    Nissan Patrol 1998: How to adjust idle speed?

    Nissan Nissan Advice Nissan Patrol Nissan Patrol Advice Nissan Patrol 1998

    I would like your advice on how to adjust the idle speed of my 1998 Nissan Patrol diesel turbo. The recommended idle speed for 4x4 is 650, but mine is at 800. The engine has a drive-by-wire throttle system, so I have trouble adjusting the idle speed and do not know where I should look.

    According to Nissan the correct idle sped for your Patrol is between 750 and 800 revs, so your vehicle is within specification. Nissan says you can't adjust the idle speed manually as it is controlled by the electronic control module (ECM) and must be checked by a Nissan dealer. If you have any further concerns, a diagnostic check by a Nissan dealer can establish if there is a problem, and if so, which sensor is causing the variation in the idle speed.
