Question about 2007 Mazda Speed 3 Hatchback

Check Engine Light comes on and off

Randall I have a 2007 Mazda 3 Hatchback. I have a problem with the check engine light. It comes on when i drive somewhere, turn off the car, and then start it again in a short amount of time. The previous owner installed an exhaust system and High powered headlights. I've had numerous dyagnostic tests done (Even from a Mazda Dealer) which have all ranged from buying a new computer, new battery, etc. I got a new battery and it continues to come on. What do you advise?

Head lights have nothing to do with check engine light.modifying exhaust if it has an EGR valve does turn the light on under acceleration.best is to not shut off the engine and read the code.

SOURCE: 1998 mazda 626 check engine light flashing

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. A technician will have to perform further testing to pinpoint cause and the proper repair. When the light starts flashing the computer is telling you to have the vehicle looked at now before other problems happen.

if i remember right if the battery light and check engine light is on, your alternators may be bad. your battery may just have enough to keep it running for a minute or so. you can take it out and get it tested at a auto parts store. or try charging your battery for awhile and see if it stays on longer. if this is completely wrong let me know

SOURCE: Check engine light intermittently flashing, car jerking.

Could be fuel or electrical related. Since you may not know the history, this may take a while.
Any amount of smoke from exhaust? White, Blue, Black?
Start with most obvious and inexpensive:
1. Fuel filer clogged (replace fuel filter).
2. Could be the ECM (Electronic Control Module). It controls the ignition spark timing.
A few other things... consider other expert solutions...

Oil pressure light keeps coming on/off after oil was changed at a Midas station


Ellen, check oil level immediately and top up if needed, if was low and light goes out, that was the problem and count yourself lucky that the engine did not blow. If oil level OK, take it into a shop for diagnoses before some thing bad happens to engine which could cost thousands of dollars.

check the ignition module, poss near the distributer for heatsink (contact) paste on the base to draw the heat away from the module. With the engine light coming on, it should have thrown a code possibly a bypass ignition or no pulse while cranking. If so refresh the ignition module.

Engine seized no oil did not get check oil or check engine light


The oil pressure warning light only comes on when oil pressure drops below 4psi at this moment there is no oil in the engine most often it does not get to this point because oil, water etc is checked every week. It could be your engine was using oil which would point to an engine fault.
