Oxygen O2 02 Upstream & Downstream Sensor
The oxygen sensor is used to regulate a number of circuits, including those for the catalytic converter, fuel supply, injector, electronic control unit, control sensor, exhaust gas, diagnostic sensor, and injector.
The car's exhaust manifold houses the oxygen sensor, which is used to detect exhaust byproducts (including oxygen!) and primarily track the vehicle's performance.
The degree of wear on the zirconium sensor can be decreased by a double insulation protective cover.
The sensor body was laser welded to seal off the opening for impurities.
The sensor can operate at its peak efficiency thanks to the internal ceramic insulation.
Electronic signals are shielded from moisture interference by sealed cables.
234-9036+234-4190 are the reference part numbers.

What are the symptoms of an oxygen sensor going bad?
Here are some of the most common signs that your oxygen sensor is bad.
- Check Engine Light comes on--The first line of defense is the Check Engine Light. The Check Engine Light will illuminate if you have a bad or failing oxygen sensor.
- Bad gas mileage and rotten egg smell--If the oxygen sensor is going bad, the fuel-delivery and fuel-combustion systems will be thrown off. This excess fuel in the engine can produce a sulfuric, rotten egg smell, and may even produce black smoke from the exhaust.
- Rough engine idle and misfires--Since the oxygen sensor output helps control engine timing, combustion intervals, and the air to fuel ratio, a bad sensor can disrupt these engine functions, causing a rough or irregular engine idle and other engine-related issues.
