About TDC Sensors

The Peugeot TDC sensor (Top Dead Centre sensor) is an important and clever electronic sensor which works in conjunction with the car's ECU, playing a crucial part in enabling the engine to run on time and smoothly. Information gathered by the TDC sensor is sent to the ECU which uses it, along with information from other engine sensors, to determine and control the ignition and fuel injection timing of the engine, transmission changing and variable valve timing. 

The TDC sensor can be found in the engine compartment, positioned on the gear box above the fly wheel, or mounted on the top of the transmission bellhousing at the left-hand end of the cylinder block. It can be easily seen when the air box is removed. 

It is common for an internal combustion engine to use a four-stroke action.  The intake stroke, which is the first stroke of the pistons, draws an equal amount of air from the inlet manifold into each cylinder, delivering the air via the air intake valve. For the next three strokes of the engine the air intake valves are shut while compression, combustion and exhaust processes are occurring. Then the intake valves open again and once more the air is drawn through into the cylinders from the inlet manifold. The spark plugs should fire, igniting the fuel in the cylinder, when the piston is at top dead centre. When the piston is in this position, the air intake valves are shut while compression, combustion and exhaust processes are occurring. The TDC sensor lets the ECU know when a cylinder is at top dead centre and the ECU then instructs a spark to be sent to the correct cylinder at the correct time for ignition to occur. The spark is produced via the spark plug which provides an electrical current to the combustion chamber in a cylinder in a petrol engine. The spark produced ignites the engine enabling the air/fuel mix to burn in the cylinder and combustion to occur. A defective TDC sensor can literally stop the engine from starting. If the engine does start, a fault with this sensor may cause the engine to run poorly. 

As is often the case with electrical components, the TDC sensor can fail because of damage caused by corrosion or it can simply wear out. A faulty TDC sensor may cause the engine control unit to miss a correctly timed signal and the spark may not ignite in the right cylinder at the right time, which could lead to the engine operating badly or ceasing to work. Correct operation of the TDC sensor is vital to the running and timing of the engine. It is wise to consult with your mechanic when experiencing problems with ignition and the engine, to ensure the correct fault is found and fixed as soon as possible. When this electronic sensor goes wrong, it is important install a compatible replacement part. The Peugeot TDC sensor offers complete compatibility, specifically manufactured for the make and model of your vehicle.

Peugeot trivia

  • Peugeot might not be a name in Formula 1 (they did try a few times, but it never quite worked out), but they have been dominant in other races. In particular, four victories in an incredible 24 hours at Le Mans, and six impressive wins in the Dakar rally, to name just a few.
  • 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.
  • You know the name Ettore Bugatti and the brand that bears his name, but did you know that Bugatti also designed the four-cylinder engine in 1912 for the Peugeot Bébé? You can't miss that unmistakable Bugatti look once you know that fact, and the car quickly became France's best selling car.
  • Peugeots, especially the 504, are incredibly popular in Africa and have been affectionately called Africa's workhorse. The 504 is a model that seems particularly well-suited to the rough terrains of Kenya and Ghana.
  • It was Armand Peugeot who turned the company into car manufacturing. He called the company the Société des Automobiles Peugeot (Peugeot Automotive Society) and was the one who approved the famous lion emblem that is still used today.
