Where each cylinder is

CylinderMisfire codeLocationPlace in firing order

Bank 1 is always the bank that contains cylinder 1, so for this engine bank 1 is the rear bank with cylinders 1-2-3; bank 2 is the front bank with cylinders 4-5-6. Oxygen-sensor, camshaft and catalyst codes that name bank 1 or bank 2 use the same split.

How to find a cylinder on this engine

  1. Find the front of the engine: the end with the drive belt and pulleys.
  2. Find bank 1, the rear bank that holds cylinder 1. On this engine it is the rear bank.
  3. Count from the belt end. Cylinders 1-2-3 run along bank 1 and 4-5-6 along bank 2, each starting at the belt end.
  4. Match the code: P0301 is cylinder 1, P0302 cylinder 2, and so on. P0300 means a random or multiple misfire and does not name a cylinder.
