⚙️ 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

Ever wonder what that small tube on your Volvo D13 or Mack MP8 is actually doing? That’s the Venturi Tube — the part responsible for measuring EGR flow using a pressure drop so the ECM knows exactly how much exhaust gas is being recirculated. When it clogs or leaks, you get bad readings, poor performance, and derates.Raw clip explains it all.TAT Express4140 Langdon Rd, Dallas TX 75241972-225-3017Google link: https://maps.app.goo.gl/KzW9PgYB8Vr7Vw8x7?g_st=ipcFull video: https://youtu.be/roRAA_ZTa

🚛 Do you drive a Volvo with D12, D13 or a Mack with MP7, MP8? A common issue we’re seeing is with these the ECMs are injector drivers. 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
