About Engine Knock Sensors

Timing and temperature are crucial in a vehicle's ignition system in order for combustion to occur correctly and for the engine to perform at its best. In an engine, when fuel is not ignited properly/at the right time it produces an explosion that can ruin the finely-tuned cycle of the engine, and can lead to damaged engine components. These little explosions are referred to as engine knock or detonation, and produce a knocking or pinging sound in the engine. The Peugeot engine knock sensor functions to detect harmful engine vibrations caused by engine knock and this information is used to determine ignition timing and prevent further detonation.

Positioned on the intake manifold, engine block or cylinder head, the engine knock sensor works by sending a signal to the car's ECU (Electronic Control Unit) which will use this information to adjust the ignition timing to protect the engine from what is known as pre-ignition; the fuel combusting and burning before it is ignited by the spark plug. 

If the fuel burns in the engine before it should, usually due to the engine's compression being too low, this can lead to a build-up of carbon deposit and debris. When these deposits accumulate in the cylinder head, the air and fuel mixture does not have enough space, leading to compression being too high in the cylinders, which results in engine knock. The engine-knock-sensor functions to detect when this is happening and with the help of the ECU avoid this pre-ignition.

If there is a problem with the engine knock sensor the warning light should illuminate on the dashboard of the car. Signs of a malfunctioning engine knock sensor can include a loss of acceleration and the vehicle not achieving as many miles to the gallon as usual.  It's advisable to seek advice from a mechanic to establish the exact cause of the fault. When you need to replace this part, the Peugeot engine knock sensor is the ideal choice, designed to be compatible with the make and model of your vehicle. 

Peugeot trivia

  • The first diesel engine prototype from Peugeot was built in the 1930s, but they didn't start releasing models commercially until 1959 (the 403).
  • It was also in 1913 (some might say because of the Indy 500 win) that Peugeot were responsible for the production of half of all of the cars in France. That quickly made them one of the world's biggest names in the automotive industry.
  • It's hard to believe, but the Peugeot company was founded in 1810! Of course, it didn't make cars then. Instead, it built pepper mills, salt mills and, eventually bicycles. It wasn't until 1889 that the first Peugeot car was made (they only made four of them, and they were powered by steam).
  • All models of Peugeot have a number designation with a 0 in the middle. There's a persistent myth that this is because the designers wanted to integrate the starting handle, and chose the central 0 as the ideal way to hide the slot. There's no substance to that myth, but those numbers are an indication of the size and age of the car.
  • Peugeots have been seen on the big and small screen. Most notable, the Peugeot 403 convertible was the car of everyone's famous scruffy detective Colombo. There was also an episode of Absolutely Fabulous where Edina and Patsy drive through France in a 205.
