Diagnostic codes L & J?

[btom]

Any ideas guys?
Have had both these popup in the last couple of days and want to know if anyone actually knows what they mean before I commit to taking the car back to the dealer.

All codes are:
A - Speedo sensor not activating zero switch or switch broken
B - Speedo sensor not releasing zero switch or switch broken
C - Water level sensor not activating zero switch or switch broken
D - Water level sensor not releasing zero switch or switch broken
E - Fuel level sensor not activating zero switch or switch broken
F - Fuel level sensor not releasing zero switch or switch broken
G - Water level sensor open circuit
H - Air temp sensor open circuit
I - Oil temp sensor open circuit
J - Oil pressure sensor open circuit
K - Fuel level sensor open circuit
L - Erratic road speed sensor input
O - No communications between analogue and control

L - Looks like you have either a poor connection to the speed sensor, incorrect gap setting on the probe or its goosed. (The probe is gapped to a toothed wheel on the rear diff).

J - I had this on mine, it turned out to be a loose connection on the oil pressure sensor.

Thanks Graham,
Suspected that one of them would be connected to the oil as the PSI reading jumps about.
BTW are those definations in your manual? - they aren't in mine,

The info came from elsewhere within these hallowed pages...general consensus seems that they are accurate.
