Distributor Ignition (DI) low resolution circuit


What does that mean?

 

It means the computer is losing the low resolution signal from the opti. Could either be the opti or the harness to it that is causing a problem.

 

If the engine is still running, its a "stored" code. Clear it (pull "PCM BAT" fuse for 30 seconds) and see how fast it comes back. If the engine isn't running, its "active" and you need to follow up on what Rob said.

 

Engine is running. I installed Headers and new plugs and wires about 2 months ago. My front O2 sensors are bad and I dont have rear O2's. Other than that engine seems to run fine, nothing out of the ordinary.
