How do I fix code P0133?

What repairs can fix the P0133 code?

1. Usually a replacement of the oxygen sensor will fix the P0133 code.
2. 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 oxygen 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

1. Check and repair exhaust leaks.
2. Check wiring problems such as shorted or frayed wires.
3. Check both the frequency and amplitude of the O2 sensor.
4. Check for worsening or contaminated O2 sensor, replace if required.
5. Check for inlet air leaks.
6. Check the MAF (Mass Flow) sensor for the right operation.

Can I 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.

Where is bank 1 sensor 1 located?

On most in-line engines, the bank 1 sensor 1 will be located at the engine’s front side, near the cylinder head. On most front-wheel-drive models with V6 engines, this sensor will be on the backside against the firewall. Most rear-wheel-drive cars and pickups will have this sensor on the passenger side.

Is bank 1 sensor 2 upstream or downstream?

Bank 2 Sensor 1 means Upstream Left/Front; Bank 1 Sensor 2 means Downstream Right/Rear; Bank 2 Sensor 2 means Downstream Left/Front. Many buyers brought the wrong Oxygen Sensor because they donot pay attention to the plug and the length of the sensor.

What is the code for a bad 02 sensor?

Once the oxygen sensor stops performing as intended, the vehicle computer detects that and turns on the Check Engine light. This will usually have a diagnostic trouble code (DTC) of P0138. Typically, you’d take the vehicle into the shop, where they’d diagnose the issue and replace the oxygen sensor for you.

What are signs of a bad oxygen sensor?

Here are some of the most common signs that your oxygen sensor is bad.

• A Glowing Check Engine Light. The bright orange Check Engine light in your dashboard will usually glow if you have a bad oxygen sensor.
• Bad Gas Mileage.
• An Engine That Sounds Rough.
• An Emissions Test Failure.
• An Older Vehicle.
