'99 Voyager Fault Codes

1999 PLYMOUTH VOYAGER

Hi, I own a 1999 Plymouth Voyager 3.0 litre with 85,000 KM. I had my van checked at a garage for fault codes. The scanner came up with. Bank 1 sensor 2. The mechanic told me it was my post-convertor O2 sensor. I purchased one, disconnected the battery and replaced it myself. Afterwards, the van ran like a top. I drove 120 Kms on 10 litres of gas. One day has passed and now 'check engine soon' light is on again. I retrieved the fault codes via the three key flicks and now I have Codes 12, 17, and 43. I can understand code 12 (battery recently disconnected). Code 17 states. Engine running too cool. Code 43 states. Fault in ignition coil control circuit.

My question is can this be happening because of the recent O2 sensor replacement? Or is there something else I should be looking at? Please help!

Most likely not but possible unless they share the same circuit. But still no. Cuz u'll get the same O2 post cat code again. So answer is no. Not becuz u changed the O2 sensor.
2nd. Get on google or this site and find out what is OBD2 codes structure and protocol b4 u try to fix it urself. It take more tools, knowledge and training rather than just replacing a parts on those 3 codes. If u wanna know hypothetical why. Email me or call me.I don't mind. But if u wanna perform the repair and have no knowledge, training or equipments b4. It is impossible to turn some1 overnite to be a mechanic. Good luck!
