The ref number for the manual is Technical Publication 32135/1
Section 2 ( 23 - 28 )
Engine management LH 2.4 LH 3.1 fuel ... EZK 116 Ignition
240 1989 - 1993
It covers :
Fault tracing
Design & Function
Repair
Maintenance
regarding your 3 codes , 322 is the burn off signal missing , but this is caused by your code 121 = air mass signal faulty/missing .
With the ignition on you should get 2.65 volts at pin 4 of the Air Mass Meter.
113 = Short term fuel trim signal fault , which is likely to be the lambda sensor .
With the engine idling and hot , the voltage from the sensor on the rubber shrouded connector should vary regularly about once a second from 0.1 volts to 0.9 volts should swing up and down .... ... an analogue meter is best for reading this .
Hope that helps ...

Belated thanks. Can I download that manual? From where? I can't find it, yet. Or does it have to be found
e.g. on eBay?
My 240 has no current fault codes, I think you are giving that information for someone else.
