⚙️ Common Mack and Volvo ECM issues These ECMs (MP7, MP8, D12, and D13) often fail due to: 1️⃣ Injector faults — one or more injectors may fail at the same time. 2️⃣ ECM not communicating or powering on — the truck won’t start. 3️⃣ Barometric pressure sensor failure — this sensor is built inside the ECM. If your ECM shows any of these symptoms, we can repair it. ⚒️ 📩 Leave a comment or send me a message for help. #VolvoTrucks #DieselTech #ECMRepair | Oscar Truck ECM

If one injector fails but the injector and wiring check out, it’s likely your ECM. ⚠️Another red flag: 3 injectors failing at once. If wiring and injectors are fine, the ECM might be the cause.  Follow me for more ECM insights and diesel tech tips. #Trucks #DieselEngineRepair #TruckRepair | Oscar Truck ECM | Facebook
