DTC P0300-P0304: Cylinder Or Multiple Cylinder Misfire: Notes
WARNING: This page is about a different car, the 2002 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
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. If DTC cannot be duplicated, proceed to TROUBLE SHOOTING - NO CODES
article for diagnosis by symptom.
When a misfire is detected on first trip that will damage the catalyst, MIL will flash and PCM will monitor misfire every 200 revolutions. If misfire frequency decreases to a level that will not damage the catalyst, MIL will change from flashing to illuminated. MIL will then illuminate every time ignition is turned on.
When a misfire is detected that will not damage the catalyst, MIL will illuminate on second trip and PCM will monitor misfire every 1000 revolutions.
