2017-10-10

Description:

  • The fault code P0050 indicates that there is an issue with the heater control circuit for the oxygen sensor in bank 2, sensor 1. The oxygen sensor is responsible for monitoring the oxygen level in the exhaust and helps the engine control module (ECM) to adjust the fuel injection and ignition timing. The heater is used to bring the oxygen sensor up to operating temperature more quickly for accurate readings.

Possible Symptoms:

  • Illuminated check engine light

  • Reduced fuel efficiency

  • Reduced engine power or acceleration

  • Rough idle or stalling

Possible Causes:

  • Failed oxygen sensor heater

  • Corroded or damaged wiring or connections in the circuit

  • Failed engine control module (ECM)

Related Parts:

  • Heated Oxygen Sensor: This is one of the parts that fails very commonly. It measures the amount of oxygen to ensure proper combustion. Problems in the Oxygen Sensor lead to poor fuel economy

Possible Solutions:

  • Replace the oxygen sensor

  • Check and repair any damaged wiring or connections

  • Test and replace the engine control module (ECM) if necessary
