Lambda sensors are exposed to extreme heat, soot, and chemical contaminants. Failure is often caused by:
Age-related wear — most sensors degrade over 60,000 to 100,000 miles
Contamination from oil, coolant, or fuel additives
Wiring damage or water ingress in connectors
Sensor tip damage during exhaust or engine work
Exhaust leaks upstream of the sensor, skewing readings
Poor fuel economy due to rich or lean running
Rough idle or hesitation during acceleration
Check Engine Light (MIL) illuminated — often with codes like P0130–P0175
Failed emissions tests (MOT)
Increased exhaust emissions, including CO, HC, and NOx
Delayed or failed DPF regeneration in diesel applications
Always verify sensor position (upstream/downstream, bank 1/bank 2) before fitting
Apply anti-seize compound to threads, but avoid contaminating the tip
Check the connector and wiring for heat damage before installation
Tighten to manufacturer torque spec to avoid sensor or thread damage
Clear all fault codes and monitor live data for switching function and response time
Knock Sensors
Detect engine knock to adjust ignition timing and prevent damage
Idle Air Control Valves (IACV)
Regulate airflow at idle for smooth, stable engine performance
Exhaust Gas Recirculation (EGR) Valves
Recirculate exhaust gases to reduce emissions and improve combustion efficiency with VXPRO
