P0136 — O2 Sensor Circuit Malfunction (Bank 1 Sensor 2)

Powertrain (motor/växellåda)

DTC P0136 indicates that the Oxygen (O2) Sensor Circuit Malfunction (Bank 1, Sensor 2) has been detected. This means the powertrain control module (PCM) is receiving an implausible or out-of-range voltage signal from the downstream oxygen sensor, which is located after the catalytic converter.

The purpose of this monitoring is to ensure the proper functioning of the downstream oxygen sensor (Bank 1, Sensor 2), which primarily monitors the efficiency of the catalytic converter and influences overall fuel trim adjustments.

Vanliga orsaker

  • Faulty Oxygen Sensor (Bank 1, Sensor 2): The sensor itself may have failed due to age, heat, or contamination, leading to inaccurate voltage readings.
  • Wiring/Connector Issues: Damaged, corroded, or disconnected wiring/connectors for the O2 sensor can disrupt the signal path to the PCM, causing an intermittent or constant malfunction.
  • Exhaust Leak near the O2 Sensor: An exhaust leak upstream or near the downstream O2 sensor can introduce ambient air into the exhaust stream, skewing the sensor's readings and making it appear faulty.
