Either your distributor to crankshaft relationship moved enough to set the code while the engine was running or the distributor is in need of readjustment from plain old wear. You can't set it with a timing light, it takes a scanner. You would need to monitor Cam Sensor Retard above 2000 RPM and get it within three degrees of zero, with zero being optimal.

 

Hopefully you just need to readjust it to bring it withing specs. If it skipped a tooth or the timing chain is worn you have larger problems.
