'93 JGC DTC Code 12?????
 

My '93 JGC V-8 is reading out DTC Code 12. There is no such code in
the service manual. I checked it four times, so I am sure it is
reading 12. There is a Code 11, and I did have a problem starting the
other day. Code 11 is "No crank reference signal at PCM." That could
have been my problem, Anyone know about a Code 12? Could the PCM
just be a little mixed up and reading out the wrong (but close) code?
The Jeep was built in August 1992.

A '12' code is nothing, it usually means nothing more than the battery has
been disconnected sometime in the not too distant history. My Jeep has
maybe not had the '12' code 2-3 times in 7 years.
