Tip of the Day: ‘Check Engine’ Light Really Does Mean ‘Check Engine’!

by Eubie on May 1, 2014

We stumbled upon this heads up and it interested us because our ‘check engine’ light has been blazing hot for about five years now. So says the Wizard, the light means you might have one of these problems:

1) Bad oxygen sensor

2) Bad (loose) fuel cap

3) Older model catalytic converter

4) Bum spark plugs and wires

5) Busted mass air flow (MAF) sensor

6) Worn out ignition coil(s)

7) Battery trouble

8) Bad Exhaust Gas Recirculation (EGR) Valve or gunky EGR ports

9) Faulty vacuum hose
