Was the 02 infront of the convertor replaced on the drivers side? That is what the code is for. These chryslers are good for the heater circuit burning out in the pcm (computer)

Can't solve that here What codes do you still have? Who did the O2 R&R,and was it okey for awhile? You may not have an O2 issue,even though you get the codes. A Misfire will set a lot of unrelated codes on some vehicles

I hope you understand that codes, do not tell you what is wrong or what to replace. They can be sensors out of range over a period of time and the PCM sets a code, so you can check things out.
Even a mechanical issue,could appear as sensor failure
Was the correct sensor replaced?
Do you have high Fuel Pressure,driving the O2?
What do tail pipe emissions tell you?( Exhaust Gas Readings)

    I'am going with your feelings on this

    But-something is turning some light on or it won't reset to the ready state.

Note: the catalytic converter is located at after a little bit of beginning in Exhaust pipe.

SOURCE: Check engine light came on

My book says ( GM ) P1133 - HO2S/O2S Insufficient Switching Sensor 1 Or Bank 1 Sensor 1
Be that as it may - to clear the codes in your computer - disconnect the battery for a couple of minutes and see if that clears the codes. Let me know. Thanks

SOURCE: i have a problem with the oxygen sensor the check

The check engine light can come on for over 150 things, from a sensor to a loose gas cap, you will need to have the codes scanned, the computer stores codes when it detects something not working correctly,there are many auto part stores that will scan it for free and give you a print out of the codes, if you can give me the codes i could help you find out why the engine light is on, good day.

Where is oxy.sensor

Usually in the exhaust pipe near the engine.
They don't usually cause a rough idle, and the check engine light should be on if you have a faulty sensor.

My Dodge Stratus (1998 4 cyl) check Engine light is on. The error code says oxygen sensors were bad. Both oxygen sensors have been replaced. After resetting the check Eng light. The oxygen sensor

the upper 02 sensor is for air fuel mix while the secondary 02 sensor is for the operation and status of the catalitic converter are you sure the catalitic converter is not plugged. Could be if you have had a loss of power

Check engine light came on

Generally this happens because these codes were reset at a dealership etc. These problems should have been corrected before the codes were reset (reputable dealer). A common reason that these codes come on is because of excess hydrocarbon emmissions with a misfire. If this was a temporary event, the light would reset. Since it continues, another likely reason is the oxygen sensor in the exhaust system has failed.

Service engine light comes on reset it it and takes a couple o days to come back on .truck doesnt overheat but comes up 128 error is it the thermostat or engine coolant sensor

It is possible that your oxygen sensor needs to be replaced.
have it checked out, thats the most common reason the engine light comes on.
P0128 error means thermostat stuck open, replace it.
then reset computer with scanner, lights and codes should go away.

My check engine light came on again it went out for awhile came back on 3 weeks latr my mechanic disconnected the oxygen sensor

Find a better mechanic. Unplugging the sensor fixes nothing. If the light is on, theres a reason. If it needs a new sensor, it needs one.

Check engine light came on and I have done all maintenance on the car. I opened and shut the gas cap but the light still stays on. What do you think the problems it. The car runs great and drives like a...

The most common reason for an engine light to come on is a bad oxygen sensor. There can be many reasons for the light to come on. Most auto stores will plug in an engine analyzer and read the engine codes for free. At that time, they can also turn off the light. The stores motivation for reading your codes is to sell you the parts to fix it. A bad oxygen sensor will allow the car to run normally , only your gas mileage may suffer. Anyway let the car tell you what is wrong with it.

P0159 is what the read out tells me. Just what do I need to do about this? I turned off the 'Check Engine Light' and it's still off after 2 days. But......!!!

What does that mean? This involves the rear oxygen sensor on the passenger side. 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.

Symptoms You will likely not notice any drivability problems, although there may be symptoms.
Causes A code P0159 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
Possible Solutions 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 rear passenger side 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
