2017-10-10

Description:

  • The fault code P0052 indicates that the HO2S (Heated Oxygen Sensor) control circuit for Bank 2 Sensor 1 is experiencing high voltage, which may cause the engine to run poorly or result in decreased fuel efficiency.

Possible Symptoms:

  • Reduced fuel efficiency

  • Illuminated check engine light

  • Rough idle or stalling

  • Engine hesitation or misfire

Possible Causes:

  • Damaged or faulty HO2S sensor

  • Wiring issues in the sensor's control circuit

  • Damaged or corroded connections in the control circuit

  • Malfunctioning powertrain control module (PCM)

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 HO2S sensor

  • Inspect and repair any damaged wiring or connections in the control circuit

  • Clean and tighten any corroded connections

  • Replace the powertrain control module (PCM) if necessary
