I have a 2013 sonic with a1.8 liter.I started getting a lot of codes. As they popped up, I took care of them. I'm exausted and broke! I have replaced so many things,but think I'm getting close to getting it running well. I've replaced the knock sensor, crank position sensor,pcv valve, (which is built into the valve cover),imagine coming up with that one? Anyway, found out that I had a leaky radiator,changed it out,then a P00B4 code popped up.(this is the radiator temp sensor). replaced it and ran fine for a week. now the same code came up and guy at parts store told me that its showing high voltage to that sensor. any ideas on how I can fix this,or,what I should look for?
