How do you calculate TDC on an exhaust stroke?
How do you calculate TDC on an exhaust stroke?
Mark your balancer with a marker, and then slowly rotate the crankshaft by hand in the opposite direction; until you come up against the stop again. Mark your balancer again. Measure the distance between the two marks and divide by two. As a result, This is your (TDC).
What are the symptoms of a bad TDC sensor?
Another common symptom of a bad or worn out TDC sensor is when the car seems to run rough or the engine misfires. If the TDC sensor is not working properly, the motor usually will shut off quickly to avoid damage to internal components.
When to set the engine to TDC on the exhaust stroke?
NOTE When setting the engine to TDC on the compression stroke for cylinder #1, you must realize that the crankshaft rotates twice for every single rotation of the camshaft. So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.
When did the 3.0L camshaft position sensor change?
Do not get this confused with a CPS which is a Crankshaft Position Sensor) Starting in 1995, the 3.0L received a distributorless ignition system (DIS).
How can I tell if my engine is at TDC?
So, after you get the crankshaft (by flywheel indication or by checking actual piston location), check the camshaft sprocket to make sure the camshaft alignment mark is at the TDC position as well. This procedure can be performed by one person. However, it is much easier to perform with two people.

How much does a bad camshaft sensor cost?
In this case, because of an inaccurate reading from a bad camshaft position sensor, more fuel than necessary is injected into the engine which causes your fuel economy to drop. To replace a camshaft position sensor, you can expect to pay anywhere from $120 to $300. Parts alone will run about $50 to $200.
Where is the sensor located on a camshaft?
Install the camshaft sensor housing so that the drive gear engagement occurs when the arrow on the locator tool is pointed approximately 30°counterclockwise (the sensor terminal connector should be aligned with its matchmarks) from the face of the cylinder block.
How does a camshaft position sensor work on a Vauxhall Ecotec?
When a slot in the camshaft passes the coil as the camshaft rotates, the slot inductance of the coil changes, which produces a an AC current that serves to indicate the position of cylinder #1 relative to TDC. This type of CMP sensor is commonly used on Opel/Vauxhall ECOTEC engines.
