Mazda 3: a Obd-II code P2187

This answer was rated:

Have a Obd-II code P2187 on a Mazda 3 2006. What it means and what solutions can provide.
This code is indicative of a lean idle condition in your bank 1 o2 sensor stream. The most common cause of this is a bad purge solenoid valve. This is emissions related and can cause poor fuel economy and lead to other problems down the road. You should have the valve replaced and get the code cleared.
