Code Enable Criteria

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2001 Saturn SW2, 2001 Saturn SL2, 2001 Saturn SL1, 2001 Saturn SL, and 2001 Saturn SC2. However, it is still accessible from the selected car via links, so may be relevant.

DTC sets when PCM cam pulse has not been properly detected (cylinder No. 4 signal line not pulled to ground) for 136 engine revolutions when MAP sensor is greater than 30 kPa.

If PCM detects 20 correct cam pulses in a row, DTC will pass for remainder of ignition cycle.
