Question about 2004 Mitsubishi Outlander

Service Engine - Error Code indicates o2 sensor issue

I bought this vehicle (used) for my daughter and it didn't come with an owner's manual. I'd like to know if replacing the o2 sensor is a good diy candidate or if it's better left to the pros.

Go to the dealer and order an owner's manual. It usually takes a special socket and strong dextrous arms to replace an O2 sensor. Let the pro do it.

I need to know the code dtc44 for a 1990 Buick Century

GM OBD Trouble Code 44

Auto Systems and Repair

Oxygen Sensor Error (Lean Condition Indicated) The ECM receives a signal from the O2 sensor based on the amount of oxygen in the exhaust. If there is excess oxygen in the exhaust, it is in lean condition and the O2 sensor voltage will be low. The ECM uses this information to adjust the amount of fuel delivered to each cylinder.
Fault Code Description
  • 44 - Oxygen sensor error (lean condition indicated)
  • On V-type engines with two O2 sensors, code 44 would indicate the left bank sensor is lean
  • Lack of power
Common Problems
  • Faulty O2 sensor
  • Engine vacuum leak

2000 Pontiac sunfire 2.2 got code 1137. How do I fix. Car won't start. I changed o2 sensor.

The 1137 OBD2 code is typically an o2 sensor problem as you have indicated, first I would make sure your replacing the correct o2 sensor as there are two (upstream and downstream), although it is possible that a bad o2 sensor could keep your engines fuel injection system from delivering the fuel to your engine, in my experience having a bad sensor typically results in a check engine light and running with a less than optimum fuel air mixture, it does not typically keep your vehicle from starting. If your still getting the 1137 error code after replace the o2 sensor and checking its connecting wires I would start looking for a bigger issue.

I have a misfire in the 4th cylinder and need new o2 sensors and im getting the p1409 code

Need to know vehicle history ,current issues in datail
& who is working on it

If you going to take it to a repair shop

Check engine sign appeared on my 2001 avalon , code error p1155, please advise

Appears it is an Oxygen sensor error, they are located in the exhaust system, in the v6, that code indicates the second bank (but unsure which bank that is) Ideally you need to take the car in for service, or at least inspect the Oxygen sensors, the code indicates that teh heater element has failed.

My daughter bought a 2003 pt Cruiser 2 days ago and the engine light indicator came on this morning. What should we look for.

Stop at auto Zone or Advance Auto parts and ask them to use their scanner to identify the fault code. That will tell you what needs to be fixed. As a Guess I would say the O2 Sensor but that is just a guess.

2004 Dodge Stratus Sedan. engine light stays on,

Take the vehicle to any auto parts store that offers to read the fault codes with a scanner for free and find out what that code is. If it shows Upstream or Downstream O2 sensor replace the O2 Sensor. There is a catch, dodge had an issue in the 2000 - 2004. The ECM will show a fault code that indicates the Catalytic converter is faulty. This is actually a faulty Downstream O2 Sensor. If you get a Catalytic converter fault code replace the O2 sensor first if you still have the problem then replace the converter.

Error code: Code of P0420 catalyst efficiency below threshold What does this mean? have replaced o2 sensor on cat but code continues.

I assume your Vehicle is an Audi/ VW as this is a VW fault code. The o2 sensors measure the oxygen in the exhaust gases and compare it to the out side air, there by working out how efficiently the the fuel is been burnt. The engine control unit will use this and other information to adjust the fuel quantity being injected. The catalytic converter breaks down certain gases in the exhaust fumes to comply with emission regulations. Some vehicles have an upper o2 sensor [before the cat] and a lower [after the cat]. The readings of the o2 sensors is compared and should be within a certain range. If not a fault will be stored in the memory. The Catalytic converter itself may not be working correctly due to contamination or the baffle may be loose[ usually indicated by a rattle in the exhaust]. One or both o2 sensors could be contaminated with carbon and not giving accurate readings. Also check other silencers for blockages.

How do i replace an o2 sensor in a 2005 chevy Colorado. I have the yellow engine light on solid. I was told that this is an indication that sensor #1 has to be replaced.. I wondered how to replace it and...

If you did not get an o2 sensor code or you didn`t get the codes read then I would not be replacing anything.The light is on for a reason and in order to find out why you have to get the codes read.Auto Zone or most parts stores will do this for free.Save your self some money and before you buy and replace the o2 sensor make sure that is the problem.There are 2 o2 sensors on this vehicle.Hope this helps.Good luck.
