I driving a 94 camaro with LT1, Auto trans.
I was driving when the engine died and would not restart. I went to pick it up the next day and the engine started. I had a buddy of mine check for error codes. Only one code was recorded. "Code 16 - low resolition failure". The engine seems to run fine now. What is the error code. I have done some research and i know it has to do with the distributor ignition.
Is this correct? what can i do to troubleshoot this problem?

Thanks for any help

 

DTC 16 means the PCM could not find the low resolution pulse signal from the OptiSpark distributor. When the PCM can't find that signal, it shuts down the fuel pump and injectors.

It is not unusual for this to appear as an "intermittent" problem, setting the code in storage when the PCM has a hard time finding the signal on startup. In your case, it sounds like the low res pulse signal was lost.

Check the Opti harness connectors.... both the one directly on the Opti, and the gray 4-pin on the bracket on the side of the intake manifold. If they are corroded, they can cause signal problems.

Another possibility is that something is starting to "blind" the LED emitter/receptor in the optical module in the Opti. It is fairly common for rust from the mild steel bearing retainer plate to build up on the sensor.
