Hi guys need a lil help with my uk 2000 impreza, i have a intermitent eml light on can happen when hot or cold and normally goes out within a min of coming on. car is running fine doesn't cut out and always starts. it loses a bit of power when the light is on.

I have read the code which is crankshaft sensor a range/performance problem. i have replaced the following with no difference to the light.
crankshaft sensor
cam belt kit ( as timing was half a tooth out)
checked the crank ring
checked the wiring from sensor to ecu
ecu
checked and cleaned earth tags

I'm running out of ideas anybody on here has similar problems or any ideas?

would the cam sensor affect the code?
many thanks
