Can you drive with a P0133 code?

Like with most O2 sensor problems, you can most likely keep driving with a P0133 code, but you’ll want to get it fixed. You’ll be using more fuel and won’t have a chance of passing an emissions test if required in your area.

What can cause a P0133 code?

P0133 Causes

  • Faulty O2 sensor (most common)
  • Faulty/Frayed wiring to the O2 sensor.
  • Exhaust Leak.
  • Engine Vacuum Leak.
  • Dirty Mass Air Flow sensor.

What causes O2 sensor slow response?

The slow response of an O2 sensor may be due to a sensor that is just getting old and over time may get contaminated with time with carbon and other contaminants that deteriorate the sensor over time.

What does Post Catalyst fuel Trim system Too Lean Mean?

Code P2096 stands for “Post Catalyst Fuel Trim System Too Lean (Bank 1)”. The code indicates that your car’s primary computer, which is often referred to as the powertrain control module or PCM, perceives a lean fuel-to-air mixture downstream of the catalytic converter.

Can you clean the oxygen sensor?

There are no true oxygen sensor cleaners that are safe to put through your engine. While some people choose to remove them and use a wire brush or an aerosol cleaner to remove deposits, we do not recommend trying to clean O2 sensors.

What does O2 sensor delayed response mean?

It means that your vehicle’s powertrain control module (PCM) has detected a delayed response time from the upstream oxygen sensor on Bank 1. Usually, any issue with the upstream oxygen sensor’s function can cause a decrease in engine performance, but it typically just triggers a Check Engine light.

What causes O2 sensor code?

An engine misfire, leaky exhaust valve or a leak in the exhaust manifold gasket that allows air into the exhaust may also cause this type of code to be set. If an O2 sensor has failed, especially prematurely, the cause often is contamination. Like us, O2 sensors slow down as they age.
