Check under the carpeting on the driver's floor. There should be a compartment that houses the PCM.

PO-139 I had that sensor change 3 weeks ago and the check engine light came on again this morning.Thanks


Probably replaced a good sensor. This codes could be from a bad sensor, a vacuum leak, or an exhaust leak before the sensor.

Either go to a local garage that services Fords and ask them to look up the code in their diagnostic machine manual, or buy yourself a plug in diagnostic code reader available at automotive supply stores (plugs into the multiconnection under the dashboard, the same place where they attach the diagnostic machine during inspection).

2004 hyundai elantra oxygen sensor


Your Elantra has more than one oxygen sensor. There is a pre-catalyst sensor and a post-catalyst sensor. Both can be found on the exhaust. You simply disconnect the sensor wire and remove the sensor plug with the proper size deep socket. Be sure you have the correct sensor for replacement.

Because of the heat involved with the exhaust, make sure the engine is cool before attempting to remove and replace the sensors. They may be tough to remove so a shot of WD-40 or 5-56 spray may need to soak into the threads to ease removal. When you replace the new sensors, a coating of anti-seize will be helpful for future removal.

Keep in mind that one malfunctioning sensor can send information that will set off codes on other sensors "downstream" or send codes from other emission controls on the engine.

I have a 2001 Hyundai Elantra. The engine light


Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.Go to www.hmaservice.com and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.

Air bag light stays on


If your airbag light comes on it means its not working. Some of the newer airbag systems have weight sensors under the seats and anything lodged under them can disable the passenger airbag and possibly cause the light to go on. If there are no other symptoms, and nothing impeding the airbags then the car thinks the airbag wont work. If you are concerned for your son's safety, take it to a qualified mechanic and have them check/replace your airbag. Good Luck!

Will a bad oxygen sensor cause my car not to start?


An o2 sensor won't cause a no start issue. I'm praying your anti-freeze mixture was correct that day though.

Service Engine soon light Code P0133


I just came from an Autozone, and then spoke with 2 Hyundai dealership service departments and they all three stated the P0113 code is the Intake Air Temperature sensor (IAT, also referred to as the Mass Air Pressure - MAP - sensor) on the engine, not an O2 sensor found in the exhaust system.
