|
|
Hi
I spent some time searching this forum but found any info about those lambda sensors.
Could you please point me out to the topic if any exist? Thank you.
I have found one sensor in the middle of exhaust system but I guess there should be one more closer to the engine?
It`s 3 L V6 petrol, 2005 Active Field.
Computer was connected to the truck but found no faults. It`s not really reliable because those data bases has no Delica present.
The problem appeared at the Pay and Play when went quite hard up the hill and over the edge.
The engine was shaking a bit and not smooth at the idle.
The fuel filter was replaced like two weeks before that, so was thinking might be about injectors chocked?
It looks, there is no false air, filter is clean...
The next thing are lambda sensors to be checked. There is no check engine displayed but have read that it might not appear.
The fuel consumption went up from 20 L to 27 L / 100 miles
Any help very welcome please!
Thank you. |

Can you check for running rich, like see if the exhaust pipe has soot in it
Or the M.A.F. sense & control. Long time back, I seem to recall some makes of cars having early-ish failures with that part.
If the Lambda is cheap enough, might be worth replacing.
Dunno if this will help - Way back, friend of mine had a Merc 220 SE, It was misbehaving.
We could not find the problem, I had an idea, at night time, find a dark place, look at the engine -
There showed the problem - - A firework display, from the HT leads
Might help
