- Fits: 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 make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. These signs alone do not prove the sensor is at fault; a vacuum leak, for one, can also make an engine run poorly. With the engine off and cool, look the sensor, wiring harness and connector over for physical damage.
Fits
It is listed for a wide range of Dodge, Jeep, Chrysler and Plymouth models, including the 1995-2001 Dodge Ram 1500 V8 5.2L. It is also an oxygen sensor for the 1999-2000 Jeep Grand Cherokee 6-cylinder 4.0L and for the 1997 Jeep Wrangler with either the 4-cylinder 2.5L or the 6-cylinder 4.0L.

Frequently Asked Questions
Will this Ram 1500 oxygen sensor fit the 1995-2001 model with the V8 5.2L?
Yes, Walker Products 350-34511 is listed for the 1995-2001 Dodge Ram 1500 V8 5.2L, one sensor per vehicle. Check your own year and engine in the "Vehicles it fits" section.
Is this a Jeep Wrangler oxygen sensor replacement for 1997-2000 models with the 6-cylinder 4.0L?
Yes. Walker Products 350-34511 is listed for the 1997-2000 Jeep Wrangler 6-cylinder 4.0L, and for the 4-cylinder 2.5L in 1997-1998 and 2000.
Is this Walker oxygen sensor narrow-band or wideband?
Narrow-band. This oxygen sensor has four wires and electrodes with a gas-permeable platinum layer.
What signs can a worn narrow-band oxygen sensor show?
The engine can run poorly, fuel consumption and exhaust emissions can rise, or the malfunction indicator light can come on. Newer vehicles also store fault codes in the ECU, some tied to the sensor.
Does the Walker Products 350-34511 replace CTK-OSCH4006?
Yes. CTK-OSCH4006 is listed as an interchange number for the Walker Products 350-34511 oxygen sensor.
