What is an 02 / Sensor Lambda
An O2 sensor or lambda sensor also known as an oxygen sensor. It is one of the most important elements of petrol and diesel vehicles a very important aspect of vehicle emissions. The main purpose of the oxygen sensor is to monitor how much unburned oxygen deposits in the exhaust stream of the vehicle as the exhaust gas leaves the engine. It checks if the catalytic converter (CAT) works properly and the engine is running at optimum performance.
Oxygen sensors are connected to the vehicle’s ECU (electronic control unit). That way, if the oxygen levels are high or low, the lambda sensors signals the computer and the check engine light (engine management light) is displayed on the vehicles dashboard.
The amount and location of oxygen sensors vary from vehicle to vehicle, dependent on number of exhausts, power of vehicles, engine layout etc. The main aim to get two readings, one is upstream and the other is downstream, the upstream oxygen sensor is located on the exhaust pipe, while the downstream sensor is closer to the catalytic converter. The main idea is for the ECU to receive more detailed information and calibrate the engine for better fuel efficiency and performance.
02 Sensor / Lambda Removal
The reason for removal is faulty or degraded oxygen sensors as they become immersed with sulfur, lead, fuel additives, and oil ash causing failure. This component works under high temperature which damages the heater element, when oxygen sensors fail, they stop reading the exhaust gasses correctly. This can super-heat the converter far above normal operating conditions and lead to a meltdown of the catalytic converter. But the replacement of an oxygen sensor or converter is extremely expensive.
After a software delete the sensor will be removed from the ECU’s memory (programming) and it can also also be physically removed. Oxygen sensor removal / delete is an important tuning solution for vehicle engines. After 02 / lambda disable remapping vehicles improve fuel efficiency and fuel economy, increased engine power / performance and cleaner emissions. Check engine lights and fault codes become permanently deleted, no more limp mode.
