I REPLACED MY CAMSHAFT SECOR ON MY 2002 FORD WINDSTAR BUT IT WONT TURN OVER DO I NEED TO BUY ANOTHER ONE .
If you simply pulled out the old camshaft synchronizer and put it back in or pulled off the synchronizer, replaced the senor and put the assembly back into the engine, you did not perform the service correctly and the ignition timing is now incorrect. There is a procedure that needs to be done in a specific order including having the engine in the proper position in order to install the part in the proper timing. Consider hring an experienced technician like one from YourMechanic who can come out and correct the installation to correct your no start situation.
How to Identify and Fix Common car Problems ?

The most common failure is the crankshaft position sensor. These fail much more frequently than the cam sensor and will cause a no start. It can also occur if the timing belt broke or jumped a tooth. I would do a compression test also to see if there is low compression.
Unfortunately, there`s no way to reset a camshaft position sensor. If you`re having camshaft issues (check engine light on, acceleration trouble, sputtering and stalling, etc.), you`ll have to replace the part entirely.
After you`ve replaced the camshaft sensor, be sure to take your car to a qualified mechanic and ask them to reprogram it using a OBD-II scanner. Doing so will clear any error codes and make sure that the engine computer is getting accurate signals from the new sensor.
While the new sensor is now installed, and you may get lucky and have it function perfectly right from the start, it`s highly recommended to “relearn” the sensor at this point in order to calibrate the entire system properly.
Evidently, you cannot reset a camshaft position sensor. Therefore, you will need to replace the component if your camshaft malfunctions (check engine light on, acceleration issues, sputtering and stalling, etc.).
NOT PERFORMING A RELEARN PROCESS
In rare cases the engine may misfire or go into “reduced power” or “limp mode” especially under high RPM/load situations Additionally, omission of the relearn process could cause the vehicle to be unable to pass an emissions test due to incomplete or failed misfire monitor.
Reasons for failure of the camshaft sensor can be: Mechanical damage. Break in the encoder wheel. Internal short circuits.
Once you install your new camshaft, you may need to go through a break-in procedure, depending on what the manufacturer recommends. This can be quite an extensive job for some vehicles – and if you do it incorrectly, engine damage can occur.
Error code P0340 indicates a malfunction with the camshaft position sensor A circuit. This type of malfunction can cause serious issues that require immediate repair because the underlying cause of the code could damage your vehicle`s engine if you continue to drive it.
You don`t need to reset it, once the engine turns over it will send the information to the ECM and the ECM will be ready to start the engine.
OBD2 Diagnostic Trouble Code P0340 indicates that the Camshaft Position Sensor `A` Circuit Malfunction in Bank 1 has been detected. The camshaft position sensor (CMP sensor) provides information regarding the rotational speed of the camshaft and where the camshaft is positioned in relationship to the crankshaft.
This can cost anywhere from $200 to $400.
If the sensor is awry it will send the wrong information into your car`s on-board computer, resulting in the inability of your engine operating system to sync the engine pistons together. This causes poor acceleration and makes your car fail to maintain constant speed.
The camshaft sensor enables the engine control to determine the exact position of the crankshaft drive. This information is required to calculate the ignition point and injection point, among other things.
Autel TS601 TPMS scan tool integrate tire pressure sensor Diagnostics(Check), Activation(Read), Programming, and Relearn in one.
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
Dead car battery: A dead battery is the most common reason why a car won`t start. If you have a battery tester, check your battery to see if it`s weak. If you don`t have one, try to jump start your car with jumper cables.
Slowly accelerate the engine to 4,000 rpm (or indicated rpm for your vehicle). Hold rpm until the engine speed drops back toward idle. Release the throttle immediately once procedure is learned! Once the variation values are learned, the ECC will return engine control to the driver.
If your vehicle idles roughly, stalls frequently, has a drop in engine power, stumbles frequently, has reduced gas mileage, or accelerates slowly, these are all signs your camshaft position sensor could be failing.
Your vehicle should be equipped with four different camshaft position sensors, one for each of the engine`s camshafts. They are mounted in the front of the cylinder heads, near the camshaft actuators, across from each other.
Car Will Not Start: Over time, as the camshaft position sensor fails, the signal it sends to the engine control module weakens. When the engine no longer receives the signal, you will not be able to start your car.
The camshaft is usually driven either directly, via a toothed rubber “timing belt”` or via a steel roller “timing chain”. Gears have also occasionally been used to drive the camshaft. In some designs the camshaft also drives the distributor, oil pump, fuel pump and occasionally the power steering pump.
Low battery voltage can contribute to a MIL On condition for P0335 (Crankshaft Position Sensor Circuit) and/or P0340 (Camshaft Position Sensor Circuit) due to inconsistent rotational speed of the engine`s crankshaft.
Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits.
