Engine light remains on. - 2004 Mazda RX-8

Yes, It goes through it's initial checks before the lights go out,
If the lights stay on that means a problem has occured

May need a new oil pressure switch,it's located next to oil filter,remove electrical connector then part.You may have to remove oil filter to remove part.

You need at list a code reader to start. Read the code so I can help you. Let me know what code you have.

see this steps and fix it. God bless you
The Check Engine Light (which is actually the Malfunction Indicator Lamp or MIL) alerts you when an emissions-related problem occurs with the engine control system or emission controls on your vehicle. Depending on the nature of the problem, the Check Engine Light may come on and remain on continuously or flash. Some intermittent problems will make the Check Engine Light come on only while the fault is occurring (such as engine misfire). The Check Engine light usually remains on once a fault has been detected, and will remain on to remind you that a problem has occurred that needs to be investigated.
An illuminated Check Engine Light can be annoying because you don't know what's wrong, and whether or not the problem might be a serious one or just a minor fault. There is no way to know what the problem is until you plug a scan tool into the vehicle's diagnostic connector and read out the code(s) that turned the light on.
If no other warning lights are on, and the engine seems to be running normally (no unusual noises, smells, vibrations, etc.), you can assume the fault that is causing the Check Engine Light to come on is probably minor and won't hinder your ability to continue driving. But if other warning lights are on, you should probably stop and investigate the problem.
When the Check Engine Light comes on, a diagnostic trouble code (DTC) is recorded in the powertrain control module (PCM) memory that corresponds to the fault. Some problems can generate more than one trouble code, and some vehicles may have multiple problems that set multiple trouble codes.

The problem that the check engine light is reporting will have to be fixed, for the light to remain off. Have the trouble codes read to find out what the problem is. Then, the light can be reset with a code scanner and should remain off if no trouble codes exist.

No you need to have the vehicle scanned for the check engine light to see what the code is that has it on. Autozone will do this for free.

Hi there,

The yellow/orange Engine Check Light is an indicator that your vehicle's computer has detected an abnormality within the engine's electronics or emission system.

Sometimes it can be a one-off abnormality, which eventually rectifies itself within 40 drive cycles.

However, if the Engine light remains lit, then this is an indication of something more concerning (but not necessarily serious).

If it does remain lit when driving, then you should have your local Jaguar service agent scan the computer for "trouble codes", which will quickly identify the component and/or location of the problem.


Hope this helps...


Cheers,

Have you scanned the codes? You need to find out why the light is on and correct the problem. After fixing the cause, the code reader may be able to clear the codes, if not try diconnecting the battery for 20mins to 1/2 hour.

Definately the brake light switch,locatedabove the brake pedal (may need to drop the lower facia panel) switch may need replacing or more than likely adjusting. new switch about £10. Good luck Davelee
