found a second hand one and replaced it and all is working fine once again
PS i also saw that if you soak the o2 sensor in liquid toilet cleaner it can revive them , so i will try that with the old one and see what happens.

there's probably nothing wrong with them Richard, other than they don't ship outside the uk. the cheapest i found was rimmers but they charge you twice for postage so a $210 dollar purchase ends up being nearly $400 with tax and postage

so i have spent 2 days trying to find the right o2 sensor , have found some that are identical even with the right plug but they are 1v not 5v . todays o2 sensors are all 1v switching basically , where the rover is 5v switching with 4 wires . the cheapest 02 sensors that i found are at rimmers for $103 plus postage and vat tax make it $180 odd , so not really any cheaper . $50 dollars to post something that will fit in a small box is a bit rich . so i am now trying to find a second hand one .

hi Pete, i looked at the numbers but they don't say anything about the actual units other than their designation. on the ecu that i found in the shed it says that it's an 8.2 ECU , where the others are just 8 ECU . it doesn't make any reference to say it is with o2 sensors or not , i haven't found any info on them or any differences in them other than the year.
does anyone have an electrical diagram of an 02 05 Subaru forester that shows the o2 sensor pin out . the sensor are identical , even the 4 wires . if you are wondering why i am doing this it's simply the cost , the subaru ones are as cheap as $40 dollars compared to $250 dollars for genuine ones.

that's interesting for the ecu's , i thought they was a difference . i have just acquired another rover , this one is a running registered vehicle with EAS, so I'm just welcoming myself to the world of EAS issues now , fun. i haven't looked to see if this one has o2 sensors yet but i will and put the nano on and look for differences after the weekend thou.

i understand where your coming from Richard , the cars i have are all 4.6L and mine is a 4.0l . I think i have another ecu in the shed that might be a 4.0l , will have a look . i have done some cross checking and have found that Subaru's have the same type off o2 sensors but i dont know if they are interchangeable thou. has anyone else looked at different replacements for the o2 sensors.

simple question , can you bypass the O2 sensor system. i have 3 wrecks and none of them have O2 sensors , so can i bypass the O2 system on a 97 gems.

to pull the fuse takes the power out of the system , lifting the sensor only disables the system , everything still has power so if it's still a problem it should be easier to find as it's not supposed to work, maybe.
the alarm should read ABS Fault on the dash ,nothing else.

dumb question , but have you lifted just one sensor and see if you get ABS fault on the dash , this disables abs and traction control so it should just have standard brakes . if you still have troubles lift them all and eliminate the sensors . so if it's something else you can look elsewhere.

dose it rattle when the window is fully up and fully down when you close it , dose it still rattle if you push on the glass to shut it .

if you want to check your suspension you will need another person to move the steering wheel (eg wife) while you physically put your hand on every joint possible looking for movement , also grab hold of the wheel and rattle the crap out of it (from the top and the side) whilst feeling the upper and lower ball joints in both direct and on full lock position. the vehicle needs to be on the ground in the running position , you only move the steering wheel about an inch either way .
PS check your shocks rubbers they can cause clucks and bangs to

just knock of the lumppy bits and use whats left to help put the skin back on

We used to have those around here too, but not in 20+ years. I suspected not enough people worked on their own cars anymore to make such a place pay for itself.

the trouble Harv is there is nothing on today's cars to fix , disposable like every other thing now days.

another thing to check if you haven't already looked is the strip on the roof , just lift it up and look for a hole or missing mastic on the seal under it .

that looks more like condensation more than a leak , i would wipe it up dry and leave it in the weather to see where the moisture is coming from before you do anything destructive.

it's been a while but i finally got around to doing my A/C, went and got it recharged (200$) , also took a tiranny switch with me , but i didn't need it but if i didn't i would have needed it of coarse . put some dye in it for prosperity , just in case it desides to disappear on me .
PS my daughter is getting married on the weekend and didn't want her make up to run in the heat so i sort of had to fix it .

some of us are from Australia to , welcome to the pub.

thanks for the comment Harv , straight to the problem, blown fuse under the bonnet . i am refreshing an old rover for my daughter's wedding soon, have been cleaning it up for registration . lets hope the fuse didn't blow for a reason , thanks.

hi Harv just gave it a run , didn't work , every thing else worked but it will not communicate with the air bag system . just comes up with, unable to communicate with ecm.

as it states the nano will not connect to the ecm but it will connect to the becm. this is a friend's car he has asked to fix air bag issue but i cannot connect to read the fault . where is the best place to start .
