Engine yellow light on not flashing

[bunch1980]

Hi, All, so have not been on here in ages, as ever things gone crazy, and have been enjoying just driving the car when I can, its used even less now cycling to work to! did about 650 miles only last year!
Any how went to site for work today to do a survey, after going to local shop the yellow engine light is on but not flashing, back home no error/trouble codes showing on OBD thing on iphone app.
Sure before I had previous codes shown to but its been a while since I have used it.

Flashing would mean a misfire.

Steady ON, with the engine running, means there's a code (or more than one) you need to read.

What app are you using?

[bunch1980]

Thanks Dave, its on iphone, EOBD-Facile connected via wifi, seemed to work ok before, does engine need to be on to use?

[bunch1980]

The ignition needs to be On and best if the engine is running

Hardly drove less than usual due to lockdown, got thingy to work to show code today, is this anything to worry about, i think its the system that comes on when it starts or is it on all the time? not sure of second code at all!
Car appeared to run as per usual and not issues getting up to speed at all honest officer

Pretty sure I had that p2259 code for ages. As I understood it, it was due to a secondary fan to get the cat up to temperature.... Didn't affect the drive at all. No limp mode or anything for me.

I'll try to see how I solved it but think it was a case of just taking out the connector, spraying the connector with contact cleaner and reconnecting. The wire connects just behind the intake, and can be reached by those with smaller hands and slimmer fingers than mine.

I'll look through my pack of service stuff with my rx8 if i get time tomorrow and see if I can find out anything more specific as to how I solved it.

If you had cat air pump think removed from the engine bay you have to to map the ecu

[bunch1980]

Thanks for replies all, will look at connector and see if anything else amiss, not had anything removed as far as i know.

Anyone know what U0073 is?

Canbus interupt I think. My odb2 reader sets it off from time to time. Usually got on restart.

Starting the engine with an OBD transmitter connected can on some occasions upset the ECUs check routine.

I have P2259 pop up when I restart the car whilst its hot, then it randomly goes out at some point down the road. Was going to replace the solenoids but will try this first, lot less work than taking the intake off to change parts! Certainly has never made any difference to the drive at all.

[v-rex]

I'm pretty sure that I didn't replace the solenoid to fix this, although could be wrong. I'll try to check later in my pack but today has been mayhem for me as usual.

I am sure I read on another rx8 forum, that the wire for this has to go in at an odd angle and due to heat etc can become loose or something.

Pretty sure that it was a case of disconnecting and replacing. I remember it being a blue connector and and in the middle of 3 similar connectors.

Update, after finally getting battery charged and going for drive, started first time fast to, and now no engine light on at all!
I had posted in other thread about selling but am leaning towards keeping must be mad!
How does she sound in vid, is it just me or is very tappety noise?

[ChrisHolmes]

That’s your SSV valve rattling. Increase the revs slightly and it will stop? If you reach in ( be mindful of the belts on the running engine )and press the arm with your finger it will stop. Both the previous actions will confirm my comment.
Fitting a piece of rubber tube to the stop pin will cancel it out.
Nothing to worry about.

Get your battery cover back on when you can too. It'll work better and last longer.

[bunch1980]

Thanks both, do you know I think I asked similar when got it, its been so long since listened with bonnet up etc!
Do have a cover bought off Bigpete yonks ago to, need to see how it fits.
