Bosch LSU 4.9 Probe
The Bosch LSU 4.9 Probe sensor is designed to measure the proportion of oxygen in exhaust gases of automotive engines (gasoline or Diesel).
The wideband lambda sensor LSU 4.9 is a planar ZrO2 dual cell limiting current sensor with an integrated heater. Its monotonic output signal in the range of lambda 0.65 to air makes the LSU 4.9 capable of being used as a universal sensor for lambda one measurement and other lambda ranges. The connector module contains a trimming resistor, which defines the characteristic of the sensor.
The main benefit of the LSU 4.9 is the robust design combined with the high Bosch production quality standard.
Installation
This lambda sensor operates only in combination with a special LSU-IC, used in most Bosch Motorsport ECUs and lambda control units like LT4. You’ll find this unit and more on our homepage at Accessories/Expansion Modules.
You should install the lambda sensor at the point, which permits a representative exhaust-gas mixture measurement, which does not exceed the maximum permissible temperature.
Install at a point where the gas is as hot as possible.
Observe the maximum permissible temperature.
As far as possible, install the sensor vertically (wire upwards).
The sensor is not to be fitted near the exhaust pipe outlet so that the influence of the outside air can be ruled out.
The exhaust-gas passage opposite the sensor must be free of leaks to avoid the effects of leak-air.
Protect the sensor against condensation water.
The sensor is not to be painted, nor is wax to be applied or any other forms of treatment. Use only the recommended grease for lubricating the thread.
