I have just discovered that someone had taken out the bullb for the check engine light on my mates new my00 turbo so i have put one in and two fault codes have shown up (22 and 23) which i am going to sort out but i did not think that the check engine light usually stays on constantly? i have had the same two sensors go before on a my00 and the light only flicked on a couple of times. so why is it staying on this time? i have reset the ecu and its still the same. I will change the sensors anyway and see what happens.

if there is a constant fault with sensors or wiring then cel will be on constant.

on yours the sensors might have been intermittently breaking down? so light was only coming on intermittently?

 

Thanks mate i will get them changed then.
