Detection Condition

PCM monitors EVAP system leak detection pump load current (EVAP line pressure), while EVAP leak monitor is operating. If either of following malfunctions is detected 28 times or more successively, DTC is set.

• While obtaining reference current value, change in pump load exceeds specification.
• After obtaining reference current value, pump load current remains less than maximum pump load current for more than specified time.

This is an intermittent monitor. MIL is illuminated if PCM detects malfunction.
