    Hhhhhhhhhhhhelp fault codes/warning lights

    Hi, I'm new to this so any help appreciated!

    I own a 2002 Astra SRI Turbo (petrol) and when coming home from work this morning after doing a night shift, weather being about -1.5 two lights came on my dash one being the car with a spanner - engine electronics/transmission electronics and the other being a square with a star in - electronically controlled engine cooling. I did as others have posted to get the fault codes and these came up as P1490 and P0530??? I have googled these but dont know what they actually mean!

    I have never had these come up before and have owned the car since brand new, it doesnt feel any different to drive ie no lagging etc.

    Does any one know why these would have come on, would it have anything to do with the weather being absolutly freezing and this affecting anything?
    Is it wise to drive the car while these lights are on ?

    Any answers would be great! Thanks

    P1490 Secondary Air Relief Solenoid Circuit Malfunction
    P0530 A/C Refrigerant Pressure Sensor Circuit Malfunction

    Disconnect the battery for 30mins that should reset the ecu and codes. Then take it for a drive and see if its ok.

    Thanks for the replys, i will disconnect battery and see what happens and let you know. What do you think caused these lights to come on though kev007, any ideas? Also, when i checked earlier i have slight leak coming from the pipe that feeds into the top of the coolent bottle. I havent been losing water like pikey20 said though only drips.
