First thing I learned when I got an F was "Be thankful for enthusiasts who reverse engineer the code reader kit, because a good ear, points file, and something to free off the mixture nut on an SU isn't going to cut it" 
Which reminds me, is there anything similar for this era of Volvo? |
I'm fairly certain the early K series had the knock sensor, can't quite remember my years but i think the F was 95-98 then repalced with the TF? You're lucky you've found a reverse engineered code reader, they're notoriously scarce!
When you say anything similar for this era of Volvo, i assume you mean some form of diagnostic kit?
If you lift the bonnet, you should find two small black boxes near the left hand suspension turret and bulkhead. Yours should be the LH-2.4 system so follow the destructions here for it :

As you'll (hopefully) find, a built in code reader! Be warned though, some faults can cause other codes to be generated so always worth a post to double check - for example a failed fuel pump causing an FTP will often throw a MAF or AICV code, sometimes Lambda sensor as well but not often.
Perfectly logical reasons for this - the system can't tell a failed fuel pump but it can tell that despite the ECU telling the AICV to open the engine spped and flow through the MAF hasn't increased, therefore one or both must be faulty - according to the ECUs limited "thinking".
In truth, the engine can't increase speed because there's no fuel getting through! Likewise it's getting no signal from the Lambda (which only works hot so the code only appears on a hot engine usually) so it assumes that isn't working either.
