O2 Oxygen Exhaust Sensor For Vauxhall Astra Zafira Vectra Meriva

Description

Platinum Electrode : Platinum withstands exhaust temperatures and is both catalytic and conductive, to assist in the interchange between oxygen ions and oxygen molecules.
Dual Shield : The holes in these high temperature shields are offset to inhibit the access of water droplets to the heated ceramic surfaces , thus protecting the ceramic.
Plasma Sprayed Protective Coating : High temperature plasma sprayed ceramic coatings have microscopic pores that protect the electrode and control the diffusion of exhaust gas.
Stable at 1000 degrees C : The high temperature stability ensures long life at elevated exhaust temperatures.
Rolled Threads: Rolled threads do not have the sharp edges and burrs of cut threads. The rolled threads are easy to install and give a more consistent compression of the crush washer.
Stainless Steel Hex Nut : High temperature stainless steel resists corrosion and leaking.
Ceramic Element : The ceramic element is modified zirconium oxide, which transfers oxygen ions. This ion transfer is the basis for the operation of the oxygen sensor.
Crimped Weather Seal : The crimp helps maintain seal integrity despite the expansion of the metal shell caused by multiple wide temperature excursions , from freezing cold to glowing hot.
PTFE Filter : The filter repels water droplets while allowing air to pass. The filter ensures clean, neutral air in the air reference.

Please Note: this is direct fit, not universal type lambda sensor.
The Lambda sensor or oxygen sensor is located in the manifold or exhaust system. They analyse the amount of oxygen in the fuel beeing used by your car.
The Lambda sensor is a vital component of any modern car, as it makes modern fuel injection possible and helps to regulate the emission of harmful gases into the atmosphere.
This sensor then sends signals back to the ECU to calculate the engines fueling requirements.
It is worth checking that your Lambda sensor is working properly, as faulty ones can lead to the catalytic converter becoming damaged and result in.
