Oxygen Sensor for 2000-2001 Nissan Sentra & More - Walker 350-34309

Walker Products 350-34309 oxygen sensor for the 2000-2001 Nissan Sentra 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. Every part number is made for its specific application and fitment position, and it returns the diagnostic feedback the ECU needs.

• Electrodes made of a gas-permeable platinum layer
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and exhaust particulates
• Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
• Monitors the exhaust air-fuel ratio for combustion efficiency
• Four-wire, narrow-band design

Quick facts

• Part: Walker Products 350-34309 oxygen sensor
• Fits: 2000-2001 Nissan Sentra 4-cylinder 1.8L and other vehicles
• Position: Center, downstream right, downstream front

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 this oxygen sensor is the problem, since a vacuum leak can also make an engine run poorly. With the engine off, check the sensor, wiring harness and connector for physical damage too.

Fits

It is a direct-fit oxygen sensor for the 2000-2001 Nissan Sentra 4-cylinder 1.8L, the 1998-2001 Nissan Maxima V6 3.0L and the 1999-2001 Infiniti I30 V6 3.0L. This listing is one sensor, and each of these cars needs just one.
