Walker Products 350-34602 oxygen sensor for the 2001-2004 Ford Escape 4-cylinder 2.0L and other vehicles measures oxygen in the exhaust gas. This Walker Products oxygen sensor is made for its specific application and position, and it sends 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 particulates in the exhaust gas
- Monitors exhaust gases to help reduce pollutants
- Measures oxygen levels to help fine-tune the air-fuel mixture for fuel economy
- Narrow-band sensor with 4 wires
Quick facts
- Part: Walker Products 350-34602 oxygen sensor
- Fits: 2001-2004 Ford Escape 4-cylinder 2.0L and other vehicles
- Position: Downstream, upstream left, upstream right, downstream left, downstream right
- Condition: New
A failing sensor can bring rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light, and newer vehicles store related fault codes in the ECU. Before you replace it, rule out physical damage to the wiring harness and connector by looking them over.
Fits
The 2001-2004 Ford Escape 4-cylinder 2.0L and the 1996-2000 Ford Explorer V6 4.0L take this direct-fit oxygen sensor, and so do many other vehicles. It also serves as a Ford Ranger oxygen sensor on the 1995-2000 V6 4.0L, the 1995-2003 V6 3.0L and the 2004-2005 V6 4.0L. The fitment lists one sensor for each sensor position, and this listing is a single sensor.
