I’m still waiting for Pocket Data Booklet and I have the following codes on my 1994 850 Turbo Sedan:

A2-143
A7-122
B1-325
B1-414
B2-122

Also I get NOTHING from either A6 or B6 jumpers - Is this normal?
There is no A5? (empty hole) Also B3 and B5?

If someone could look up the codes and give me the description/cause Id appreciate it very much.

Thanks

    With the 1-4-3 code, I realized I had a large crack in the main ICA air hose... Went to Volvo and picked up another. I know that will remedy the code, as I used electricians tape to temp. repair the other, and it's been fine for over 2 weeks.

    Check closely for vacuum leaks, especially if you hear whining sounds from the engine and below the dash...

    Good Luck

    A2-143 knock sensor(KS) signal, front, signal missing or faulty

    A7-122 engine coolant temperature (ECT) sensor interval too long

    B1-325 recirculation damper motor active too long

    B1-414 passenger's compartment, driver's side sensor intake fan blocked

    B2-122 speed has not been above 35 km/h or no vehicle speed signal

    All your gonna get from me are the code translations, I'm no tech.

    Good Luck,
