I doubt the code said to replace the O2 sensor. It probably said there was an issue with the data it was sending to the computer.
Sometimes the sensor is faulty, and sometimes there is a problem with the fuel system.
The O2 sensors give the computer data it uses to adjust fuel mixture.
If you can get the actual trouble code or codes we can advise.

SOURCE: check engine light on replaced

Hello and welcome to FixYa!
You may need to drive it for atleast another 20 miles to reset the system. If the problem still persists, I strongly suggest that you remove the positive battery connector and let it sit for atleast 5mins. before reconnecting it. This will reset the system and can get the check engine light.
Hope this helps and thank you for using FixYa! Have a good one!

A blown O2 fuse or a short or resistance in the wiring can set this code. A ECM/PCM internal fault can also be the problem.

Hyundai oxygen sensor

Why are you going back to a shop that can not
diagnose an O2 Sensor issue?
The only help you can get, is from someone properly
diagnosing the problem
Can't tell you anything, as I do not know what the codes
were, or were they the same every time
What was tested & how,that is the key.
Is that a V6 & what was short & long term fuel
trim on each bank?
Was the old & new sensor checked with an
oscilloscope? Why was it replaced?
Was the intake & exhaust smoke tested for
vacuum leaks?
Many questions & things to know & check,
obviously that shop can't solve the most common
& somewhat easy problems.

Hi, I have a 96 Jeep Cherokee with straight 6 cyclinder engine.The check engine lights on and Itook get to be put on a machine and the codes readed P0132,P0135,P0300,P0301,and P0420. Could you tell me

p132+ an O2 sensor reading is high bank1,sensor1, p135=O2 Heater circuit is bad, bank1,sensor1.

P300= Random misfires, p301 misfire cylinder1.p302 misfire cylinder2

p420 Bank1 Catalytic converter efficiency failing

What this means is that the Bank1 O2 sensor is either bad or the wiring to it is defective. Check for heat burnthrough on wires. The misfires started randomly and now pinpoint to cylinders 1 and 2.

The Catalytic converter failing because the misfires are clogging it. This can self correct once the cylinders stop misfiring.

Which messed up first is where you start solving this. Replace the O2 sensor, it is fouled out on Bank1. The heater circuit(p135) just makes it work faster and has little effect once you are underway. But high resistence in the O2(p132) means it is coated and ineffective.

There is a problem with firing #1 and #2 sparkplug. Probably the cause for the Catalytic converter plugging. A cracked coil, plug wires, sparkplugs are some causes as well as dirty fuel injectors on those 2 cylinders.

It is a cause and effect situation where 1 part fails and damages another. You need to fix the source of the problem or you will repeat th damage.

Can the fuel injector cleaner damages oxygen sensor?

I've always heard that too much injector cleaner may destroy seals or o-rings, but don't recall ever hearing it could damage sensors. Sounds like you need a new one.

Location 02 sensor Bank1 sensor2 on 2001

Bank1 refers to the driver's side of the engine, so follow the manifold from the engine back towards the catalytic converter, sensor1 will be before the cat and sensor2 will be after the catalytic converter.

Check engine light is on. Air Fuel Sensor1 (Bank

It sounds like you have an air leak in the air horn, check out the air filter compartment,make sure it is on there tight, no cracks, make sure there are no cracks in the air horn, the rubber to the throttle, make sure all the hoses are connected, and not making noises. One thing you can do is spry wd-40 on the intake manifold at the gasket line and make sure it doesn't leak there, if it levels out or changes idle it is leaking. A spray bottle of water will do the same thing. Check it out.

Check engine light on, 1997 cadillac Deville.PCM codes

PO135 is oxygen sensor Bank1 sensor1. PO404 is EGR.
personally, I'd pull EGR off, clean pintle good with throttle body cleaner or carb cleaner, re-install, erase codes & try it for a while & see if it code(s) come back.

04 kia sorento runs poorly

Might be going super simple here but from what you have said have you checked the wiring on your sensors? If you know that one works and you swap it and its not working its very possible the wires farther up are shorted or burned somewhere.
