Hi FasrfordHi Steve
I've recently had my O2 sensors go on our 2002 GX RAV4
You'll be happy to know the on board diagnostic port is super easy to find !
It's underneath the steering column (UK car) down and to the right.
It's a white socket, looks similar to an old scart socket
Hope that helps mate
hi thanks but at min got no issues other than my aircon not working once car gets to running temp and maybe a prob with fans as they dont seem to be going at full speed in engine bay but till get some pennies saved cant do anything about those issues but good news is my engine temp stays at half way on gage so must be running okNo worries mate, I've just bought an obd2 reader off eBay for the vast sum of £8.90 !
Works a treat
I've ran it alongside a mates better reader and it picks up all the codes, although you have to google what they refer too, where as his more expensive one gives you an idea what the codes for.
I'm guessing your O2 sensors will be playing up if your check engine lights come on mate ?
May be able to help again if so
