Hi All,

Just chasing some advise or if anyone has a similar issue?

Last week my Patrol (2002 GU2 Zd30 DI) went into limp mode whilst my wife was driving it.
When I inspected found that the engine was idling at about 1000rpm and sometimes just above. Coupled with the A/T Temp sensor coming up intermittently (even though the car is a manual). Test drove and felt like speed indicated on speedo was incorrect.
Can someone point me in the right direction of what to check?

So far I have: Disconnected the batteries for over 24hrs thinking ECM reset. Reconnected and no change. I know the Trans temp sensor and speed sensor run on the same common wire - possible short or rub through maybe?

Any advice would be greatly appreciated.

Cheers

Woody
