which sensors will get the check engine light (cel) to turn on
I am having a hard time with my car. I put it on a scanner and nothing comes up no codes at all, but the (CEL) is on.
Everyday my car gives me a hard time to start. I changed the crankshaft (REF) sensor that was the problem before. That didnt do any thing 4 me.
Now what do I do ?

 

It could be a weak battery. Have it tested at AutoZone for free. A weak battery sometimes makes the light come one but no codes are spit out because nothing is actually wrong with the car but the battery. This might also explain why it doesn't want to start in the morning.

 

cool your car and my car r twins
your **** is hot

 

o by the way its not the battery its brand new

 

My friends CEL just went on for no reason and nothing was wrong with it, Autozone can reset it for you if that happens. I've heard its common with Maximas that have miles and years on them. No biggie ... if nothing is wrong, Autozone will reset the light for you for nothing.
