It is a crankshaft sensor / cam position sensor correlation error. In otherwords the sensor in your distributor that reports the position of the cam shaft and the crankshaft position sensor behind the harmonic balancer are not in synch. The most common cause is a distributor being removed and replaced a bit off. Second would be wear of the distributor gear and third would be excessive slack/wear of the timing chain and gears. last but not least would be a bad sensor or wires from the sensor. If you have had the distributor removed for any reason re doing that at top dead center is reccomended. If not check the distributor gear for wear. You can test for wear by turning the distributor counter clockwise a degree or two and see if the code goes away. If this test is successfull replace the gear soon as it also drives your oil pump!! This is done properly with a scan tool that can report cam position while running at 1,200 rpm it should be 0.
