Hello I'm a newbie, I have looked to try and find the DTC codes for A7 and from the Volvo pdf files I've got some, but not one of the two logged on my car.

I have:

2-3-1 (Unknown)

1-2-2 (Temp. Sensor/Interval Too Long?)

I cannot clear these, so I presume they are current faults?

Can anyone assist by telling me what 2-3-1 is?

Many thanks

0231 = Fuel Pump Secondary Circuit Low
0122 = TPS/Pedal Position Sensor A Circuit Low Input

Those are from the generic OBD2 codes, at P input.

OBD I or II? On a '94 it could be either, or both. I'm assuming the codes are different, but I guess I shouldn't assume. OBD I codes can be found here ----> http://www.troublecodes.net/Volvo/

I don't know about OBD II. Maybe someone else has a link to a list.

Hmm well that site says 89-93, mine is a 1994 but OBD I...

According to that site that'd be:

122 Lambda adjustment
231 Heated Oxygen sesnor(lean mixture/part throttle) 94-up

Fuel and ignition systems show no DTCs.

Only other DTCs are on ABS and I can't clear those either!

1994 should be OBD1.
However, the difference in the error message may be due to the generic versus Volvo-only codes.

Thanks.
