The faulty sensor showed elevated readings before dropping sharply to 20 kPa [01:00], signaling a shorted sensor. Testing & Replacement [01:29]: Unplugging the faulty sensor caused the circuit to open (255 kPa max). Installing a new replacement sensor immediately restored the reading to a matching 101 kPa [01:40]. Road Test & Code Clearing [02:00]: Codes were cleared, and a road test confirmed normal engine performance and parameter operation [02:24]. Technical Breakdown [02:59]: The video explains why P0107 was the root cause: Because the MAP reading was stuck low at 20 kPa during operation, the Engine Control Module (ECM) could not correlate air input across the MAP, MAF, and Barometric sensors. To protect the engine, the computer set cascading range/performance codes (P2227, P2263, P0101) because it couldn't verify which sensor was telling the truth. Fixing the primary circuit code resolved all associated faults. #FordRanger #MazdaBT50 #P0107 #P2263 #P2227 #P0101 #MAPsensor #TurboDiesel #MechanicDIY www. deadtoaliveengines.co.nz #mechaniclife #Chevrolet #Ford #Holden #Kiwi #NZ #Waikato #Tirau #CambridgeNZ #autorepair #mechanic
