limp mode. engine code is P0891 help!
 

Hi.
My grand voyager 2.8 (2005) has gone into limp mode with engine management light on. We have had it read and it's come up with code P0891 meaning TCM power relay sensor circuit high. Any ideas what or how to fix as currently I'm without a car and meant to be leaving for the airport in a week!
I don't want to be ripped off by any garage as so far I've been told relay switch, shift solenoid and also new gearbox!! Help please.
Thanks in advance

There doesn't seem to be a P0891 on the Allpar Code site but 800's are relating to Auto-box. Tech boys on here should reason this.

Fault finding procedure for p0891 can be found in this document

It will either be a cheap easy fix of wiring or a relay or an expensive EATX module
