P1105

NOTE:
- The heating for oxygen sensors behind the Three Way Catalytic Converters (TWC) is not switched on immediately at engine start, but when the calculated exhaust gas temperature drops below 308°C (586°F) (Read measuring value block, display group 42, channel 1)
- The diagnostic trouble code "P1105/17513" is set as soon as the Oxygen Sensor (O2S) heater is switched on (the vehicle must be driven approx. 60 sec. under load) and the heating current is greater than 10 A for longer than 80 ms.
