how to remove crank sensor in car

[98mitsubishigst]

I figured out that my ecu is not bad, its throwing a code for the crank sensor..

Now my motor is in the car and im not getting spark or fuel; i've also noticed people have had this problem before me..

Now; i bought a brand new crank sensor and its throwing this code..
What could it be that its not working? Also is there a VFAQ on how to remove the crank sensor in car?

your talking about how to remove the crank sensor on the engine down by the crank right? if so your ganna have to take off your crank pulley and your timing covers, you might have to take off the timing belt but im not sure. there are 2 bolts holding it in place, should be pretty easy to replace.

i would check the wiring first. if the wiring to the sensor is bad like ive seen so many times you will save yourself having to change the sensor.. just check the wire before you do all the work.

does anyone have a picture of the crank sprocket, the sensor and i believe there is a metal plate that spins around with the crank sprocket. i just need a picture of the order that the crank sprocket area gets put back together. or if someone can tell me the order to put the crank areatogether (sprocket, crank sensor, the metal plate and anything else in that area together)

Heres a little write up a made for replacing the CPS on my 99 gsx

I went through a period where I couldnt get no spark on my GSX....I swapped Coil Packs...Transistor packs...ECU's....CAS's....still a no start....Put a new CPS...(Crank Position Sensor)in voila fired right up....

In order to change out the CPS...its a tad more involving but nothing completely complicated..

1st, Disconnect Battery Negative, you should have some ratchet wrenchs handy...they are a life saver in areas like this...I'll us the acronym RW for them in the later lines...Pull off driver side tire and prop car up on jackstands...

2nd, put a 3/4 inch socket on a 1/2 inch drive ratchet and put it on the crank bolt...and get a 10mm socket and unbolt the a/c line on top of the driverside motor mount(you know the big one right there in the way ...just move it to the otherside of the timing cover it'll stretch and bend a bit...

3rd, use 10 mm RW on 1 or 2 bolts on the water pump pulley(can probably get to 2 at a time)and loosen them.

4th, turn motor slightly with the 1/2 drive with 3/4 inch socket some on the crank bolt

5th, loosen other 2 bolts on water pump with RW

6th, now loosen and take off the 4 12mm bolts holding on the harmonic balancer...use the 1/2 inch drive as leverage and DO NOT let it rotate counter-clockwise...Remove balancer

7th, loosen the power steering pump and alternator and A/C (if applicable) to allow slack on the belts...

8th, Remove driver side motor mount (optional but very very highly recommended)
Put jack with a piece of wood under the motor and jack it up to relieve some weight off the mount...
2 17mm nuts and 1 14mm bolt hold it to the motor and 1 17 mm bolt goes through the mount...
Remove mount...and jack motor up some for easier access to pulleys/bolts

9th, use RW and spin the water pump bolts to loosen them and take them off pull pulleys off look at how they are put in because you can install them backwards....

10th, pull all belts off the water pump pulley and let them hang or whatever....

11th, remove all 10mm bolts holding on the lower timing cover make some sort of system so you dont mix all the bolts up...they have different lengthes and what not...Use a piece of cardboard and make a sketch and cut little holes and put bolts in them holes ...(DO NOT MESS WITH THE MIDDLE TIMING COVER, IT DOES NOT NEED TO COME OFF...) Sorry bout that but when I took my middle timing cover off I snapped it in 3 place....bought a brand new one from JNZ for like $37...went to install it....Shit snapped that one as well...but even worse...I said screw it and I aint messing with it again I'll run without one...

12th, pull lower timing cover off...Find crank sensor...easy to spot only sensor down by crank bolt...Disconnect crank sensor from front case and its electrical connector by the upper timing cover(Triangle plug)....

13th, rotate motor until you can slide the crank sensor out, cut old crank sensor off, use cutters whatever....

14th, Now the tricky part...Slide new sensor in behind the belt...but you will have to twist the belt in order to do so...I used a pair of flat pliers that didnt have any grooves on them to twist the belt...Make sure you push all the little clips in before you bolt the sensor back on and everything...

15th, Put everything back together and go for a drive....

If you take your time and your garage is organized this should take you no longer that 2 hours tops...I did up to step 5 went in got a drink, came out step 8, back in for another drink, back out, then down to step 4, took a piss, back out, and done... took me 2 hours to do all the above

^^^ Great write up
Here's a pic of the CPS installed: http://www.dsmtuners.com/forums/attachment.php?attachmentid=101218&d=1254638218

BTW: On the above 5th and 9th steps he means the water pump PULLEY bolts (not the water pump bolts).
