Colorado 2010 3.0 ltr turbo diesel

Only on heated element air flow meters like the Nissan Patrol.

Grant,

This has been an occasional problem for some on the forum over a number of years. Think the fix was to remove offending sensor and clean with CRC carby cleaner. The problem seems to have occurred more often with the heavier foam filters, like Finer Filters etc.

Surprised you achieved an improvement in economy with the K&N, i've had one on a 79 series turbo, and any economy boost has been almost immeasureable. Fitted 3" Redback exhaust....now that's big difference!!!

Hope you're mobile soon, without any dramas,

Bob.

Bob,
Your worth more money, thank you for that info it worked!
Read your post then went out took the inter cooler off checked the inlet pipe and cleaned it checked the inter cooler it appears clean wiped the inlet and outlet anyway went to the outlet pipe took out the sensor which was a bit wet and dirty ( its above the inlet butterfly) cleaned it with turps (all I had) filled the pipe with a bit of two stroke petrol I had on hand and flushed/wiped it clean, disconnected the sensor on outlet of air box (clean as a whistle) put it all back together not much change left it idle and disconnected the air box sensor while motor running, engine revs went up, reved motor whilst sense disconnected and I would only rev to 1500/1600rpm replaced sensor and wow alls good took it around the block cruise control going again power back, reved it to 3000 only cleaned the lungs with a puf of grey and seams back to normal! Except engine light still on, will take it to local( J P diesel service) tomorrow and get it checked/adjusted.
Thank you for that info feeling much better

Grant

Just dont tell them what happened, then ask them what was the code in regards to the problem, then ask them to replace it under warranty, then you know it will be new and no possible after effects from using turps. Cant beat the genuine paper elements I reckon..................

Thanks for the endorsement, Grant. Glad to be able to help. Will email my boss's phone number shortly!!! LOL

Those K&N's don't seem to need much oil on them, but you might have to experiment to find out just how much. Their value in really dusty conditions is questionable too. Think paper rules, just check out any CAT machinery, it's all dry paper elements.

It's amazing how much dust a paper element can take, before becoming restrictive....it's heaps & heaps. The shortest time we ever got, on an elevating scraper, was 8 hrs. And that was in intense bulldust, where you could see the dust funnelling into the precleaner.

Blokes that clean 'em everyday, or even weekly, on their travels, are introducing more dust into the system than they're stopping. Ah, better get off my soap box, Grant.

Good it's mobile again,

Bob.
