Engine Light Comes On

[vmax]

My wife says the engine light comes on occasionally on her r33 gtr .Any ideas what it could be?

Cheers

Could be multiple things, any other symptoms other than just the light coming on? If it comes on and she doesn't notice any differences in how the car drives, it could be anything from low oil pressure (BAD thing), engine knock (she might not notice the sound that comes with this problem) or just sensors stuffing up.

I know my HICAS light comes on a lot when driving back from Sydney, but I am 99% sure there is nothing wrong with it.

If neither of you know anything more than the fact that the light comes on occasionally, I'd recommend either taking it to somewhere like Trojan Motorsports in Mitchell, or Autotech in Hume....otherwise perhaps you should swap cars for a week and see what you think yourself, try to pick up symptoms when it happens. Stop the car and listen to the engine with the bonet up, immediately look at oil pressure, water temp, etc etc

Hope that helps a little, but unfortunately a little more info is needed like trying to diagnose what someone's illness is when all the can tell you is "it hurts here" and points to themself

Small world David, I work with a friend of yours (fatz might ring a bell). Loving the vmax!

Does the engine light come on and stay on or does it flicker? Do you know if she noticed any other issues when the light comes on, like loss of power or anything?

probably knocking, if it comes on when your giving it a bit and flickers on and off then you need to use better fuel or booster.

Could be something easy and cheap or could be a warning of something more drastic waiting to occur. "Warning Will Robinson" ...lol....Sorry cant be more specific as others have mentioned what else is happening if anything. Need to diagnose and best to have someone qualified than 'hit n miss' gueses. Tuning was my issue when this light flickerd ie: knock sensor.

Your Engine light is flickeringing for a real reason in most cases - This light informs you when there is a problem anywhere in the vehicles Electronic Engine Control System. This system basically includes all sensors, solenoids, valves, actuators etc. that your vehicle needs to operate correctly. The system is big and can include both engine and/or transmission concerns.

Hook it up to a scan tool and retrieve the fault codes, may not show you the exact fault but will probably point you in the right direction.

Best way to do it is check the fault codes, write them down (reference no. and description, eg. P0205-O2 sensor open circuit), erase the codes, test drive it and recheck the codes and see which ones come back.
