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

What is ICA air hose ??? where is it located ?? how do I know what look like ?? I too have the same problem with code 143..


thanks

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,
