Question about 2006 Hyundai Elantra

1 Answer

2004 Hyundai Elantra

While driving the car shut off. I ran a diagnostic at auto zones and it ran the codes P2626, P2231, P0010, P2251, and P0030. I have googled them and am not coming up with anything aside from it all leading back to the O2 Sensor. It has 110,000 miles. Any help would be greatly appreciated. I know nothing about cars. Thanks.

First of all. clear the codes in the fault memory then drive it again. and check for new codes. if it is o2 sensor again then it could be many things other than the sensor. what you have to understand is that the car is making the decision of what it thinks is wrong. and the final thing in the whole process is the exhaust gas. if its wrong then the sensor will pick it up. it might well be the sensors at the current mileage, but dont rule out the obvious. air leaks on the intake system (EGR). etc. miss fires. the list goes on... hope this helps..

P0010 code

P0010 on a Hyundai means your camshaft positioning oil control valve solenoid is screwed up. Could be the wiring to that, as well. Check the wiring first, if any loose connectors, clean and reseat and see if code stays cleared. If not, the solenoid needs replacing. The VVT (variable valve timing) system on this engine has been troublesome, and Hyundais in general are troublesome. People only buy them because they're cheap and disposable. There are cases where a P0010 is indicated a faulty ECM...big bucks.

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).

My check engine light came on it said P2626

This is an O2 sensor failure with the sensor located in the manifold. The associated heater probably failed causing the sensor to fail.
