I took my 03 Vibe on tour last weekend so I decided to give the old girl a tune up. New shoes, brakes, iridium plugs/wires, air filter.
She loved it. I even spent time putting in new speakers and doing some sound deadening, made the trip much better. All our gear was in a trailer and 3 of us had plenty of room, it's nice being in a 3 piece punk band.
Anyway, drove 800 miles in two days, several states worth of driving, everything ran great, got a solid 28mpg even with the trailer. The last day coming home my check engine came on during an interstate drive. No noticeable symptoms of any kind. I pulled over and checked my belts and fluids and made sure my plugs and wires were tight, all good.
Took it to an AutoReillysAdvance in the next city and they said the meter wasn't finding my sensor at all. Tried the next store, same thing. The scanner wouldn't connect.
Drove it 400 miles home with no symptoms. Today I took it to another place, same issues, he says it's probably a blown fuse somewhere.
Do our Vibes have a diagnostic fuse that can blow? Or why the heck can't my CEL get read?
