SOURCE: PO420 code for 2003 Elantra

Danny,

Catalytic Converter Failure is a common cause of a P0420 Code. 1.) I would give a few calls to some muffler shops and get a thorough exhaust inspection done. As a leaking/damaged Exhaust Manifold, Catalytic Converter, or exhaust pipe could be some of the culprits as well. If it were any of those other items your car would give you a different OBD Code. Item #2.) This is not common with a P0420 Code. With the P0420 code you should have no driveability issues. (not to say that you wouldnt in an extreme rarety) Item #3.) Again this would flag an entirely different code such as P0455 (Large Evap Emission Leak) Item#4.) Engine Oil would not even set a code. I hope this helps you out, and thank you for using FixYa!

Sincerely,

JC

YES!... with various system operating difference. Disconnecting the alarm does not disable it.. it only silences the alarm. You will still need the Keyless Entry System Remote to RESET the alarm to start the vehicle.

SOURCE: P0139 code for a 2003 hyundai elantra. What is this code?

P0139 HO2S Circuit Slow Response (Bank 1 / Sensor 2). This is the downstream sensor (after the catalytic converter). Odds are the sensor is going bad. Check connections/ connector to this sensor. If you don't find any problem/trouble with this connector, replace the O2 sensor.

SOURCE: need fil for error code P2626 Hyundai Elantra GLS

P2626 O2 Sensor Pumping Current Trim Circuit/Open (Bank 1 Sensor 1)

I'll sure this has to do with a faulty O2 sensor. This sensor is usually located around the header of your car, or down more on your exhaust.

Try disconnecting your battery for 30 mins, hook it back up, and start your car again. This will erase the error. See if it comes in again.

Hope this help (remember rated this post).

2003 Hyundai Elantra GLS. Check engine light, code PO133


Did you use a aftermarket O2 sensor or a genuine Hyundai one? If it's an aftermarket one it may be bad or not as good as the OEM one. See here for more details and other potential causes: P0133

My 2001 hyundai elantra (automatic) loss power while driving


The check engine light usually comes on when there is a faulty sensor. or circuit. Sounds like you may have a faulty throttle position sensor. It would be best to have engine codes read to pinpoint exact problem area. Many part stores do this for free.

NO. These models do not have warnings on the transmission failure. There is warnings only when the transmission encounters electrical component failure, overheating(some cars), low fluid. Usually the warning is the O/D flashing light, or a seperate transmission light. Hopefully this helps
