Thank you for your kind help. as for MorganM's suggestion, actually I read the trouble code ,the number is #45, atomospheric pressure sensor,and the engine light is keeping on. So I have a little worry on that. Also ,I appreciate legacy777's words , do you think I need not to care that too much? Happy new year! best wishes guoqing

Could you tell me the location of atmospheric pressure sensor in my 1991 legacy wagon subaru? a experienced technician said only replace whole ECU. However, I saw some webpage I can set sensor to over 760mmHg. some people know that? thank you very much guoqing

thank you very much.

my 1991 subaru works worse. When I pedel the accelerator steadily, noise(surge or whirling) occurs sometimes then it will go off. what's possible reasion for that? I appreciate for kind reply.

hi, my 1991 non-turbo wagon works well but check light on. The trouble code is #45,atmospheric pressure sensor-faulty sensor. So, what's possible reseason for that? I appreciate for kind instruction. I also try to clear the code with battery out and fuse disconnection, neither of such ways work. What's should I do then? guoqing
