1995 Mercedes Engine Code P0141
- Error code P0141 refers to the second oxygen sensor, located beside the Mercedes' engine's No. 1 cylinder. When you see this error, it means the sensor is not correctly gauging the temperature of the exhaust surrounding it, or not addressing it properly.
- An error P0141 could be caused by a short in the wiring harness or the heating element, an issue with the oxygen sensor heater wiring, or problems with the heating element resistance.
- Because the internal wiring cannot be repaired in the oxygen sensor, in many cases the only repair option is to replace the sensor.
