01 / About Wideband Oxygen Sensor
About Wideband Oxygen Sensor
A replacement probe for compatible wideband systems, requiring a matching controller to drive the heater and pump cell. Before ordering, use the full Bosch or AEM part number to confirm LSU 4.2 or 4.9 type, connector keying and cable length.

Fitment & installation: Wideband Oxygen Sensor
Check the model, hardware revision and connector pins against the device’s wiring diagram.
Match the controller model and specified sensor part number before connecting power. Keep the sensor connector and calibration element intact; route away from exhaust heat and water traps.
05 / Questions about Wideband Oxygen Sensor
Questions about Wideband Oxygen Sensor
Can LSU 4.2 and 4.9 be interchanged?
Do not interchange them without explicit controller support and configuration. Their heater / pump-cell control and calibration requirements differ.
Can the sensor output go directly to an ECU 0–5 V input?
No. The compatible wideband controller operates the sensor and produces the analogue or CAN measurement used by the ECU.
Why can an LSU sensor give a misleading lean reading?
Air drawn in through exhaust leaks can produce a lean reading. Check the sensor boss, upstream exhaust sealing, installation position and sensor-type setting in the controller. Also check heater faults and condensation.
How do I identify the correct replacement wideband oxygen sensor?
Match the sensor and controller part numbers, LSU 4.2 or 4.9 family, connector keying, pinout and calibration requirements. A generic AEM or Bosch description does not identify the exact replacement.
