The crankshaft position sensor (also known as the crankshaft speed sensor) monitors engine RPM and assists the crankshaft to maintain proper timing and engine valve clearance. A faulty crankshaft position sensor can degrade idle quality, performance and engine efficiency; possibly causing damage to your internal engine components.

Step 1

Park the vehicle on level ground and engage the parking brake. Disconnect the negative battery cable for safety.

Step 2

Lift the vehicle using the floor jack. Locate the front jacking plate underneath the front of the vehicle, slightly to the right of the center. The plate is marked by an arrow. Place the jack stands on each side of the front, about 6 inches behind the front wheels. The side mounting parts are marked by an indentation along the bottom of the vehicle. Follow the same procedure to lift the rear.

Step 3

Use the socket wrench to remove the engine brush cover under the front of the engine. Remove the drive belt to make changing the sensor easier (optional).

Step 4

Remove the lower timing belt cover and the crankshaft pulley to access the crankshaft position sensor.

Step 5

Disconnect the electrical modules from the crankshaft position sensor, located next to the alternator. Take off the bolts with the socket wrench and remove the sensor.

Step 6

Place the new crankshaft position sensor in the exact location as the old one. Remount the bolts and connect the electrical modules. Reattach the crankshaft pulley and the lower timing belt cover. Put the drive belt back on if you removed it. Reattach the engine brush guard.

Step 7

Use the jack to lower the vehicle and remove the jack stands; starting with the rear. Reconnect the negative battery cable.

Well it is considered a B level repair. So to avoid running into any issues, I recommend setting up an appointment to have it installed by a trained auto mechanic.

Good luck with this : AnswerFor safety disconnect the battery, losen all drive belts,including alternator from the top screw if you reach it from the upper side with a 12 MM socket or wrench,then take off driver side front tire, remove two plastic pins from the engine splash guard with a 10 mm socket or wrench, get the splash guard down, now you support the engine with a hydraulic jack (I will recommend to use a piece of flat board of wood or plywood in between jack and engine) and put a jack stand on where removed tire, now take off Lower engine mount with a 14mm socket or 9/16, since we have supported the engine with a jack possible get off the upper left (driver side engine mount,so we will be able of moving up and down the engine since we will remove three screws of the bottom part of the timing belt cover, plus de AC idler pulley,but before that we also could start taking the belts off the crank shaft pulley,which is the pully where all three drive belts go to, this pulley there is only two ways to get it out since on Hondas they do come so thight, one is with the air gun, second is using a vice grip with a chain on the tip and thight it well and hold it very strong while some one tries to get it out with a very stron rachet and 3/4 socket or 19 mm. is recommended to use long extensions on the rachet, once you get the pulley out get the screws off the timing belt cover but just the lower part of the cover 3 10mm screws,plus remove the ac idler pully which is the small pulley on the midle of the lower part of the cover once you get the pulley out you get the cover out, and follow the cable that comes down by the oil pan and remove the screw of the golden angle that ends right on the left of the timing belt for and easy assambly of the new sensor is better to remove the other screw on the little angle of metal, just follow the same rod for the wire and that's it, connect it, put the cover back, install all drive belts in position and insert them on to the crank shaft pulley, and thight it good including belts, cover it back and you set the engine mounts back on set your tire back get the Jacks out plug your battery and done. Note : This is for a 1999 Honda Civic SI You really might want this done at a shop!!
