Thank you I'm delete the codes see if they come up again and if they do I'm going to replace the o2 sensor.P0133 OBD-II Trouble Code
Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)
What does that mean?
This is considered a generic powertrain DTC (code). That means it's definition is the same for all makes and models of OBD-II vehicles, however specific repair steps may vary depending on the vehicle. This trouble code involves the front oxygen sensor on Bank 1.
This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.
You will likely not notice any drivability problems, although there may be symptoms.
A code P0133 may mean that one or more of the following has happened:
- The oxygen sensor is faulty
- The wiring to the sensor is broken / frayed
- There is an exhaust leak
The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
- Check and fix any exhaust leaks
- Check for wiring problems (shorted, frayed wires)
- Check the frequency and amplitude of the oxygen sensor (advanced)
- Check for a deteriorating / contaminated oxygen sensor, replace if necessary
- Check for inlet air leaks
- Check the MAF sensor for proper operation
Oh ok thanks hopefully that's the problem nothing major because I just got the car and I'm already having minor problemsI think there are 2 on each side, one before and one after the catalytic converter. I can check my stock cats tomorrow to confirm. Keep in mind that mine is an SRT. Not sure of the difference in the SE.
