Possible causes – Faulty Manifold Absolute Pressure (MAP) sensor– Manifold Absolute Pressure (MAP) sensor harness is open or shorted– Manifold Absolute Pressure (MAP) sensor circuit poor electrical connection When is the obd code mean? If the Powertrain Control Module (PCM) detects a Manifold Absolute Pressure (MAP) sensor signal voltage that is intermittently low, the P1107…
