P0130

What it means

This code means the computer isn't getting the expected signal from the oxygen sensor located before the catalytic converter on the engine's first bank of cylinders. This sensor measures the oxygen content in the exhaust to help the engine run efficiently.

Is it safe to drive?

While you can often drive with this code, prolonged driving can lead to reduced fuel economy, increased emissions, and potential damage to the catalytic converter over time.

Most likely causes

• Faulty O2 Sensor (Bank 1 Sensor 1)

  high

  The sensor itself may have failed due to age, contamination, or electrical issues, leading to an incorrect or no signal.

• Wiring/Connector Issues

  medium

  Damaged, corroded, or loose wires and connectors to the O2 sensor can interrupt the signal to the PCM.

• Exhaust Leaks

  low

  Leaks near the O2 sensor can allow unmetered air in, causing the sensor to read incorrectly.

• PCM Failure

  low

  Though rare, an internal fault in the Powertrain Control Module could prevent it from properly reading the O2 sensor.
