Key Reasons for replacing lambda sensors

Lorem ipsum dolor

The lambda sensor is a key component of a vehicle’s engine management system and also prevents damage to the catalytic converter. Only if the sensor is working perfectly will the engine be able to operate at its full efficiency and keep exhaust emmissions below strict limits.

An OE quality lambda sensor is essential to deliver optimum fuel economy and emissions performance.

The Lambda sensor measures the oxygen content in the exhaust gases and converts this into an electrical signal for the engine management ECU. The ECU will then adapt the air/fuel mixture accordingly to ensure optimal engine performance and reduce the vehicle’s emissions.

Disadvantages of an old sensor

  • It will not measure the level of oxygen in the exhaust gases correctly
  • Increased fuel consumption
  • Poor engine performance
  • Poor exhuast emissions
  • Damage to catalytic converter

Advantages of a new sensor

  • Fuel savings of up to 15 %
  • Increased engine power
  • Better for the environment
  • Longer operating life of catalytic converter

Used Bosch Lambda Sensors?

Don’t worry, they’re not used! Part of the quality process during production is for each and every Bosch Lambda Sensor to be tested at full operating temperature before it leaves the factory. That is why each one has the heat tarnish on the unit.

Air-mass meters

Original Quality that Pays Off: Bosch Air-Mass Meters

In order to ensure that legal specifications for emissions are complied with and that the vehicle is not consuming fuel unnecessarily, air and fuel must be fed through the engine in a precisely defined ratio. This takes place by means of an air-mass meter or air flow sensor which detects the actual air-mass flow and transmits the measured values to the regulating and control systems of the engine.

When, as a result of the energy crisis, the reduction of fuel consumption became an important development goal in 1972-73, Bosch introduced air-volume measurement with the mechanical K-Jetronic gasoline injection and the electronically controlled L-Jetronic gasoline injection. As the inventor, Bosch is still a pioneer in the field of technical development for air-volume and air-mass metering.

Bosch Hot-Film Air-Mass Meters

Bosch hot-film air-mass meters are equipped with the latest technology (e.g. with integrated temperature, humidity, or pressure sensors) and microelectronics. In newer versions they are extremely reliable as they are highly resistant to contamination. Bosch hot-film air-mass meters work with utmost precision and thus make a significant contribution to minimizing the vehicle’s fuel consumption and emissions.

Replacing the Air-Mass Meter

If the air-mass meter on a vehicle needs replacing, it pays off to rely on first-class Bosch quality. This is because Bosch air-mass meters are perfectly adapted to the vehicle and guarantee optimum performance for minimum consumption.
