Link Wideband 02 Sensor (LSU49) Bosch

This 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 1 measurement as well as for 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.

This sensor can be used with all wideband controllers and ECU’s that support LSU 4.9 sensors. This includes:

Link G4+/G4X Fury and G4+Thunder ECU’s – These have onboard LSU4.9 wide-band control.
Link CAN-Lambda Controller – These are sold new with a sensor, so this sensor by itself is only required if you need a replacement.
