Walker Products Oxygen Sensor P/N:350-34354
Walker Products 350-34536 oxygen sensor for the 1995-1997 Toyota Land Cruiser 6-cylinder 4.5L and other vehicles measures combustion efficiency from the amount of oxygen in the exhaust gas. It is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it requires.
Rough running, higher fuel consumption or a lit malfunction indicator light can be signs of a worn sensor. Those signs alone do not prove it is the culprit, since a vacuum leak can also make an engine run poorly.
This upstream oxygen sensor is a direct-fit replacement for the 1995-1997 Toyota Land Cruiser 6-cylinder 4.5L and the 1996-1997 Lexus LX450 6-cylinder 4.5L. This listing is one sensor; the Toyota takes one, as does the Lexus.
