Check Engine Light (CEL) came on while driving. I said to myself, not another O2 sensor. Anyway, had to fill up with gas, lo and behold the gas cap was gone. If it was me, since I fill up full every 2 weeks, it took 2 weeks for the CEL to come on. Hence 4 questions,
Is the CEL caused by the removed gas cap?
If the gas cap was stolen, how long before the CEL to come up?
Bought a OEM gas cap for C$7 instead of C$24 from the dealer. Is that a good idea?
How long before the CEL turns off?
Thanks
