Title: Help needed please-Auto Trans giving P1625 code ?
Post by: SJKOO01 on 18 May 2009, 18:10:14

Hi all.

In my other thread I originally thought I had an engine problem as my engine light came on, on the dash;


http://www.omegaowners.com/forum/YaBB.pl?num=1242505053/0#0


However, today going to work & coming home the light didn't come on.
But bought myself a code reader anyhow. There nothing showing in the engine codes, but out of curiosity I thought I would check the Auto trans codes to see if there was anything in there;

P1625 has shown up. Does anyone have an idea of what the problem may be in the transmission, as there's no noticeable problems at the moment - I'm totally confused by the engine light showing on the dash, going off, then finding I've a transmission problem ??????  :o ,

Help please as need a car to get about in very much !

Lots of measuring to be done, looks to be related around Pressure Regulator, so find that on your wiring diags, and take some measurements

Have to admit, I'm very much a numpty when it comes to electric on a car.
Found in my haynes manual refererance to "Solenoid - main fluid pressure control" (U10.2) in the list, is this the same thing as Pressure Regulator ?.

Now just got to find it on the tiny diagrams ?!.

Regards to above, can only find something relating to solenoid - main fluid pressure control, and that looks like it maybe to do with the ECU if I'm reading the diagrams right ??.

Is there a pressure regulator actually physically fixed to the gear box that is known to be problematic at all ?.

Sorry, had to post quickly earlier as the battery had died in the lappy.

The pressure reg will be in gearbox, so find its connector, and take some meaurements.

No problems with delay, as I've been trying to find wires on wiring circuit anyway, no luck so far.

What kind of measurements am I looking for / needing to do ?.
Am I looking for something called an open circuit or looking for voltage readings.

Would you mind explaining what I need to look for, I can get a friend who understands electrics better to help out then.

Sounds like this is going to be expensive for me again though ?!.  :-[

"force motor/aka solenoid" is located in the front sump on  the steering wheel side.

Thanks for advice. Will take a look this wk/end to see if I can get any readings and post them when I do.

Thanks to those who've helped with advice.

Apologies for bringing this to the front again.

Haven't managed to get the readings, as can't find a way to 'patch in' to the loom as don't know where to start ?.

Also as I'm not electrical techy, what am I looking for, readings show consistance, or readings regards to volts measurement ?.

Any advise on where to start would be greatly received thanks.
