There may be a loose or dirty connection at the sensor terminal , clean or tighten if ok trace the cable back to any join pull apart and clean . You may have to clear the fault from memory by removing battery cables for a few minutes . Make sure you have the code to reset the wireless ect.

This is where at home diagnosis and in-shop diagnosis diverge. A shop will begin by checking that bank for an over rich or lean condition, then moving closer to finding the problem which for example could be an injector with a bad spray pattern or leak, or a minor vacuum leak somewhere .(too many other items to mention) You can do further testing with the use of a manual and a decent digital volt-ohm meter.It takes more time and isn't always as productive but most times with a bit of research and learning on your part the problem can be found. Unless I made a lucky guess, I could spend all day writing down ideas and would not be correct.

Oxygen Sensor Connector locations

  1. Disconnect the oxygen sensor connector.
  2. Using an ohmmeter, measure the resistance between the terminals +B and HT. Resistance specification: 11 - 16 ohms at 20°C (68°F).
  3. If the resistance is not as specified, replace the sensor.
  4. Reconnect the oxygen sensor connector.

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

SOURCE: i have a 2003 hyndai elentra an i had both 02

Try first to clean out the MAF sensors and the intake with tuner cleaner spray. Check also the the fuel regulator. Check also for holes and gapes from the air filter to the intake manifold. An error on the O2 sensor mean does not mean it is faulty. It may also be related to the air fuel mixture. Check also the wiring of the sensors (MAF and O2).

There is more to codes & vehicle systems, than replacing parts

Any part that is replaced, has to fail a test, to need replacing & the
repair has to be verified & the systems wiring tested as well ,if the
component test of a part doesn't yield results

A Generic Code Reader alone, won't be enough to work on
any vehicle

2001 hyundai elentra check engine light stays on what would cause this when car runs great?


Easy, find someone that has an OBD2 meter and get the error code # ( an example is Po256) Then plug the code number into google and it will tell you what is wrong.
You have to have a sensor on the engine component for the ck engine lite to come on. Leaking fluid will usually not have a sensor, so this is not the engine light problem.

How to reset 2004 hyundai elentra engine light


you would need to have it reset by a scan tool that most garages have,there are some cheap units available to the DIY mechanic.But importantly you need the fault codes read that have caused it to light up.There may be an issue with your vehicle that should be repaired.If there are codes up when read,ask to have them reset anyway.Any that wont will need attention.Supply the codes to me and I will be able to give you information on the faults and repair if needed
.I hope this helps you.

My engine light came on. error codes show P2195 and P1166


The fuel pump is vapor locking, common problem in high temp/altitude states. Call the dealer and see if campaign t-13 applies to your car, if the car was originally sold in a low altitude state, it won't apply. I recommend the fuel pump be replaced with updated fuel pump sub assy.
