  1. Turn the ignition switch ON (II).
  1. Clear the DTC with the HDS.
  1. Start the engine.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0351, P0352, P0353 and/or P0354 indicated?
YES -
Go to Step 5 .
NO -
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ignition coil and the ECM.■
  1. Turn the ignition switch OFF.
  1. Exchange the ignition coil from the problem cylinder with one from another cylinder.
  1. Start the engine.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC indicated at the exchanged cylinder position?
YES -
NO -
Go to Step 9 .
  1. Turn the ignition switch OFF.
  1. Check the No. 14 IG (15 A) fuse in the under-hood fuse/relay box.
Is the fuse OK?
YES -
Go to Step 11 .
NO -
Go to Step 12 .
Is the ignition coil relay OK?
YES -
Go to Step 15 .
NO -
  1. Disconnect all ignition coil 3P connectors.
  1. Check for continuity between No. 1 ignition coil 3P connector terminal No. 3 and body ground.
Is there continuity?
YES -
Repair short in the wire between the ignition coils and the under-hood fuse/relay box. Also replace the No. 14 IG (15 A) fuse, then go to Step 25 .
NO -
  1. Reconnect the under-hood fuse/relay box 20P (white) connector.
  1. Disconnect the ignition coil 3P connector from the problem cylinder.
  1. Turn the ignition switch ON (II).
  1. Measure voltage between ignition coil 3P connector terminal No. 3 of the problem cylinder and body ground (see table).
