How do I fix error P0133?
What repairs can fix the P0133 code?
- Usually a replacement of the oxygen sensor will fix the P0133 code.
- At times the sensor itself will not be causing the code P0133, so a technician must check for other faults such as vacuum leaks, a dirty mass air flow sensor, or leaks in the exhaust system.
What can cause a P0133 code?
Code P0133 Common Diagnosis Mistakes Often times, the O2 sensor’s wiring is frayed or the Mass Air Flow sensor is dirty, which can both trigger Code P0133 to occur. Exhaust and Engine Vacuum Leaks can also cause P0133 to be triggered.
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.
How do you fix a slow oxygen sensor?
How to Fix
- Check and repair exhaust leaks.
- Check wiring problems such as shorted or frayed wires.
- Check both the frequency and amplitude of the O2 sensor.
- Check for worsening or contaminated O2 sensor, replace if required.
- Check for inlet air leaks.
- Check the MAF (Mass Flow) sensor for the right operation.
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 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 side is bank 1 on a Ford?
The Ford F-150’s Bank 1 O2 sensor should be found on the right or passenger side of the truck under the vehicle, near the engine before the catalytic converter. Look 12 inches above the converter, near the firewall to access it.
