CEL staying on with no faulty codes showing on Bugeye
Hi, My car's check engine light has been on for the past month, it does go of for a little while but instantly comes back on and tends to stay on ,whilst flashing a few times as well.My cousin has a fault code reader but nothing no cel error codes when plugged in ,so really confused.Car seems to drive well with no noticeable power loss.Any help would be great cheers

Cheers pal will give it a go.but the car was out of action for a few days only 2 weeks ago whilst waiting for a new battery to be delivered,since new batt fitted the cel has come back on, not straight away but after a short local drive

Bugeye stores error codes on EPROM so you have to actively clear with Select Monitor / SECS / OBD reader........disconnecting the battery resets the learning side of the ECU like the AIM.
Get your cousin to check for historic codes stored on the ECU.

I had exactly the same problem with my Blobeye, CEL light flashing then staying on permanently with no error codes. Turns out to be the Neutral position switch.

NPS problems generally leave historic misfire CELS. Camboflip, there is no specific sensor for the CEL light. The ECU monitors a shed load of things and then lights the CEL or makes it flash to bring something to your attention.
Which for the DENSO bug ECU can be a bit frustrating as it can go off randomly, usually the camshaft position sensor or the neutral position switch

I got the local mobile mechanic to change mine, only charged me a tenner.
The switch itself isn't that expensive.
Take it yours is a WRX?

I've got a WRX with a 6 speed gearbox.......mainly because the 5 speed kept breaking at over 400 BHP LOL
You need to drop the 6 speed box to change the NPS which is a bit of a pain.
However, you need to do a shed load of mods to a WRX to need a 6 speed box......maybe it's something else?
Usually by then you have changed the ECU and the CEL might be lit by a SIMTEK etc detecting knock........
Just curious why your bug WRX needs a 6 speed box...........

Its our project ,plan to make it a quick car and to be tracked every month.have broke the transmission on one other car before,non subaru,so didn't want it happening again,plus had a very good deal on the 6speed, a guy from sutton Coldfield was breaking his sti 9 and sold it cheap(cash deal)

In general if you like to have fun in a wrx the brakes, suspension and gearbox if your aggressive in gears 1,2&3 than these will need changing.never liked being brutal in 1st and2nd on 5speed so lost out to many slower but quick cars in these gears
