Code P1087 MINI Description

The P1087 MINI O2 Sensor Circuit Slow Response in Lean Control Range Bank 1 Sensor 1 code indicates that there is a problem with the oxygen sensor in the exhaust system of the vehicle. Specifically, it suggests that the oxygen sensor located before the catalytic converter on bank 1 (cylinder bank 1) is responding slowly in the lean control range. This means that the sensor is not providing accurate readings of the oxygen levels in the exhaust gases to the engine control module (ECM).
