What is the function and location of the oxygen sensor in the Honda CRX?

There is an oxygen sensor in the exhaust manifold, which controls the air/fuel mixture by measuring how much oxygen is in the exhaust gas. It sends signals to ECU and helps it to change fuel injection duration. It consists of a zirconia-made sensor shaft with a platinum-coated inner surface forming a single electrode. Additionally, some 1990 cars have heating sensors that speed up starting after cold engine and maintain stable outputs during warmup period.

About Honda CRX Oxygen Sensor

The role of Honda oxygen sensor is to effectively control fuel emissions for better engine performance and fuel economy. It analyzes the exhaust fumes and deposits produced by the engine to gather data of the air-fuel ratio. If the ratio is off, the sensor sends feedback to the vehicle's engine control system so the fuel mixture can be adjusted accordingly. Common signs of a faulty oxygen sensor are unstable idling speeds and a sudden drop in gas mileage. Heated sensors need to be replaced after 100,00 miles; 50,000 miles for unheated.
