How do I fix code 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 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 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 does po133 mean?
The code P0133 indicates your vehicle’s oxygen sensor is having a problem. The oxygen sensor essentially works by transmitting a voltage reading to the computer. This reading changes every time the air-fuel ratio changes, which in turn changes every time the driver presses the pedal.
What side is Bank 1 on a Chevy?
Bank 1 is on the side with cylinder 1. Bank 2 is the side with cylinder 2. Most commonly Bank 1 is towards the front of the car if it has a transverse engine. The easiest way to discover the right cylinder bank is to check your car’s repair manual.
What causes high O2 sensor voltage?
The high voltage condition from the O2 sensor is indicating a lack of oxygen in the exhaust or other related problems, such as a leaking fuel injector or a broken up catalyst inside.
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 is slow circuit response?
Diagnostic trouble code (DTC) P0139 stands for “O2 Sensor Circuit Slow Response (Bank 1, sensor 2).” It indicates that the powertrain control module (PCM) has detected a potential issue with the signal from the rear oxygen sensor on bank 1. But the rear sensor’s signal should vary somewhat over time.
What is a po430?
Code P0430 indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by the vehicle.
