Engine failure can be caused by malfunctions in the fuel supply system, ignition system, intake system, exhaust system, and various sensor components. A faulty oxygen sensor near the three-way catalytic converter can also trigger engine failure. Vehicle owners can use the elimination method to troubleshoot each component individually. If the engine warning light comes on while driving, it is advisable to visit a repair shop to check the fault codes. In automotive design, to ensure the engine operates in good condition and maintains its normal working lifespan, oxygen sensors are installed to monitor the engine's combustion status. Poor combustion conditions can lead to excessive engine wear, resulting in the illumination of the engine warning light.

Why can't the Accord key turn and the car won't start?

The reasons why the Accord key can't turn and the car won't start include the steering wheel being locked, incorrect gear position, or vehicle malfunction. Steering wheel locked: If the steering wheel can't turn and the key can't twist, it's due to the vehicle's simple anti-theft feature being at the intersection of key unlocking and lock cylinder torque. Simply turn the steering wheel lightly clockwise (or counterclockwise) while gently twisting the key to unlock it smoothly. When parking, try to straighten the steering wheel before turning off the engine and removing the key. Incorrect gear position: For automatic transmission vehicles, the gear must be in the "P" position to start the car. Develop a good habit of placing the gear in "P" before turning off the engine. Always check the gear position before starting. Vehicle malfunction: If the car still won't start in "P" position, or if the dashboard shows an abnormal gear indication, it's recommended to seek timely repairs. This could indicate a damaged electronic gear sensor or electro-pneumatic valve, which should be inspected and repaired promptly.
