Walker Products Oxygen Sensor P/N:350-31040
Walker Products 350-34554 oxygen sensor for the 1993-1998 Toyota Supra 6-cylinder 3.0L measures the oxygen in the exhaust gas to show how efficiently the engine is burning fuel. The Walker Products oxygen sensor works in the upstream position and gives the ECU the diagnostic feedback it needs.
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can be behind the same signs, so look both over for physical damage and find the cause before you buy a sensor.
The 1993-1998 Toyota Supra 6-cylinder 3.0L takes one upstream sensor, and this listing is one direct-fit sensor.

Is this the right Supra oxygen sensor for the 1993-1998 Toyota Supra 6-cylinder 3.0L?
Yes. Walker Products 350-34554 is a direct-fit upstream oxygen sensor for the 1993-1998 Toyota Supra 6-cylinder 3.0L, and that car takes one.
Is this 4-wire oxygen sensor narrow-band or wideband?
It is a narrow-band sensor with 4 wires and a flange mount. Walker Products 350-34554 has an M18 - 1.5 thread.
What does the coating on this oxygen sensor do?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.
Can a failed oxygen sensor turn on the malfunction indicator light?
Yes, a failed sensor can light the MIL, make the engine run poorly, or raise fuel use and emissions. A shop can read the stored fault codes to see which sensor or system is involved.
Why is this oxygen sensor made for one position?
Each Walker Products sensor number is made for a specific application and fitment position. It gives the ECU the diagnostic feedback that position calls for.
