Which outcome occurs when a diesel engine's common rail pressure sensor fails high during operation?

💡 Explanation

When a common rail pressure sensor fails high, the engine control unit (ECU) interprets a higher-than-actual fuel pressure because faulty signal, prematurely advancing the fuel injection timing, leading to pre-ignition. Therefore, engine knock occurs, rather than black smoke, converter damage, or misfire, which stem from distinct sensor or mechanical failures.
