Ford 3R2Z-6A257-DA Camshaft Position Sensor

Disconnect the negative battery cable from the battery and position the number one piston several degrees before TDC on the compression stroke. Remove the right valve cover and attach a dial indicator to the cylinder head with the plunger inline with and resting on the pushrod side of the rocker arm. Remove the timing chain cover and temporarily remove the timing chain and sprockets to access the chain tensioner. Temporarily install the timing chain and sprockets without the tensioner, then slip the timing chain cover and vibration damper in place to provide timing marks. Turn the crankshaft clockwise until the number one piston is at TDC to take up the slack on the right side of the chain, then zero the dial indicator. Slowly turn the crankshaft counterclockwise until the slightest movement is seen on the dial indicator, noting how far the number one piston has moved away from TDC by looking at the ignition timing marks; if the mark has moved more than 6 degrees, install a new timing chain and sprockets. Position the number one piston at TDC on the compression stroke and remove the timing chain cover, avoiding turning the crankshaft during vibration damper removal. Ensure the crankshaft, camshaft, and balance shaft sprocket timing marks are aligned; if not, use the vibration damper bolt to turn the crankshaft clockwise until all marks are aligned. Remove the camshaft sprocket mounting bolt and camshaft position sensor drive gear without turning the engine, taking care not to allow the crankshaft to turn from TDC. Compress the timing chain tensioner with a screwdriver and insert a drill or Allen wrench as a retaining pin to hold it in the retracted position, then pull the camshaft sprocket/chain off the camshaft. If intending to remove the tensioner assembly, remove the two bolts holding it to the block. Turn the crankshaft until the key is facing up, drape the chain over the camshaft sprocket, and turn the sprocket until the timing mark faces down, ensuring the chain is positioned over the camshaft and crankshaft sprockets with their timing marks aligned before slipping both sprockets onto the camshaft and crankshaft. When correctly installed, a straight line should pass through the center of the balance shaft gear, the camshaft, the camshaft timing mark, the crankshaft timing mark, and the center of the crankshaft; do not proceed until the valve timing is correct. Install the camshaft position sensor drive gear, aligning the keyway with the Woodruff key on the camshaft, then apply a non-hardening thread locking compound to the threads and install the camshaft sprocket bolt, tightening it to the specified torque. Finally, remove the retaining pin from the timing chain tensioner and reinstall the remaining parts in the reverse order of removal.

Disconnect the cable from the negative battery terminal and position the number one piston several degrees before TDC on the compression stroke. Remove the right valve cover, loosen the number one cylinder rocker arms, and turn them out of the way, then attach a dial indicator to the cylinder head with the plunger in-line with and resting on the pushrod, using a short length of vacuum hose if necessary to prevent slipping. Remove the timing chain cover and temporarily remove the timing chain and sprockets to access the chain tensioner. Temporarily install the timing chain and sprockets without the tensioner, then slip the timing chain cover and vibration damper in place to provide timing marks. Turn the crankshaft clockwise until the number one piston is at TDC to take up the slack on the right side of the chain, then zero the dial indicator. Slowly turn the crankshaft counterclockwise until the slightest movement is seen on the dial indicator, stopping to note how far the number one piston has moved away from TDC by looking at the ignition timing marks; if the mark has moved more than 6 degrees, install a new timing chain and sprockets. Position the number one piston at TDC on the compression stroke again, remove the timing chain cover while avoiding turning the crankshaft during vibration damper removal, and ensure the crankshaft, camshaft, and balance shaft sprocket timing marks are aligned. If they aren't aligned, use the vibration damper bolt to turn the crankshaft clockwise until all marks are aligned. Remove the camshaft sprocket mounting bolt and camshaft position sensor drive gear without turning the engine, taking care not to allow the crankshaft to turn from TDC. Compress the timing chain tensioner with a screwdriver and insert a drill bit, punch, or Allen wrench as a retaining pin to hold it in the retracted position, then pull the camshaft sprocket chain off the camshaft. If intending to remove the tensioner assembly, remove the two bolts holding it to the block. Turn the crankshaft until the key is facing up, drape the chain over the camshaft sprocket, and turn the sprocket until the timing mark faces down. Position the chain over the camshaft and crankshaft sprockets with their timing marks aligned, then slip both sprockets onto the camshaft and crankshaft. When correctly installed, a straight line should pass through the center of the balance shaft gear, the camshaft, the camshaft timing mark, the crankshaft timing mark, and the center of the crankshaft. Install the camshaft position sensor drive gear, aligning the keyway with the Woodruff key on the camshaft. Apply a non-hardening thread locking compound to the threads and install the camshaft sprocket bolt, tightening it to the specified torque. Finally, remove the retaining pin from the timing chain tensioner and reinstall the remaining parts in the reverse order of removal.

These engines, are challenging to work with and need tools that are unique to this type of engine. During any activity involving the timing chains, special precautions should be taken because careless disassembly will result in impact on the engine. Because this is an interference engine design, a failed timing chain will likelihood affect the valves and likely, the piston of the said cylinders which will require the cylinder heads to be pulled. The timing system is delicate, and if not set right, it may lead to terrible destruction of the engine; as such, this type of repair is best undertaken by experienced mechanics, and, if there is any doubt at all, it is advisable to consult with an expert. Check all work before starting the engine, then check it again. For the procedure, two special camshaft holding tools are needed in order to grip the camshaft. Starting up, remove the battery cable, the valve cover, the timing chain cover among others. Replace the crankshaft sprocket bolt and set the engine at TDC for cylinder number 1 using the fact that this position will be roughly TDC at this stage. Rotate the engine clockwise until marks on each intake camshaft VCT unit are aligned with degrees, those with cylinder heads. Take out the bolts that hold the valve train oil tubes and with these, put the special camshaft locking tools. If the timing marks on the part of the timing chain are not prominent or visible, one is supposed to create paint dot. Umber the main timing chain tensioner and the lower chain guides and the bolts that fix the VCT solenoids should be removed while taken in poly bags labeled according to their position. Discharge the first timing chain, as well as the upper chain idlers. The camshafts are operated by a second chain of timing and in order to access three units at the top of the engine known as the VCTs, the tensioner of the timing chain must be locked. If replacement of the primary timing chain sprocket is intended, it is necessary to remove the bolts fixing the channel plate. For installation, the areas where the sprocket and plate are to be fitted should be cleaned so that there is tight connection; if the gasket has been removed then a new one is fitted. Timing chain tensioners shall be replaced with new ones, if the old ones have been removed and the engine type is a secondary timing chain. The unit is positioned correctly when a snap is felt and the tensioner shoe is then set into the place. Position the colored links of the secondary timing chain against the marks noted on the VCT units and fit the chain, making certain that the VCT units locate with the dowel pins on the camshafts. New bolts for the VCT units; torque to the following value: Like the secondary chains or VCT units, place the primary timing chains by lining up the coloured links with the marks on the sprockets. After all the components are installed they have to be aligned, release the pins which hold the primary chain tensioners back, the other parts need to be put back in the reverse manner. Slowly spin the crankshaft counterclockwise manually through not less than three full cycles and should some amount of friction be encountered on any of the cylinders, the spinning must stop so that faults might be assessed. Last but not the least replace the old oil filter, refill the engine oil and coolant and take the vehicle for the road test to check for oil leakage.
