Bosch LSU 4.9 wide band Lambda sensor for extended and precise engine richness measurement.
This Lambda sensor is used by the DigiLSU Lambda controller (see our Lambda-meters) and can fit with gasoline engines and diesel engines as well.
Connector VW (ref : 1J0 973 713)

Note: This sensor cannot be connected directly to the Sybele ECUs. The DigiLSU or the LSU49-5V Lambda controllers must be interfaced between the ECU and this Lambda sensor.
