Notice

: * note for 2002 and later my vehicles: the readiness test can be completed in cold ambient conditions (less than 40f / 4.4 C) and/or at high altitudes (more than 7800 feet / 2400 m) if the drive pattern is repeated a second time after cycling the ignition off.

  1. Drive pattern
  1.  connect the obd ii scan tool to dlc3 to check monitor status and preconditions.
  2.  Release pressure in the fuel tank by removing and then reinstalling the fuel tank cap.
  3.  Start the engine and allow it to idle until ect becomes 167f (75 C) or greater.
  4.  Run the engine at 3,000 rpm for about 10 seconds.
  5.  Allow the engine to idle with the a/c on (to create slight load) for 15 to 50 minutes.

Notice

: if the vehicle is not equipped with a/c put a slight load on the engine by doing the following :
