+18 2007 Mx-5 Check Engine Light References. There is no correct answer here and you need a o2 sensor socket to remove the o2 sensor. Be interesting to read the codes and see what has tripped it.

Had to drive about 20 miles so did, car ran fine. If your car has a flashing check engine light, it means you need to service the engine now. Turned off, checked gas cap and restarted, still on.
