Walker Products 350-33077 oxygen sensor for the 1997-1998 Aston Martin DB7 6-cylinder 3.2L and other vehicles measures combustion efficiency from exhaust oxygen. Built for its specific application and position, this Walker Products oxygen sensor gives the ECU the diagnostic feedback it needs.
- Reads the oxygen content of the exhaust gas to monitor the air-fuel ratio
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Electrodes made of a gas-permeable platinum layer
- Monitoring of the exhaust gases helps reduce pollutants
Quick facts
- Part: Walker Products 350-33077 oxygen sensor
- Fits: 1997-1998 Aston Martin DB7 6-cylinder 3.2L and other vehicles
- Position: Upstream, upstream left, upstream right
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. Before you replace the sensor, rule out physical damage to its wiring harness and connector; if the sensor itself is the cause, this one replaces it.
Fits
The 1997-1998 Aston Martin DB7 6-cylinder 3.2L, the 1996-1997 Audi S6 5-cylinder 2.2L and the 1993-1994 Jaguar XJS 6-cylinder 4.0L, plus the 1994 XJS V12 6.0L, are among the cars this sensor fits, and each takes a single sensor. This listing is one sensor. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is 350-33077 the S6 oxygen sensor for a 1996-1997 Audi S6 5-cylinder 2.2L?
Yes. Walker Products 350-33077 fits the 1996-1997 Audi S6 5-cylinder 2.2L, and that car takes one sensor.
Is this a Jaguar XJS oxygen sensor for the 1993-1994 6-cylinder 4.0L and the 1994 V12 6.0L?
Yes. Walker Products 350-33077 fits the 1993-1994 XJS 6-cylinder 4.0L and the 1994 XJS V12 6.0L, and each takes one sensor.
Is 350-33077 a narrow-band oxygen sensor?
Yes. This oxygen sensor is a narrow-band type with 3 wires and a direct fit.
What can a failing upstream oxygen sensor cause?
A failing oxygen sensor can lead to rough running, higher fuel consumption or a lit malfunction indicator light. Newer vehicles may also store a related fault code in the ECU, which a shop can read.
What does the coating on this oxygen sensor protect?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.
