OK Ignore the above post.
I tested it again. Engnies Temp was about 40 degrees. With key on engine off current is +59ma . The service manual addition for the (2.3) 16v engine states 50ma at 20 degrees. So it's not miles off but a little perhaps.
At idle it's exactly 0ma.
Opening the throttle makes it jump to +40ma or so.
As the revs come down it goes to -50ma (Deceleration shutoff)
So that seems to be functioning about right or not miles off. Resistance was 20.5 ohms, a little over spec of 19.5 ohms but not a problem?
I did notice, when I accidentally left the engine temperature sensor disconnected and went for a drive, that the response problem was magnified. I suppose this is expected and doesn't tell me much?
It's annoying me a lot
