Fault code P 1 12E

1. Fault code applicable vehicle type: mini fault code: P 1 12E. English meaning: intake manifold pressure/throttle angle-signal correlation, low English meaning: intake manifold pressure/throttle angle-signal correlation, low category: powertrain system (manufacturer's own meaning) Detailed meaning: 2. Fault code applicable model: BMW fault code: P 1 12E Chinese meaning: manifold absolute pressure (MAP) sensor-throttle opening is too low English meaning: MAP sensor-throttle opening is too low Category: powertrain system (manufacturer's own meaning) Detailed meaning: manifold absolute pressure (MAP) sensor is used to measure the intake manifold. Then the powertrain control module (PCM) will determine the basic fuel injection quantity of the injector according to the difference between the intake manifold pressure and the atmospheric pressure (which is linearly related to the engine load), thus helping the engine to achieve the best air-fuel ratio under different working conditions.
