About TDC Sensors
The Jaguar 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 Jaguar TDC sensor offers complete compatibility, specifically manufactured for the make and model of your vehicle.
- The Jaguar XJ has that luxurious leather interior, but did you know that all of that leather comes very specifically from Scottish Angus Bulls? Bulls don't get stretch marks, and they don't get bitten much by mosquitoes either. Belly and neck skin becomes the dash and door finish, while the backbone and the rump are used for the seats.
- Talk about testing your car! Jaguars are put through a very rigorous climate test, where they are first tested in -40 degrees for twelve hours. Once that's done, the cars are then sprayed with water while standing in a 0-degree wind tunnel. That's why they cope so well with British weather.
- PM Margaret Thatcher was determined to keep Jaguar as a British company, and in 1984 she announced that the brand was protected from foreign purchasing. The government retained a 50% share of the company until it became clear that foreign investment was essential as 1990 rolled around.
- The 2014 Superbowl advert for Jaguar featured Brit actors Ben Kingsley and Mark Strong, with a terrified Tom Hiddlestone hanging out of a helicopter as it flew across London. Not many people know that the driver used for this advert was The Stig (Ben Collins).
- To show off just how light the F-Pace SUV was, Jaguar built a loop and the SUV not only tackled it but completed the loop on its first go. The feat earned Jaguar a place in the Guinness Book of World Records.
