Hi iam new here. Just bought my used 2.5L Diesel Pathfinder 2006 with 300,000kms.
Was good for few days then suddenly starts slow acceleration from take off.
When i first start it, it goes normal when i stop at a junction and try to take off from there it revs and moves after few seconds. i have noticed if i switch the engine off and start again it goes normal and repeats the above issue.
i scanned it with codes R1757 coming up. should i replace just the solenoids or complete valve body?
Looking forward for advice from guys who have had similar issues.
Thanks alot

Thanks, i went through that post and have emailed Roger.
i was suprised why after i off and start engine again it goes normal but i think it resets and goes into limp mode again if iam not mistaken. confused whether to change solenoid only or complete valve body

sounds like the solenoid can be hit or miss. May be worth trying for $70 each, vs $1000 for the whole valve body.

yes... iam in Fiji and have to import it from US so its a hussle. i might just order a complete valve body as its a gamble to try n replace the solenoid only.
Thanks

In my case is the valve body, they told me this is a usual problem on the pathfinders 1200usd the complete valve body in the dealer.
