Detection Condition

WARNING: This page is about a different car, the 2003 Mazda Protege5 and 2003 Mazda Protege. However, it is still accessible from the selected car via links, so may be relevant.

PCM monitors input voltages from purge solenoid valve. If voltage at PCM terminal 67 remains low or high, PCM determines purge solenoid valve circuit has malfunction. This is a diagnostic support DTC (monitored once per key cycle). MIL does not illuminate. Freeze frame data is not available. DTC is not stored in PCM memory.
