Here is the problems.
Gas gauge does not always work.
Speedometer does not always work.
Battery charge light is on.
Error code 12. Problem with battery connection.
Error code 44. Battery temp in PCM.

I think all my problems are from a bad PCM, has anyone seen this before? Its the PCM or the wire harness.

Code 12 - battery has been disconnected within the last 50 key-on cycles (Nothing to worry about)
Code 44 - Battery temp sensor volts out of range (your battery sensor may be bad, it's in the battery tray on the right hand side if you are standing in front of the vehicle)

A COLD SOLDER JOINT? Will this because of a cold solder joint. I'll try the fix.


Now for the battery temp sensor, where can find one? Parts America doesn't show them as an item they carry. Is it a dealer only item?

Fix the cluster first, that may be whats setting off the battery sensor. You never know. The gauge cluster needs to be reflowed.

I just bought a 96 and i noticed after i use about 4 gallons the gas gauge goes to empty then dances up and down. The other problems havent showed up yet.
