41 Oxygen Sensor Heater Monitor Bank 1 - Sensor 1
    85 linear Sensor temperature 
Monitors the electrical heater output of the sensor. The electrical output is controlled by means of an output-stage depending on the sensor ceramic temperature. When the control variable exceed's maximum value and falls below the sensor minimum temperature, a sensor with a defective heating is detected.
Standard range of the ceramic temperature [°C] : 760 - 800°C		 lower/upper threshold 96 0,1°C per bit °C P0135
42 Oxygen Sensor Heater Monitor Bank 1 - Sensor 2
    81 binary Sensor resistance 
Checking the Nernst element internal resistance of sensor 2. When this is too large the sensor cannot be heated sufficiently, and an error is detected.		 upper threshold 01 1 per bit Ohm P0141
45 Oxygen Sensor Heater Monitor Bank 2 - Sensor 1
    85 linear Sensor temperature 
Monitors the electrical heater output of the sensor. The electrical output is controlled by means of an output-stage depending on the sensor ceramic temperature.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
