P0058

2017-10-10

Description:

  • The fault code P0058 indicates that there is an issue with the heater control circuit of the oxygen sensor in bank 2, sensor 2. This sensor is responsible for monitoring the level of oxygen in the exhaust gases and sending a signal to the engine control module (ECM) to adjust the air-fuel ratio. A fault in this circuit may cause the sensor to be unable to operate properly and can result in poor engine performance and increased emissions.

Possible Symptoms:

  • Illuminated check engine light

  • Poor engine performance

  • Increased emissions

  • Reduced fuel economy

Possible Causes:

  • Failed oxygen sensor

  • Faulty wiring or connections in the circuit

  • Corrosion or moisture in the sensor or connection

  • Failed engine control module (ECM)

  • Electrical short in the circuit

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

  • Clean any corrosion or moisture in the sensor or connection

  • Replace the engine control module (ECM) if necessary

  • Repair any electrical short in the circuit
