Hello Scotty. I have shevy sonic 2012, DIC system shows errors in intake, exhaust camshaft sensor, and fuel trim system lean. I changed these sensors, flushed the engine, replaced oil and added nap ceramic. We rested the car DIC
After driving for 2 miles, check engine reappears. I cleaned O2 sensor. Could it be faulty fuel pump?
Well, if you keep getting the codes for those sensors after you change them, that usually means that the timing chain or timing belt has stretched and needs replacing because it's now the wrong length. So the sensors give bad data even though there's nothing wrong with the sensors
Next time please put your question in the body of your post instead of the title, which is intended for a short description of your topic. Thank you. (Title edited.)
