Mine keeps saying the front O2 sensor. I have replaced the front one 4 times and just last week replaced the other one. The light has come on again. This is starting to get costly and frustrating!

What are codes P0133 & P1134, for a 2005 Buick Lacrosse 3.8L V6 with 94,000 miles.


i have replaced an O2 sensor and had similar failure after 1500 miles.
I removed it, chkd it, reinstalled it and it ran fine.
P0133 is related to slow response of O2 sensor. P1134 is mfg specific so google that for ur car.

Check for intake leaks, intake hose leaks, check mass air flow sensor.
02 sensors will keep setting off a lean code until the air problem is fixed.

Okay, I've replaced my oxygen sensor last week and


if you used a direct fit O2 it should not be giving you the code again unless the wires are touching near the plug, you got a defective sensor.
if you use a universal it may not read properly.

I took my 2000 pontiac montana to auto zone on saturday and they ran there little test on it cause the light was on it came up with both o2 sencers were bad but i have changed the back one twice last month...


When you had one go bad, it fixed the problem for a short while. Now both they say are bad. 02 sensors last a long time if the engine has regular maintenance. Most likely your catalytic converter is bad. This will cause, at first the rear 02 to show bad readings setting a code. And as the converter progresses to get worse, it will make both 02 sensors give bad readings, thus setting off the codes.

Just last week i got my oxygen sensor changed because i had my engine light came on and i was told that was the problem. once it was changed the engine light went out, but today friday it came back on...


If you change an O2 Sensor ,and that was the issue,
the light on most vehicles should go out

Your saying you paid to have your vehicle diagnosed
and repaired

My answer or guess, is that they did a poor job at it.

The only time any Malfunction Indicator Lamp (MIL)
or Check Lights come on, you most certainly have issues

What they are, has to be diagnosed, as the codes you get,
do not tell what is wrong or to replace anything

I do not believe that all repair shops know that as of now

You may have a new and different problem from last weeks

I've had my Jeep in the shop 3 times over the past


an o2 sensor would not make your vehicle do this the o2 sensor may sending an error code do to the fuel being to rich or to lean while it's passing by.this sounds more like a bad map sensor ot mass air flow sensor try pulling them out and cleaning them

O2 sensor problem


I have a 97 gmc sierra .This truck is the same as the chevy ok.Its a 350 5.7 liter 4x4 Z71.I took it to auto zone which was my first mistake.They put it the scanner and said bad O2 sensor.Ok so which one is it i said.They dont know.Well there four (4) O2 sensors in this truck i hope you know that.I had to replace all four of them before i had to take it to a real shop.It seems the fuel pump i replaced a week earlier with an auto zone fuel pump was bad.Ive changed my feul pump 4 times now and have 235000 miles on still running.You need to get your fuel pressure checked.It should be 65 psi to start it and 55 psi to run it.If the pressures are good it could be a different O2 sensor or maybe the mass air flow senor.My last option would be the fuel pressure regulator because it seems to be a waste of time and money.I would get that fuel pressue checked first.Good luck.
