  Check engine light on. Scanned for codes, O2 sensor bank not within threshold. Changed O2 Sensor. Most catalytic Converters today are not quite right, therefore we need a alternative. For Approximately $45.00 O2 Sensor CEL Eliminator which is a mini catalytic convertor to reduce computer reading, attach to Cat screw in actual O2 sensor into it, clear codes and done. It Works.

  The engine light of my 2014 Aveo has been driving me crazy. I have changed the camcord sensor , changed transmission oil and filter, serviced the car, changed the tensioner and timing belt, got the upper part of the engine checked for problems, the lifters and everything else are working fine. Yet still, that annoying light keeps coming back.Now I am thinking of selling my car, because I am afraid that something is going wrong everyday and no one seem to know what the problem is. Sometimes the brake just disappear for a few second, scaring me to death also. My car is a new car, i wonder if i am the only one who have these problems? Anyone with advice.

  2015 Prius C with 30,000 miles car won't start. The engine light comes on first so I'm assuming that's the problem but if I keep turning the ignition key, 4-5 other lights, including the battery light come on. Any idea what this could all mean?
