Nissan D22 Y25 DDTi Pickup - Rough running in 4th gear only - Fixed #

Posted by Andy Mason on June 11, 2011, 10:41 am

Year of Manufacture *: 2003
Engine Size and Code *: Y25DDTi
( Optional) Fault Codes: No fault codes

Really weird fault. No fault codes with numerous scanners used.
vehicle drives perfectly when cold, when hot it hesitates/misfires and lacks power, but only in 4th gear.
We have blanked off EGR valve, but no differance.
Obviously we have checked for air leaks etc, vehicle does'nt smoke and starts perfectly.
There are 4 sensors on gearbox and transfer box, but as far as we know, they are reverse lamp and neutral switches on gearbox and 4wd and neutral switches on tranfer box.
Any ideas greatly received, many thanks Andy

Seen a few, in live data on the road you can see neutral going in and out, hold gear stick to left or right, can't remember and it's ok.

I will second that, look at the gearbox switches.

I have replaced a couple for the same fault.

I've just had the same fault on a 2003 D22. I knew I had read something on here & even ordered the switch after only speaking to the customer on the phone. I found the job easier by removing the gear lever gaiter as you can't get a spanner on the switch from underneath. (part number 32006-23U6A, about £60+vat) Thankyou guys!

I wish i knew about this a couple of years ago..

Ended up fitting new filter, running from fuel can and trying..

Then removing injectors and getting them tested..

Then removing coded pump and getting tested...
And so call repaired!!

Replaced pump to find it even worse>>!! £1000 later.

Then found out about switch problem and sorted it but engine was now underpowered so removed pump again and sent back to find them say there was nothing wrong with it,!! Replaced it to find it was then good.

2 months after original problem its fixed.
what a b***ache it was.. cost us a fortune for a £60 switch..
just shows the forums can save a load of hastle and money.. It was the now long gone Ilexa forum that helped me!
