What causes a Camry to suddenly stall?
3 Answers
The sudden stalling of a Camry may be caused by low-voltage power failure during driving. The relevant explanations are as follows: 1. Reasons for stalling: Excessive carbon deposits in the throttle body, idle speed motor, intake tract, intake valves, and combustion chamber may lead to sudden vehicle stalling. Carbon buildup roughens the inner walls of the intake pipes, creating vortices at these rough spots that affect air intake efficiency and fuel-air mixture quality, resulting in stalling. 2. Solution: Immediately turn on hazard warning lights, then grip the steering wheel and use intermittent braking (the brake system remains functional after engine stall - the first few brake applications will still work). After the vehicle comes to a complete stop, place warning triangles 200 meters behind the car.
My Camry also had this issue before, suddenly stalling on the road was quite a scare. Common causes usually involve fuel system problems, such as a faulty fuel pump or a clogged fuel filter, which prevents gasoline from reaching the engine, causing it to stop. It could also be an ignition system failure, like aged spark plugs or a malfunctioning ignition coil, leading to failure in ignition. Electrical issues, such as a dead battery or a faulty alternator, can also cause a power cut. Sensors, like a failing crankshaft position sensor, might mislead the computer into shutting down the engine. When stalling occurs, first turn on the hazard lights and pull over safely; don't force the car to keep moving. Check the malfunction indicator light. It's advisable to promptly visit a professional shop to inspect the fuel pump, wiring, battery, etc., and don't delay to avoid danger. Older Camry models often had fuel pump recalls, so check your vehicle's manual to confirm.
After driving for so many years, I believe sudden stalling in the Camry is mostly caused by electrical system issues. Aging batteries with unstable voltage can cause the engine to stop. Insufficient charging from the alternator is another major factor, especially when running the AC or headlights under heavy load. Blown fuses can interrupt critical circuits leading to stalling. Check that battery terminals aren't loose and ensure all connections are secure. Some vehicles experience similar problems due to short-circuited sensors. For prevention, regularly test battery life and avoid leaving the car undriven for too long with a depleted battery. Simply put, if the car stalls, try restarting it - if it works, get it repaired immediately; if not, wait for assistance. For safety, avoid long nighttime drives to prevent accidents.
