Idk about the 99 civic but on my 95 jdm d15 the crank shaft position sensor is in the distributor. If the sensor is bad then you must replace the whole distributor. A bad wire could also cause this problem. Hope that helps good luck. jdmd15crx

The cps is tested with an ohmeter. Generally the sensor will read between 300-350 ohms. Also, check to see that the pick-up magnet is centered in the sensor housing. It should be positioned perpendicular to the flywheel teeth, with an air gap of 0.020-0.060 in. An adjustment to the high side, say 0.040-0.060 in. seems to work best. Also just a note, if the cps has failed, or is badly misadjusted, the engine will not run.
yes is should be done under the car or taking the manofold out???is is very hard to reach! It is on the driver side top of the bell housing. The wire wraps around the back of the engine and the plug is on the passenger side of the head.
The Crankshaft Position Sensor senses it's position from a toothed timing ring behind the Crankshaft pulley. The CKP is above and to the left of the crankshaft pulley.
in the distributor in the rear of the engine. sometimes known as a hall sensor
The Crankshaft sensor and the Cam sensor monitor the position and or the speed of rotation of the crankshaft. Together they send signals to the ECM. The ECM uses that information along with info from other sensors to send spark and fuel to the cylinders at the correct time. Some engines only have only a crank sensor to perform that job. Other engines that have both crank and cam sensors that split the duties.
Crankshaft position sensor circuit malfunction.
Yes it can. The crankshaft position sensor is one of the major sensors for spark timing.
