What is an oxygen sensor?
Oxygen Sensors are also known as O2 Sensors. Oxygen Oxygen sensors ensors are part of the exhaust and emissions system. They measure the ratio of air to fuel of an engine which determines whether the engine is running rich or lean. The information is read by the engine control unit (ECU) to control and optimise the amount of fuel or oxygen. Modern vehicles often come with a number of oxygen sensors and are positioned in the pre-cat sensor position and/or post cat sensor position. Further, vehicles may have a left and right pre-cat sensor arrangement and a left and right post cat sensor arrangement. The oxygen sensors in these positions are sometimes the same as each other or may differ. The oxygen sensor is usually made up of the probe at one end and the plug on the other end. Plugs are usually specific to the application whereas the probes may differ in shape and size depending on the brand of the oxygen sensor. In these cases the thread of the probe must still be exactly the same as the original in order to fit.
How do I know if my oxygen sensor is faulty?
Oxygen sensors are serviceable items and have a limited life span. Oxygen sensors may develop soot, oil or other deposits on the probe. When the oxygen sensor begins to fail, decreases in fuel economy and/or increases in emissions are noticeable. Other symptoms include rough idling, stalling and delay in acceleration. Most cars will also ensure the driver becomes aware with a dash light indicating the malfunction.
