Car Oxygen Sensor: The Crucial Component For Engine Performance
We must be very careful to deal with Oxygen sensors car, as it is the most crucial sensor in cars. A faulty car oxygen sensor can change the parameters of your Car ECU. It can destroy the car's system as it is the only sensor providing information to the Engine Control Unit. It works like a scanner to scan fuel consumption and pollution-related information for the car ECU, and the ECU depends on this sensor's right or wrong information. Therefore, a faulty car oxygen sensor/lambda sensor can affect the ECU delivering false messages. The ECU controls injectors and injectors-related components. The state of the Rich or Lean fuel mixture can affect the car engine's performance.
It is my experience that DPF-related faults begin because of bad injectors or Lambda Sensors. The Heat Sensor also plays a vital role in the DPF system, but Heat Sensor acts when the DPF Regeneration System requires the DPF Regeneration.
Modern cars are full of electronics, and traditional old-style garages cannot repair these new gadgety cars. These vehicles have ECU, and these ECUs need properly updated diagnostics to diagnose the faults and to fix the car's faults. To do so, it requires Eepromming, Programming, Embedded programming, Codding and Configurations; even now, it is impossible to bleed car brakes without a diagnostic or Auto Transmission Oil.
Two-step Lambda sensors in car

Bosch Automotive Electrics and Automotive Electronics Systems
Car manufacturers are using Two-Step Lambda Oxygen Sensors for petrol cars. They extend into the exhaust means between the engine manifold and pipe, sometimes between the exhaust manifold and catalytic converter. The Lambda sensor in the car can be heated; it can be installed away from the engine, and it is safe and will run for a long time. Two-step Lambda oxygen sensors compare the residual oxygen in the exhaust gas with the oxygen in the reference atmosphere (air inside the sensor), indicating a rich or lean air-fuel mixture of exhaust gas. The sudden change in the character of these sensors permits air-fuel control. Operating principle The two-step Lambda oxygen sensors operate by the rule of the galvanic oxygen-concentration cell with solid-state electrolyte. The ceramic element is conductive for oxygen ions at approximately 350 ° C (safe, reliable operation at 350 C or sometimes 500 C). It means that the oxygen in the exhaust gas measures the air-fuel ratio. The integrated heater ensures that the sensor functions at low exhaust gas temperatures. When the engine starts, the Lambda control switches off until the minimum operating temperature of about 350 ° C is available. During this period, the engine goes into open-loop control.
