1991 Loyale CHECK ENGINE light

[John Galt]

Hello,
I have a 1990 loyale with about 165,000 miles on it. The other
day the check engine light came on, and has stayed on ever since. The
oil pressure is good, and the temperature is good. Can anyone tell me
what else could cause this light to go on?

thanks,
Flank

See the lists here:

There are several thousand things that can set a code. Without a code reader
you could spend a lot of time and money guessing at which one set the light.
At 165,000 miles could be oxygen sensors, catalytic converter, or loose gas
cap. Too many to guess at.

Sorry, you have a 1990 or 1991 which was before OBDII. There are ways to
pull the code on the OBDI cars.

Here is the info on reading the codes for OBDI and a code list:

Also do a goggle search for "subaru trouble codes".

Blair,
The page you suggested is for a Legacy, not a Loyale. Is the
wiring compatible?

thanks

in the code lists:
