Fig. Fig. 1: 3VZ-E Engine. Firing order-1-2-3-4-5-6. Distributor rotation: counterclockwise ,start by finding timing mark on crank shaft and rotate motor to timing indecater on motor ( to check if that is #1 at top dead center remove spark plug, piston should be at top of cylinder, use a soft object to feel piston come up you need 2 people to do this ,1 to turn motor over by hand and 1 to feel for piston rising now open dist. cap and note location of rotor pointing to #1 ignition wire or that will be now #1 and follow firing order ,if you go to auto zone and create an account (its free) you can get info on timing a motor and cylinder position .I REALLY hope this helped you .if it did let me know.thanks .
put the notch on crank pulley align with tdc (top dead center mark) on timing cover
Remove valve cover, firing order for a 4 cylinder engine 1342, piston 1 and 4 are up in same time,rocker arm on cylinder 1 intake and exhaust must have play, while on cylinder 4 must be in overlap both valves starting to open (partly depress),if no timing mark inser a screwdriver throught sparkplug opening turn gently to get the piston at tdc if so valve timing is ok without checking any mark,if you remove the cover you will see the mark at the right place
1 and 4, 3 and 2 are companion piston, you could do the same with 6 or 8 cylinders, you must know firing order
your question is realy garbled but I think you are asking about the timing of the cam and the crank sensors usually you have to have them both replaced at same time which means you can see the NO1 position on the cam and the position of the crank and thats with the cover off but I found out from another friend that if you go onto YouTube and request How To set timing on the Cam shaft and Crank shaft sensors you will get a video. MAKE SURE YOU SPELL IT ALL RIGHT OTHERWISE YOU WILL NOT FIND IT. Sorry about the Caps but wanted your attention use my spelling. Good Luck
The Cam sensor usually senses the position of the timing belt or timing chain gear and tells the computer when #1 cylinder is at top dead center. In other words, when #1 cylinder comes up. Crank sensor tells the computer when to fire the spark plugs in the rest of the cylinders. In other words, as the crank shaft goes around it tells the computer when each piston comes up so it can fire it's spark plug
STANDING IN FRONT OF CAR FACING THE CRANK SHAFT PULLEY, NUMBER 6 CYLINDER IS SECOND CYLINDER ON RIGHT ON DRIVER SIDE.LOOKING AT ENGINE FACING CAR.CYLINDERS FACING YOU ON PASSENGER SIDE IS 1 2 3 4 AND CYLINDERS FACING YOU ON DRIVER SIDE IS 5 6 7 8 FIRING ORDER IS 1 3 7 2 6 5 4 8
Your crankshaft turns 2x times the camshaft. Put it this way as # 1 cylinder reaches TDC (top dead center) of the firing/compression stroke, and this will be after a (8 degs BTDC) spark to ignite the air/fuel mix, the # 3 cyl. will be at BDC of the intake stroke and as #1 begins its power down stroke, (during explosion of air/fuel mix), #3 begins its compression up stroke, the #4 cyl. will be coming down with #1 cyl. but #4 will be in the beginning of its intake down stroke, and #2 cyl. will be coming up with #3 but #2will be in its BDC of the exhaust stroke. Which has just fired previously to #1. 1342134213421342 etc.
Now the cam turns to open / close the valves;
In the outline above, #1 cyl. valves will both be closed. #3 cyl. will have the intake starting to close at this point. #4 cyl. will just be starting to open its intake valve, and #2 will be starting to open its exhaust valve. Is all this clear as mud? So as the crank makes one full rotation (in a 4cyl. engine) only the firing of one cylinder has happened.and at every rotation one cyl. will fire. So #1 at TDC then one full rotation, #1 back at TDC, but this TDC is half of its 4 cycles, (1)Intake, (2)compression, (3)power, (4)exhaust. this 1234 refers to the 4 cycles of the rotation not firing order.
For a V engine format it would be where cylinder #1 is and that should be the furthest front combustion chamber. Once located where it is, that would be Bank 1 on that cylinder head. Bank 2 will be the opposite cylinder hear. With the exception of the Bugatti W16 engine which will have 4 banks due to having 2 Audi V8 cylinder heads side by side (giving the engine a W configuration) and use 16 cylinders for combustion.
The 2 crankshaft sensors are located on the front of the engine block, between cylinder Numbers 4 and 6. Crankshaft position A sensor is located on the upper crankcase and crankshaft position B sensor is located in the lower crankcase. Both sensors extend into the crankcase and are sealed into the engine block with O-rings. The crankshaft position sensors are not adjustable.
