Walker Products Oxygen Sensor P/N:350-341002
Walker Products 350-31007 oxygen sensor for the 1987-1991 Toyota Camry 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. This Walker Products oxygen sensor is an upstream, narrow-band unit that mounts with a flange.
A failed sensor can make the engine run poorly, raise fuel consumption or emissions, or turn on the malfunction indicator light. A wiring harness or connector with physical damage can also make the engine run poorly, so look those over before you replace the sensor.
It also serves as an oxygen sensor for the 1985-1989 Toyota Corolla 4-cylinder 1.6L and the 1984-1987 Toyota 4Runner 4-cylinder 2.4L, among many other vehicles, with one sensor per vehicle.
