Where is the tdc sensor of Honda Accord?

Honda Accord tdc sensor is a cam position sensor behind the engine valve cover.

The top dead center position sensor is an electromagnetic induction sensor. When the top dead center sensor fails, it may lead to engine jitter, and the car will not have high speed when driving. The reasons for this situation are dirty throttle, stuck throttle or improper adjustment, or low fuel pressure, blocked injector, improper ignition timing, weak high-voltage spark or low engine cylinder pressure.

After the engine fails, it needs to be checked one by one. If the accelerator is dirty, it needs to be cleaned with carburetor cleaner. If the spark plug is used for a long time, it will lead to the aging of the spark plug and may lead to poor ignition. If this is the case, please replace the spark plug as soon as possible.

When the engine is idling, the speed is reduced from 850 rpm to 800 rpm. At this time, when the accelerator pedal of the car is stepped down and the engine speed is kept at 3000rpm, the engine is still shaking violently and the engine fault light is on. In this case, the tdc sensor waveform should be read by the detector. If the displayed waveform pulse signal tends to be flat and the signal is abnormal, replace the top dead center sensor in time.
