Similar Conditions


If a "pending code" is set because of a Fuel System or Misfire Monitor detected fault, the vehicle must meet similar conditions for two consecutive trips before the code matures and the PCM activates the MIL and stores the code in memory. The meaning of similar conditions is important when you attempt to diagnose a fault detected by the Fuel System Monitor or Misfire Detection Monitor.

To achieve similar conditions, the vehicle must reach the following engine running conditions simultaneously (for the first failure recorded that set the code):

Engine speed must be within 375 rpm
Engine load must be within 10%
Engine warmup state must match the previous state (cold or warm)
Summary - Similar conditions are defined as conditions that match those recorded when the fault was detected and a code was set.
