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.

It is impossible to tell without a code reader. I would pop into Mazda and get the codes then take it from there

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...

SOURCE: First: alarm went off on its own.(mazda 6 2003).

there is often a small back up battery in the immobiliser unit itself, if you can locate this unit and replace the battery with the ignition on / engine running, then it should not need recoding and work fine after that. The other thing that could be wrong is the key battery (if the fob has one) or the transponder chip in the key head. If the key signal is low the immobiliser lamp will light during driving, but this does not explain the alarm going off. That is more likely either a poor vehicle battery, alarm / immobiliser back up battery, or another electrical fault such as water leakage into a tail-light or even the alarm unit itself when it rains. A lot of alarms are voltage sensing and when the vehicle is parked they will alarm if the battery voltage changes for any reason, though not during driving so the battery in the immob is my first choice to look at.

Why wont my car start even after i tried the security reset. i turned key to on position for 10 minutes turned it off then tried to start it 3 times. security light still flashes


turn the key on and wait till the security light stops flashing ( this could take as long as 30 minuets ) then turn the key off then back on but do not try to start the engine and wait till the security light stops flashing ( again this could take as long as 30 minuets ) then turn key off then turn key on and start engine.

Have just purchased a 2006 Mazda 6 Atenza and noticed that there is a light on the dashboard that is continually blinking - it is a car with a key symbol in it. I refered to the manual but it is in...


This symbol is normally the car electronic immobiliser symbol and should not be lit once the car is started.

If it keeps on flashing and the electronic immobiliser is installed properly, it will prevent your car from being started.

Flashing symbols means immobiliser code is invalid or uncoded.
Hope the information is useful.
