What Causes the Peugeot 408 to Stall Automatically?
2 Answers
Peugeot 408 stalling automatically may be due to a fuel pump failure preventing fuel supply, lack of high-voltage spark, or faults in the driving computer or body module. Below are the specific details of the Peugeot 408: 1. Vehicle Positioning: The Peugeot 408 is a compact car launched by Dongfeng Peugeot, with dimensions of 4750/1820/1488mm and a wheelbase of 2730mm. 2. Powertrain: Equipped with a 1.6T engine, the maximum power output is 125kW, with a peak torque of 250N·m, paired with either a 5MT or 4AT transmission. 3. Safety Features: The Peugeot 408 features a unique 6+X safety system, which includes EVA emergency braking assistance, Bosch 8.1 version ABS anti-lock braking system, EBD electronic brake-force distribution, TSC traction control, and ESP electronic stability program.
As a veteran driver with over a decade of experience behind the wheel of a Peugeot 408, I've encountered several instances of unexpected engine stalling. The most common culprit is ignition system failures - aging spark plugs or faulty ignition coils often cause the engine to die immediately after starting, particularly noticeable during cold starts. Another frequent issue stems from severe carbon buildup in the fuel system, where clogged fuel injectors disrupt proper fuel delivery, creating air-fuel mixture imbalances that lead to stalling during frequent deceleration in traffic congestion. Electrical faults also pose problems - unstable alternator output, corroded battery terminals causing power shortages, or failed sensors like the crankshaft position sensor can all trigger sudden engine shutdowns. The safety risks are substantial; I once narrowly avoided a rear-end collision after stalling on the highway, which was ultimately resolved by replacing a sensor. My advice: regularly clean the throttle body, inspect spark plugs, and address issues proactively rather than waiting for accidents to occur.
