Hi All,
i had the cel light comeon for about 30 sec while driving today, did the diag and got back..

24 - idle air control solenoid
32 - oxygen sensor
45 - presure sensor - pressure exchange solenoid valve

Should i perform a reset in the hope that these are 'old codes' stored, or is there anything there that could cause major problems if i dont replace.

 

As far as I'm aware, resetting your ECU won't hurt it, so you've nothing to lose. However, the fact your CEL has only just come on probably means that at least one of the faults detected is actually there. If you do reset, make sure you're patient whilst driving around, waiting for the CEL to illuminate, indicating reset. It seems to take forever, and even more so when you're driving around carefully...!

 

Reset, came back on and now i have just the one (for now):

32 - oxygen sensor

now the cel light only seems to come on when im trundeling along below 2-2.5k (most fo the time at the mo) and stays on for a while.

where could i get one of these from and are they a simple diy fit ( by simple diy im no mechanic but am happy doing minor things like services)

 

Glad you've only got the one error now! If you use the search facility, there are loads of threads regarding 02 sensor faults, and how to change. I don't think it's too difficult, but I personally haven't done it... Best of luck!
