Little Jimny (soft top, older cam belt engine) failed MOT on emissions, does any one know if the manifold and cat lambda sensors are the same part and if they're the same part for the two engines (cam belt and cam chain) as I could try swapping lambdas with Big Jimny (cam chain) which passed?
I did notice when I got home the earth wire from the bulkhead to the top of the engine was disconnected, would this be likely to affect the lambdas?
MarkyP what do you mean by "scope it"?
Cheers
John.
PS no engine management light on.
On the 8th Day God made the LandRover -
On the 9th day he swapped it for a Jimny.
The missing earth wire could well effect the reading however its worth putting a new sensor in anyway if it hasn't been changed for a while as they do slow down with age.
'Scope it' means to put an oscilloscope on the signal and check the reaction time.
No jimny should fail the cat test/emissions test reason being there is no limit guidence in the mot testers emissions data book tell then to check in the book and it then has a standerd co test so the co no more than 3.5% hc no more than 2000 ppm and the lambda doent get tested
For some reson a lot of soft tops fail cat tests hut the hard tops pass
