Crank position sensor...a problem?

go to junk yard. buy a 92-95 sensor. replace.....wait that requires you to take off the crank pulley bolt.... good fucking luck with that. I had to use a half inch impact gun to move that bitch. ummm if it pisses you off take to honda or phone a friend!!!!

i already know how to replace the CPS, i plain on doing it when i replace my noise as a son of bitch alternator...as for the crank pulley bolt...that's easy, impact to take off, tighten to 15 lbs with torque wrench, and one quarter turn via impact...(reading the service manual makes things easy )...just wondering if it completely goes out if it will keep me from being able to drive the car...but thank for the input ...

recently i have discovered that the computer is reading code:
P1336 - Crankshaft Speed Fluctuation Sensor Intermittant Interruption

the car runs fine, however. i currently am still driving the car daily and nothing is happining...after reading a bit the CPS is used for several things...the first is the tachomiter (which still works just fine BTW), and in some vehicles it is used for the ignition system...i would liek to know if the CPS is used for the ignition system or not...

You're confusing the crankshaft possition sensor (ckp) for the crankshaft speed fluctuation sensor. (ckf)

The ckf sensors only purpose is to help the ecu determine if there is a cylinder misfire. It shouldn't cause any type of running problem.

5th gen civics didn't come with a fluctuation sensor.

How to remove a crank pulley bolt at the junk yard:

2 Screw drivers
1 Impact
1 Air tank

1. Fill up your air tank.
2. Stick the one screw driver in the flywheel (if no tranny) or put two in the brake calipers (put the car in gear first)
3. Remove crank pulley bolt with impact

if you don't mind me asking where are the two sensors located? and which sensor is the code refering too? thanks for the input...

The ckf sensor is under the bottom of the lower timing belt cover. The ckp sensor is in the distributor. Code p1336 points to a problem with the ckf sensor/circuit.

Check the wires, sometimes they dont get put back in their holder after a timing belt install and get rubbed through by the alternator belt.

i'll be checking that, next thing is that the ckf is what is used for the tach right?

Nope, the tach is driven by the igniter.

bypass the ckf, give it a signal from the ckp, yes I'm a odb

go obd1.

^^eventually i will be going obdI, (and possibly turbo, looking at the rsmachine deal on the turbo kit was quit mind changing)...but for the mean time i will be running obd II...when i replace the alternator (bad bearings) i'll take a look at the wires and everything to make sure that they did not get spliced...if so i'll just do some handy electrical work and badabing badaboom, life is happy again...
