What causes the Maxus V80 to suddenly stall while driving?
2 Answers
Reasons for the Maxus V80 suddenly stalling while driving: 1. Electrical circuit failure: Stalling due to low-voltage power interruption during driving. Check the ignition and starter switches, as well as the fuse box. 2. Electrical component failure: Usually caused by faults in the ignition coil, capacitor, or electronic ignition module. 3. Fuel system failure: Damaged fuel pump, ruptured fuel line, clogged fuel inlet, or empty fuel tank. 4. Sensor failure: Faults in the throttle position sensor, air flow sensor, intake pressure sensor, crankshaft position sensor, camshaft position sensor, etc. If sensors malfunction, stalling can occur. 5. Other failures: Engine timing system disorder, incorrect timing system calibration, engine valve issues, etc.
I've been driving diesel vehicles for over a decade, and this kind of sudden stalling is most likely fuel system related. If the fuel pump suddenly fails, or the diesel filter gets clogged like a sieve, the engine will just shut down like it's been starved. Those fuel injector wiring connectors can also be deadly if they get loose from constant vibration. Once when I was hauling cargo on the highway, the engine suddenly coughed twice and died - turned out the crankshaft position sensor was gummed up with oil sludge. Without this sensor's signal, the ECU directly cuts off fuel supply. Pay attention to whether there's any jerking before stalling - if the tachometer needle jumps erratically, it's almost certainly a sensor issue. Be extra careful with vehicles that have modified wiring - I've seen cases where improperly installed dashcams crashed the engine control module.
