  • Unstable engine operation, especially at idle
  • Unstable acceleration, jerking when moving
  • Black smoke from the exhaust pipe (rich mixture) or signs of a lean mixture

Causes

  • Failure of oxygen sensor bank 1, sensor 1 (depletion of life)
  • Poor fuel-air mixture due to air leaks in the intake tract
  • Damage to the wiring or lambda probe connector
  • Sensor heating element failure
  • Sensor contamination with silicone, antifreeze or oil from exhaust gases

How to Fix

  1. Read codes and real-time data - look at the voltage of sensor 1 bank 1 with a warm engine
  2. Make sure that the sensor heater is working properly (resistance 2–20 Ohms)
  3. Check for air leaks in the intake tract (with a smoke generator or aerosol)
  4. Check fuel pressure and injector operation
  5. Inspect the sensor connector and wiring for damage.
  6. If the sensor does not switch or produces a constantly low signal, replace the lambda probe of bank 1, sensor 1
