A P04db crankcase ventilation system is a device that helps the engine cool down by providing air to the crankcase. A malfunctioning or disconnected P04db system can cause the engine to overheat, and can even cause a fire. If you think your car may have a disconnected P04db system, here are some steps to take:

  1. Remove the dashboard cover. The dashboard cover is held in place by four screws located at the front and two at the back. Use a Phillips head screwdriver to remove these screws.
  2. Locate the sensor behind the air cleaner housing on the passenger side of the engine block. This sensor is silver and shaped like a small hockey puck.
  3. If the sensor is not present, then your car most likely does not have a P04db crankcase ventilation system. If you do have a P04db system, then proceed to step 4 below.
  4. To test whether or not your car has a disconnected P04db system, start up your engine and apply pressure with your hand against the hood while it is running. If air bubbles come out of either side of the air cleaner housing, then your car most likely has a disconnected P04db system.
