Both front oxygen sensors can fail at the same time

If you replace the front or upstream sensors at 100,000
miles, if they haven't failed sooner, your doing preventative
maintenance,so add that to the list

After that they slow down & you don't have the proper control
over the fuel trim & your vehicle is not as sharp in response to
your gas pedal request

The chugging is something you need to look into

The O2 Sensors are not causing that,you got things
that need attention,spark plugs,air filter,clean maf sensor
& check out ignition issues,worn out exhaust converter
causing a partially blocked exhaust system

Sounds like the engine bearings (crankshaft) are worn. Try using a heavyer grade of oil, unless you want to rebuild the engine.

SOURCE: I have a 2002 chevy tahoe and I just had an oxygen

Sound like either the mechanic didn't plug the sensor in all the way or you got a bad sensor, bank 2 should be the passenger side, sensor 2 is the sensor after the catalytic converter.

Not the fuel filter

More like a vacuum leak

Check engine light comes on i hooked up my code reader under the steering wheel and it threw this code PO133 any idea's of what it is or how to fix


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

2002 chevy express van 5.7 v8 error code PO154 Bank 2 sensor 1 oxygen sensor


That is a low signal error from the right bank upstream oxygen sensor. In most cases, it is caused by a weak oxygen sensor. Before replacing the oxygen sensor, double check fuel pressure, volume and quality. A low signal from the oxygen sensor can also be caused by a lean fuel condition.

2002 MR2 fuel system too rich bank 1 and bank 2


Peter. The dealer did diagnose the problem. They said the car needed all 3 oxygen sensors replaced. They were replaced and the car is now returning codes p0172 and p0175 which are the only 2 codes coming up when the check engine light came on. My question is if the dealer sold me the incorrect oxygen sensors could this cause the computer to incorrectly set the p0172 and p0175 rich fuel mixture codes. There are no other codes coming up. My plan at this point is to check and clean the MAF, check my fuel pressure, and also the TPS but I did not want to waste my time if it could possibly be that the new oxygen sensors where the problem. Any help would be appreciated.

Sombody please exsplain level 3 to me? And still can I get any answers on a level 3 entry?


The oxygen sensor has no affect or control over ignition timing. Its singular purpose is for the computer to know if the engine is getting too much or too little gas and to correct or "trim" the time and duration of injector pulse.
I would go back and scan again for codes-more might have been set since it started running rough. Post the codes here and someone will try to help you. Fixing the code for the o2 sensor may fix everything, at least one can hope so. Good luck.

CODE P0101 AND CODE P0341 i have a 96 chevy blazr 2dr 4x4 4.3L. I RECENTLY HIT A LARGE BUMP AND THE TRUCK STALLED.PULLED OVER AND STARTED IT BACK UP .IT RAN A SECOND OR TWO THEN STALLED AGAIN. IT WASN


Well the code 101 is for the MAF sensor and code 341 is for the cam sensor if equipped.
I'm showing a distributor for that engine so its possible something is going on inside of it.
My first guess would be something in the engine harness that was jarred loose.
You might have to test the circuits at the ECM to see if anything is not making the circuit back to it.
If the engine won't idle and the MAF code is present, you could have a large vac leak somewhere.

2001 Nissan Sentra. Car starts with no power, but after a few restarts, gain power again. Code is PO420.


Hi, P0420 code means a catalytic converter fault.
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream O2 sensor reading should be fairly steady. Typically the P0420 code triggers the Check Engine Light if the readings of the two sensors are similar. This is indicative of (among other things) a converter that is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.
  • Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
  • Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
  • Inspect the downstream heated oxygen sensor (HO2), replace if necessary
  • Replace the catalytic converter

What does the oxygen sensors look like in a 2003 Chevy Venture (warner Brothers Edition) ? How many are there? Where are they located? Can you show a picture of them in place? How do i replace them? Chevy...


There should be an O2 sensor before and after the catalytic converter on your vehicle, so it will have 2 sensors. You'll need a 7/8" open end wrench or an O2 sensor socket to replace them.

It'll look something like this: http://www.carsteering.com/data/all_images/48-01718.jpg
