Depending on year make and model, it could be a crank or cam position sensor.

Where is the camshaft sensor Saab 900se 97 ,


Crankshaft Position Sensor Replacement Guide The following is the procedure I developed to change the Crankshaft Position Sensor (CPS ) on my 1996 Saab 900S 2.3 L NA. It is a very simple part to replace, and is also a cheap part, at $42 from the dealer I bought it from (who would've thought a dealer would have a part for a good price, let alone have the part I wanted at all icon_biggrin.gif). In case you were wondering, here is how I confirmed the CPS was not working correctly. The car would not start sometimes on hot days after short trips, it would turn off if it got too hot while driving (which was scary), I could hear the fuel pump working, I checked the started for the correct charge (it was fine as I thought), I already did the Neutral Safety Switch bypass as a precaution.
Here are the steps:
1) Make sure your engine bay is cool because you will be bumping into and touching the engine block and surrounding parts during this installation.
2) Locate the CPS. It is directly across from the radiator fan, about 8 inches down from the top of the fan. I can post pictures later tonight.
3) Using the largest torx screwdriver fitting that was supplied with the car, remove the single torx screw at the upper right of the CPS.
4) Now, before you remove the CPS, trace the wire it is connected to around the right side of the engine, and up under where the plenum/TB cover would reside. I have a custom intake so I did not have to remove anything to see this connection. There is a white plug with a red plastic box that penetrates the white plug perpendicularly. Simply pull the red box away from the large white connection to allow the CPS connection and wire to fall free.
5) Now, you can either patiently route the connection you just took apart back around the engine to get the old CPS out of there, or you can take as little time as I did and simply cut the wire in half and pull the ends out.
6) The CPS should now pull right out.
7) Quickly place the new CPS into the slot in the engine block, as to avoid any debris getting in there. MAKE SURE THE OLD O-RING COMES OFF AND THE NEW O-RING GOES ON the shaft of the new CPS before pushing the part in.
8) Retorx the screw.
9) Pull the end connection through all of the tubing and parts in your way. Find the metal spring-formed arch that holds the CPS wire from jingling about and with one hand, pry it open while you push the wire under the clip to secure it. This step can be tricky, but is very important to ensure the wire does not vibrate and prematurely malfunction.
10) Do the opposite of step 4

The scaner to check the codes dont come on when conecte to it


OBD-II ports not communicating with a code scanner when caused by the CPS is because the CPS has failed. If the CPS is failed, the engine will not run.

Try another brand or model of code scanner.

1996 POWERSTROKE TURBO 7.3 DIESALCUT OFF SETING STILL OR DRIVING I MUST PUT IN NEUTRAL OR PARK TURN KEY OFF THEN RESTART SOMETIMES IT STARTS RIGHT SOMETIMES LONGER.


Have you had the Crank Position Sensor (CPS) changed? Ford had issued a recall for the CPS on the 7.3 and the symptoms you describe sound like those when the CPS starts becomming intermittent.

I am looking for the location of the CPS


Hi there,

The Crankshaft Position Sensor(CPS) is attached to the bell housing of your vehicle. The CPS detects teeth on the flywheel as they pass the sensor during engine operation and thus provides the computer with info concerning engine speed and crankshaft angle.

Hope this helps. Best of luck...

Symptoms look like a faulty crank position sensor. Remove it and give it an inspection, if it looks OK give it a clean, especially the tip. Check the electrical connection so that it is free of dirt and corrosion. If there is a spacer beneath the CPS make sure it has not got thicker due to rust, wire brush it - the CPS tip is very sensitive to crank ring proximity. Check that there is electrical continuity between the CPS electrical connections - infinite resistance = broken circuit = dead CPS. Reinstall it and see if sorts any problems out. If no improvement change the CPS for a new one.

96 Saturn SC1 (automatic): b 4 installing (CPS) crankshaft position sensor...she ran beautiful...now, rough idle and the moment she's put in gear, she stalls-out. I shimmed the sensor, she runs OK, but...


If it ran beautiful I don't see why you installed CPS. ??? 

The CPS and CAS should only be replaced if the car is stalling or shorting out. I just changed the CAS on my 95 Talon but only because it was cutting off like I turned the key off. 

If the only thing you did was change the CPS then it's not lined up right. Every car is different but the CPS usually has to be aligned.

Is spark plug working on crank shaft speed


Yes, there is a CPS (Crankshaft Position Sesnor) that signals the ECM to fire the plugs. If the engine cranks but won't start and there's no spark, it could be the CPS. Look at the tachometer while cranking the engine and see if it moves off of 0 RPM. If it doesn't, then it could be the CPS. The best way to check it is with a OBD 2 Scanner. It will give you a no crank signal code, or perhaps another code that will lead you in the right direction if it's not the CPS.

Fuel filter changed of Saturn Vue 2002


Never allow Saturn touch a Saturn.
During the oil change, the Saturn dealer loosened the center positive electrical battery cable at the main fuse box, drivers side, under hood.
The loose positive cable results in an electrical surge that wipes out the cps.
The new cps is only avaqilable from Saturn.
When the new cps is delivered, one electrical pen will be bend down and must be straightened prior to insertion of male and female electrical connector to the cps. Otherwise the new cps will fail.
Be certain to tighten the center positive post of three that secure the main fuse box in place. The center post must be tightened to ensure the new cps is not destroyed by subsequent electrical surges which result when Saturn Dealer loosens the center fuse box post.

Cause of the problem:
During a non-related visit to the Saturn dealer, ie for an oil change, the Saturn dealer loosened the center of three bolts that electrically connect the main battery plus cable to the main fuse box, driver side, under hood, near windshield.
Affect of loose electrical plus cable
A loose cable, probably on the way home from the oil change, causes electrical surges that destroy the CPS and result in catastropic engine failure.
Fix:
Replace the cps. Available only from the Saturn dealer, the new cps exchange will also result in catastrophic failure when replaced.
Problem with CPS Replacement:
The Saturn dealer will bend down one of the electrical conductors on the electrical connector to the new cps. Upon insertion of the electrical connector into the cps recepticle, the bent pen will defeat cps funcetion.
Fix for the Fix
Straighten each electrical pen to the new Saturn supplied cps. Carefully reconnect the connector to the cps making certain each pen is properly inserted.
Be sure to tighten the plus center connector that holds the main fuse box firmly connected to the main plus battery cable.

Saturn will make you pay dearly and ruin your VUE engine because you shame shame shame on you because you did not pay Saturn the big bucks demanded by Saturn to renew the inadequate Saturn maintenance agreement.
