Carina E Lambda Sensor

[dbaker]

Hello,

OK so I was given this carina E (australian import) 1.6 lean burn engine car which failed emissions. In my ignorance I believed the OBD which said there were no stored fault codes (lying SOB!) and then put on a new cat, which was pretty cheap.

Anyway, it still failed on CO because (I've now tested with an oscilloscope) the lambda sensor is basically 'on its way out'.

Does anyone know why a much cheaper 4 wire (heated) sensor can't be fitted instead of the stupid stupid price of the carina e sensor? The thing is I'd scrap the car rather than pay out- it would only be worth £400 max.

I understand that it has 'super whammy rapid heat up blah blah blah' but surely a normal 4 wire one would work?

I bet I'm missing something somewhere, and if anybody know I would be seriously gratful for any help!

Hi,

I don't know why they are expensive. But you might find the answer at this website:www.justlambda.co.uk. It might be expensive because it is a leanburn engine that has air/fuel ratio 22:1 instead of 14:1.

Don't worry I know now the people at www.gendan.co.uk were exceedingly helpful, and correct. They certainly do know their stuff!

actually- not that I am suggesting I would do anything of the sort or in any way....

but has anyone ever removed their air filter and had their car emissions tested...how much difference it made etc.

I.e. has anyone ever had a carina e with a duff lambda sensor whose OBD was such utter cak that it wouldn't even give a fault unless there was an open circuit in to the lambda...which makes the OBD look like a 'joke product', thus failing the MOT Co emissions- who then removed their air filter and had emissions checked, what was the values??

Had a thought about this you know- the carina E is a very environmentally damaging car- (this is a rant) I reckon if you've got a post 2001 Carina E lean burn with a 3 way cat and hence 2 quick warm lambda sensors...if your head gasket goes you'll be looking (from toyota) at over £1000 BEFORE they have even bothered to take the head off, cos in all likelyhood the glycol from the coland with have f**ked the cat and both lambda sensors, so if this happens and your cars SOOO ancient like 5 years old, scrap it. Cool. I love these new ideas from toyota

Hi ,

I'm having sudden problems with a 1.8i carina e 1996 since it came out of the non-toyota clutch fitters. Fine when it went in.

Engine light on and toyota dealer recons its lambda sensor. why?

hi, my carina e 1.6i just failed mot on emissions, went trough the internet looking for suggestions to the problem. turned out the lambda sensor could be on it`s way out as it is probably the original. not wanting to fork out the £2-300 for a new one i went to my local jap spares motor factor and behold £120.... and it was the correct one for the engine/transmission,year,lean burn blah blah. don`t get the universal fitting one. also bought new spark plugs and air filter. haven`t had it retested yet. but i`m optomistic. good luck.
