Code: P0133 - O2 Sensor Circuit Slow Response Bank 1 Sensor 1

there are about a dozen O2 sensor codes. Tell us which one you have

• P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
• P0171 System Too Lean (Bank 1)

Hi Michael, After fixing errors you need to reset your computer by disconnecting the battery for a minute or two, Also you'll need your radio code to reset your radio, I hope this helped...........CHEERS..

SAE J2012 Revised DEC2007 lists Diagnostic Test Code (DTC) P0133 as "O2 Sensor Circuit Slow Response Bank 1 Sensor 1"

This code basically means that the upstream oxygen sensor on bank one of your engine is not responding as quickly as it should to changes in oxygen leavels in the exhaust.

The usual causes of this is an oxygen sensor that is just plain worn out (if it has a lot of miles on it) or an oxygen sensor that is contaminated by engine oil or antifreeze leaks causing these fluids to be burned in the exhaust (like bad piston rings, defective PCV valve, blown head gasket, etc.).

In any case, the oxygen sensor needs to be replaced. However it should be noted that if it is caused by contamination like that described above, replacing it will only result in a new oxygen sensor doing the same thing if the cause of the contamination is not repaired.

P0804 is the highest OBD-II trouble code.

Here's your Oxygen sensor codes.

Note: "Bank 1" is the side of the engine with cylinder 1. "Bank 2" is the other side.

Testing the the O2 sensor an other vehicle testing procdures should be done before replacing parts . The rear o2 has nothing to do with this code .
P0133 Testing H02 Sensor

Correct. The one upstream, closest to the engine.

check the mass air flow sensor there maybe dirt on the filiment inside the sensor causing false readings. cleaning or replacing it may make the codes go away.

I just came from an Autozone, and then spoke with 2 Hyundai dealership service departments and they all three stated the P0113 code is the Intake Air Temperature sensor (IAT, also referred to as the Mass Air Pressure - MAP - sensor) on the engine, not an O2 sensor found in the exhaust system.

yes i would recommend replacing the o2 sensor, 9 times out of 10 it will correct the problem and they usually aren't too expensive for the saturn's

P0133 is an oxygen sensor "response too slow" code (meaning it's not getting up to temperature quickly enough, and the computer is assuming damage to its heating element). P0422 is a catalytic converter problem indication (cat is below peak efficiency). It's assuming you have a failure with the primary O2 sensor and that the cat is also bad. Change your O2 sensor first, have the codes cleared, and see if the cat code comes back or if the O2 sensor change fixes both issues.
