2011 Hyundai Sonata--I changed my battery on Saturday morning and the ck engine light came on. I followed the instructions in the forum and disc the cables for 1/2 hour then connected the negative cable first then the positive. Light went out than came back on. Went to Autozone and had them run a scan that showed P0106 MAP sensor fault so I replaced the sensor with a brand new one $81.00 and the light was still on. Again I disc the cables and the ck engine light turned off but again turned on. Drove close to 75 miles and still on. I went back to Autozone this morning and when they attached the code reader the light turned off. I drove less than 1/4 mile and it is on again. PLEASE HELP! 2 Answers
