SOURCE: 2005 hyundai sonata - no warranty

go to autozone buy a repair manual.its about.$24.00 dollars.it will show you show you how to do your own repair.you go buy the egr valve and tps sensor.now on the egr valve make sure the port in the intake where the egr valve is not stop up with carbon.if so becareful and easy cleaning out the carbon using a piece of clothes rack .clean up the debris.reason so because egr valve is not cheap.i seen them from $250.00 and up.you dont want to buy one if you dont need it.

The problem is in the tumbler(s) inside the assembly. Before you do anything, try penetrating oil to see if that works... otherwise, the entire assembly will need to be replaced.

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).
