OBD-II Generic Error Code P0164: How to Fix It

Q: Can I drive with error code P0164?

Yes, you can usually drive short distances, but it may cause poor fuel economy and could lead to catalytic converter damage over time. It is best to fix it promptly.

Q: What does Bank 2 Sensor 3 mean?

Bank 2 refers to the bank of cylinders that does not contain cylinder #1. Sensor 3 is the downstream oxygen sensor after the catalytic converter (third sensor from the engine).

Q: Will a bad oxygen sensor cause a check engine light?

Yes, a faulty oxygen sensor will trigger the check engine light and store a trouble code like P0164.

Q: How much does it cost to fix P0164?

DIY cost is around $30-$80 for the sensor plus tools. Shop labor can add $100-$200, totaling $130-$280.

Q: Can a vacuum leak cause P0164?

Usually no. P0164 is related to high voltage from the O2 sensor, which is more likely due to sensor failure or exhaust leaks before the sensor.

Abstract

Error code P0164 indicates that the oxygen sensor on Bank 2, Sensor 3 (the downstream sensor after the catalytic converter) is reporting a voltage higher than expected. This often means the sensor is failing, the wiring is damaged, or there's an exhaust leak near the sensor. While the vehicle may still be drivable, it can cause poor fuel economy and increased emissions.
