P0700 in engine ecu, and P1625 in TCM?

If so, I'd be guessing a solenoid failure in gearbox.

0700 is just a request from autobox to illuminate MIL.  All I can find on 1625 relates to an electrical short (to ECU maybe???).
Short to voltage in circuit to control unit terminal 52, 5

There are 3 different codes for P1625. So not necessarily a short. Could be open circuit as well.

TIS states
Final stage diagnosis in control unit
Short to voltage in circuit to control unit terminal 52, 5
Above condition must be fulfilled for at least 0.02 s .
Effect:

"Emergency Mode" is activated
The malfunction indication is switched on.
Concerned Terminals:
52, 5

the Solenoid

Nothing to do with it

Really , Nothing to do with the pressure control solenoid then?

P0748

Eh?

Check the other 2 for P1625 as well

Oh I see now, so the P1625 is linked an Autobox fault which in turn throws up the P0700 code when any fault around the box is detected.

With regards to the lights, the "spanner" light initialy came on when driving then went into limp mode, after pulling over and turning the car off and on a few times it cleared the limp mode and the "spanner" light went off but the "engine" light then came on and has been on constantly since but hasn't gone into limp mode since, like I say the car itself drives lovely doesn't miss a beat.

Is the pressure control solenoid within the gear box itself and is it an expensive job to fix?

Appriciate the comments thanks.

Can`t, no access

Fault code implicates U10.3, or its wiring (going back to pins 52 and 5)

Thanks for the reply's guys,

Pigging me off even more today as the temp gauge has now decided to stop working, was working fine before this Auto Electrician started fiddling with stuff yesterday and after he'd read the codes.

Thought it might just be a dodgy fuse but after flicking through the manual I don't think there is a fuse for this is there?

Any ideas where to look please? I don't think anything was disconnected but he was under the bonnet for some time but I think that was to do with the oxygen sensor or something??!?!?!?!

[TheBoy]

Think 2.2 has same spade connector setup for the temp gauge as V6. Hopefully a 2.2 owner can say where it is

[RobG]

Rear of the head next to EGR valve. Pic is of the 2.0 so OP won`t have the dispack

[marshall76]

Thanks for replys and diagram, I'll need to get someone to take a look at it, I wouldn't know where to start to be honest. I've been out to take a look but not entirley sure what I'm meant to be doing.

Is it just the case of making sure the connector is in place on the dash board temp gauge sender or isn't corroded. He was fidling a bit round the back of the head - like I say I'm no mechanic what so ever so this is all new to me.

Taking the car back to the Auto Electrician this week sometime,

I'm a bit torn now as to which direction to go with this either the gear box or electrical circuit or the emmisions now 

I've printed the wiring diagram off (which I havn't a clue where to start with this) but I'll give this to the guy who's taking a look and hopefully he can make sence of it.

If he doesn't come up with any solution I will probably go by "theboys" recomendation and take it to somebody off here to look at and get put right.

[marshall76]

Popped into see the Auto Electrician earlier this morning before work just to show him the wiring diagram and offer some ideas of what it might be, he basically disregarded everything I said about checking the continuity from Gearbox to ECU and every other thing I mentioned, I also mentioned emmisions and he said boll*cks it would come up with "emmisions" when I plugged the fault reader into it!?!? He was supposed to do some research too on the P1625 error but said he couldn't find a thing anywhere on it so think he was a bit put out that I had.
As the father in law has known this guy for years he wants me to book it in there for the day which I'm a bit dubious about doing I just bit my lip and said "Well your paying the bill then and make sure he fixes the temp gauge he knackered when he was fiddling last week".

Me personally I'd rather pay somebody on here who lives pretty local to the South Yorkshire area who knows what there doing to take a look because I havn't a clue where to start looking but I guess I'll see how this other guy gets on, think it's booked in Friday.
