Using Obd-2 Software

[tubaman]

Just hooked my 2002 1.8 VVti Avensis SR upto my laptop using my hardware (Elm) for reading the engine OBD-2 codes.

Not had any particular reason to & no fault codes showing but I`m only getting readings from 3 O2 sensors (I thought there were 4 O2 sensors on my model ?)

Any ideas - if there are only 3 O2 sensors on my model then clearly this is the reason for the readings.

Thanks

PS: If anyone is experienced with using this type of software (currently using Digimoto Lite & Scantool), are there any interesting things you can do with it eg.diagnose possible future problem areas or faults ?

Info I have would show sensors if 1ZZ-FE engine as follows. O/S 1, bank 1 - before cat. O/S 2 after cat. And lastly O/S 1 bank 2 - on 1ZZ-FE engine before cat. Would appear to be three in total?????

Wait for more postings, could well be wrong.
