  1. YF (2011-2014) Sonata/i45
    I have looked at diagrams of this vehicle and it gives me multiple locations for the O2 sensor. The diagram shows two places for the 02 sensor if the car is SULEV and two if it is ULEV. My emissions certificate under the car hood says my vehicle is a ULEV. But I am seeing what lookes like the O2...

    Does anyone have a diagram with the locations of the o2 sensors? I pulled code P2297 and wanted to replace it but am not sure which one it is. I have the 2.4L
  3. Sonata YF Turbo
    Hello everyone, Does anyone have an idea why the voltage on the bank 1 sensor 2 of a 2014 Hyundai Sonata 2.0T will be zero? I already replaced the oxygen sensor and fuses, and the wiring harness looks okay. I also discovered that the compressor is not receiving power by testing the connector...

I didn't have access to a live scan tool and that sensor is a pita to check with a volt meter so I checked the spark plugs first. The plugs in 1, 3, and 5 had some carbon deposits...
  6. SM (2001-2006) Santa Fe
    2003 Santa Fe, 2.4 4 cyl. I got a P0421 code recently, so I thought I'd take a look at the cat and the O2 sensors to see what was going on, if they could be cleaned, etc. This is what I found: Looks like the top substrate has completely melted. Downstream O2 sensor also looks heat...
