DTC P1320: Ignition Signal: Notes

NOTE: If DTC P0340, P0335, P1335 or P1336 are also displayed, perform diagnosis for DTC P0340, P0335, P1335 or P1336 first.
NOTE: Using the following diagnostic procedure assumes the presence of a current (hard) DTC or the ability to duplicate the setting of the DTC using DTC confirmation test(s), intermittent recreation procedures or a test drive under conditions stored in freeze frame data. See TESTING PROCEDURE under SELF-DIAGNOSTIC SYSTEM in SELF-DIAGNOSTICS - INTRODUCTION article. If DTC cannot be duplicated, proceed to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom.
