Walker Products 250-24494 oxygen sensor for the 1999-2002 Volkswagen Jetta V6 2.8L, the 2001-2005 Jetta 4-cylinder 1.8L and other vehicles measures the oxygen content of the exhaust gas. It monitors the air-fuel ratio so the ECU can see how efficiently combustion is running.
- Narrow-band sensor with 4 wires
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels to fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust
Quick facts
- Part: Walker Products 250-24494 oxygen sensor
- Fits: 1999-2002 Volkswagen Jetta V6 2.8L, the 2001-2005 Jetta 4-cylinder 1.8L and other vehicles
- Position: upstream, downstream, downstream left, downstream right, downstream front, downstream rear
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. Before you replace it, look the sensor, wiring harness and connector over for physical damage with the engine off, since damaged wiring is another place those symptoms can start.
Fits
It fits the 1999-2002 Volkswagen Jetta V6 2.8L and the 2001-2005 Jetta 4-cylinder 1.8L, and it is also an oxygen sensor for the 2002-2004 Volkswagen Passat W8 4.0L and the 1999 VW Golf 4-cylinder 2.0L. This listing is one sensor, and the quantity is one per vehicle. If your Volkswagen or Audi is not named here, open the "Vehicles it fits" section and check your exact model and engine.

Frequently Asked Questions
Is this oxygen sensor right for a 1999-2002 VW Jetta V6 2.8L?
Yes. Walker Products 250-24494 fits the 1999-2002 Volkswagen Jetta V6 2.8L. This listing is a single sensor.
Will this O2 sensor work on a 2001-2005 VW Jetta 4-cylinder 1.8L?
Yes. Walker Products 250-24494 fits the 2001-2005 Volkswagen Jetta 4-cylinder 1.8L. For any other model, open the "Vehicles it fits" section and check your engine there.
Is this a narrow-band or a wideband oxygen sensor?
This oxygen sensor is narrow-band and has 4 wires. It measures the oxygen content of the exhaust gas to monitor the air-fuel ratio.
Could a rough-running engine and a lit check engine light come from this oxygen sensor?
They can. A failed sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or light the malfunction indicator light. Newer vehicles store related fault codes in the ECU.
What does the coating on the electrodes of 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.
