Code P0133 Hyundai Description
The P0133 Hyundai code indicates that there is a slow response from the oxygen sensor located in Bank 1 Sensor 1 of the vehicle. This sensor plays a crucial role in monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module for optimal fuel mixture adjustments. A slow response from this sensor can lead to incorrect fuel-to-air ratios, which can result in poor fuel economy, increased emissions, and potentially damage to the engine over time.
Common Causes of P0133 Hyundai
- Faulty oxygen sensor
- Wiring or connector issues
- Exhaust leaks
- Vacuum leaks
- Engine running rich or lean
Symptoms of P0133 Hyundai
- Decreased fuel efficiency
- Rough idling or stalling
- Engine misfires
- Check Engine Light illuminated
- Increased emissions
How to Fix P0133 Hyundai
- Diagnose the issue by using a scan tool to monitor the oxygen sensor's response time.
- Inspect the wiring and connectors for any damage or corrosion.
- Check for exhaust leaks and repair as necessary.
- Test the oxygen sensor's functionality and replace if it is found to be faulty.
- Clear the error code and perform a test drive to ensure the issue has been resolved.
Cost to Fix P0133 Hyundai

it didn't pass inspection today,but my Hyundai is working(running fine so far.just tell me what to do first with the code po 133 o2sensor circuit slow response bank1 sensor1,on emission certificate sir;
-
You have to replace the Oxygen (O2) Sensor to fix the problem, then clear the code and drive your vehicle for a couple of days.
-
how do I clear the code after installed an new sensor!?.where do I look when it comes to the wiring if is to poor like in my case; 02 sensor,bank1 sensor1;thanx's

car shut off,at red light. restarted, first try. After about 30 ft car lurched. Check engine light came on. Code reads po133. Driving home car shut off while driving, restarted shut off again. Restarted 5th time tuned key. Was on incline. No battery weakness. Both shut off occurred after about 3 min warmup. Had upstream, down steam 02 sensors , along with cat converter, to clear po421 code.2002 Hyundai sonata

A faulty O2 sensor will not cause the engine to stall. Since you have the P0421 code and the engine is stalling, then you may have a clogged catalytic converter. Any other symptoms, like rattle from exhaust system?
-
Catalytic converters was replaced, cleared up P0421 code. Car now stalling , lurching, shut off while driving. Code p0133.

how do you clear the code after installed a new up stream 02 sensor,i just put a new one and light still on,do I need to disconnect the battery {positive]off!?I understand that the down-stream is the same like d-up stream 01sensor!?
. -
The P0335 which is for Crankshaft Position Sensor will cause the engine to stall and lurched. Replacing the sensor should take care of the problem.
-
Get a cheap code reader from Harbor Freight or most auto parts stores. It will have an erase codes function. The downside is that is resets ECM "monitors" that will require several driving cycles to reset before you can pass inspection, even though the check engine light is off.
A $40 reader will tell you the code numbers and supply a booklet to see what they are. An $80 one will let you read sensor voltages and you can see them increasing or decreasing
-
I got my car diagnosed and the code p0133 popped up and said it was the bank 1 sensor 1. So I got it replaced and the engine light came on again. What else can be the problem if that's all it's reading when doing the diagnosis? Hyundai Tucson 2006

The next step is to check for exhaust leaks, either on the exhaust pipe or manifold gasket. If no leaks are found, then you could try reprogramming the Engine Control Module.
