What is another name for a TDC sensor?
Top Dead Center
This is known as Top Dead Center (TDC) and in today’s modern engines is monitored by a top dead center sensor. TDC is often defined as when the first cylinder to fire (usually number one cylinder) has the intake and exhaust valves both closed at the same time.
What does TDC sensor no pulse mean-JustAnswer?
At intervals the dashboard sign “Check Engine” lights up. It goes off when I switch of the engine and restart again. I had it diagnosed with an electronic diagnostic tool. The print-out show the following result:CODE002:8-1 TDC SENSOR (1) NO PULSEQuestion what do these codes mean and what do I need to do to sort out the problem.
How does a TDC sensor work in a diesel engine?
The optimum time for the spark plug to fire is usually just before the piston reaches TDC, so the TDC sensor sends an impulse to the engine control unit to ensure that ignition is correctly timed. A similar principle applies to diesels, but as there is no spark plug the TDC sensor contr…
What causes a bad top dead center ( TDC ) sensor?
However, since the sensor is an electrical part, it can fail. Issues such as wear and tear, cracking, and even corrosion can take over and cause a malfunction of the TDC sensor. If a problem exists with this sensor, certain warning signs will alert the driver to a potential problem.
What does TDC mean on a harmonic balancer?
In older engines, TDC was marked on a harmonic balancer as zero degrees and allowed a mechanic to assemble an engine and adjust cylinder head valves to ensure smooth operation. Today’s engines are assembled with the same precision, however, the TDC sensor continually monitors the firing sequence of all cylinders.

How long does a TDC sensor last in a car?
This sensor is vital as today’s modern ignition systems are frequently adjusted to variable driving conditions. When everything works as planned, the TDC sensor should last forever. However, since the sensor is an electrical part, it can fail.
