I may be teaching my Grandmother to suck eggs, but have found the following, very useful, lengthy web site listing ALL Vauxhall models fault codes.

http://www.topbuzz.co.uk/info/fault_codes/fault_codes.htm

Thought this could help!

[philhoward]

Still didn't list 93 for a 2.0 16v....

[mantagte]

93 is immobiliser control module no signal
whatever that means

[philhoward]

I was told cam sensor!

Could be tricky on mine - no factory immobiliser i know of..?  Deffo no chip in my key and no keyfobs...uses an aftermarket alarm

[mantagte]

camshaft sensor is 92

[mantagte]

on my 95 20 16v i didnt think i had an immobiliser til the key fell to bits the key dioes not look like it comes to pieces but it does and there is a little chip inside as i think all omegas had an immobiliser fitted not all had alarms mine is aftermarket too
hope this helps

According to top buzz 93 is Hall Effect Switch.  

On a dizzyless engine the Hall Effect Sensors are camshaft and crankshaft sensors.

[mantagte]

93 hall effect switch is for a  bosch configured system the 2.0 16v uses the siemens setup so the codes are different

If there is a problem with the immobiliser the engine light will flash not stay lit.  

[philhoward]

It did flash when i had my "non-start"....looks like immobiliser, then!  Yes, it is a Simetc ECu, BTW...

topbuzz has a fair few errors, sadly.

for omega, use the ones from our Maintenence guides section, which are correct.
