Detection Condition

WARNING: This page is about a different car, the 2003 Mazda MPV and 2002 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

PCM monitors EVAP system leak detection pump load current while EVAP leak monitor is operating. If pump load current is more than specified while PCM obtains reference current value, DTC is set. This is an intermittent monitor. MIL is illuminated if PCM detects malfunction in 2 consecutive drive cycles.
