LCU ONE Replacement Lambda Sensor only for LCU One. This is the Lambda sensor only and requires the LCU One control unit. If you don't have the Control unit you will need to purchase the LCU One Kit which includes the Lambda sensor and the Control Unit.
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 be- ing 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.
