Crankshaft positioning sensor?

I replacement the crankshaft positioning sensor yesterday.
When I tried to start it. It was hesitant so I gave it some gas and it stated on up. I drove it up the road about 2 1/2 miles and it was fine. Now this morning I went to start it and had the same issue didn't want to start unless I gave it some gas. Once it had cranked I left for work and got about a half mile down the road and it acted like it was going to die so I gave it a little gas but there wasn't any hope it cut off. I tried to restart but it wouldn't. Any advice?

    Ok I am not sure how helpful that was but the reason to replacing the CPS was because I have been driving the jeep since I bought it back in March on this year and haven't had any issues. Then came out to go to work and it wouldn't start. I then checked to see if I was getting fuel and I was then checked the fire and I wasn't so I checked the coil and it was fine so the sensor was the next thing on my list. Now I am not sure what the issue is. Any helpful feedback would be appreciated.

Sounds like you are back at square one....Therefore, you need to re-test the old sensor to make sure it is bad, re-test the new one to make sure it is not either defective or that it isn't hitting the flywheel. I would go further and test the remainder of the sensors on the engine as well as it is possible that another item is bad. Also make sure your fuel pump is operating properly and has good pressure. No shop tech can do a repair without proper testing,(shops spend thousands of $ on test equipment for that reason) you can't either.
Most inexpensive manuals such as chiltons or haynes have instructions for testing, and for most tests except fuel pump pressure, you can do tests using any good digital multi-meter. From here, I can't responsibly tell you what needs to be fixed, but I can tell you what to do to find the your case testing!
Good luck!!

I don't mean to be hurtfull but if you normally do not diagnose and repair you r own vehicle, you should search out the very best repair facillity nearest your home or work place before you may need one. Then if you only go there when the car problems are beyond your ability to resolve,stay with that place of business for a couple of years and give them a chance to prove themselves. Very few people do that. Now the fix! Not even the best repair faciltiy can give you an answer without having the veh and going on a road test with you driving and explaining the issuses. No road test,move on to the next shop on your list. You have to do your part. Tell them all the repairs done going back a year or so. Even if unrelated to current issues. Next be ready to spend some money and ask a lot of questions. What lead you to replace the cps?? Did it require any adjustment or just bolt on? Other things to consider. Gas filter -clogged,Throttle position sensor or Throttle Body -worn out, Other sensors related to Fuel Management. MAP,MAFS.MAT,MAF. You should start with a scan for codes keeping in mind most people think that tells you what and how to make the repairs but it does not, it's a starting point. A no start is as you know is a failure of at least only part in the vehicles may complex systems. It takes year or decades to become half decent at this type of repairs. Let us know how you make out

DTC P0016: Crankshaft Position (CKP) - Intake Camshaft Position (CMP) Correlation Bank 1
DTC P0017: Crankshaft Position (CKP) - Exhaust Camshaft Position (CMP) Correlation Bank 1

• An actuator that is in the full advance or retard position can cause this DTC to set.
• The presence of DTCs P0008 and P0009 along with P0016, P0017, P0018, and P0019 indicates a possible condition with the primary timing chain and the alignment between both intermediate sprockets and the crankshaft. Or, the crankshaft reluctor wheel has moved and is no longer referenced to top dead center (TDC).
• Observing the desired and actual camshaft angle parameters, with a scan tool before a DTC sets, may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

Now do you want to change a sensor an have it not fix the problem .

I replaced my crankshalf sensor and now it wont start on 01 buick lesabre 3800s 2 engine?

Did you do a
Crankshaft Position System Variation Learn ?
The crankshaft position system (CKP) variation compensating values are stored in the powertrain control module (PCM) non-volatile memory after a learn procedure has been performed. If the actual crankshaft position system variation is not within the crankshaft position system variation compensating values stored in the PCM, DTC P0300 may set, refer to Diagnostic Aids for DTC P0300 .
The Crankshaft Position System Variation Learn Procedure should be performed if any of the following conditions are true:
• DTC P1336 is set
• The PCM has been replaced
• The engine has been replaced
• The crankshaft has been replaced
• The crankshaft harmonic balancer has been replaced
• The crankshaft position sensor has been replaced

It started dying only sometimes, if you let it set 5 min or so it will start again. Drive it all day runs great then pull into parking lot or stop sign and it dies. Turns over fine but does not fire....

The Catera has a history of stalling/cutoff issues. Many are solved with the replacement of the crankshaft position sensor. It does give the symptoms you describe. I would try that first as it is fairly cheap and easy to replace. If the problem persists after that, you've at least removed one potential possibility.

25597730-01vm304gptfsbcx1qe0tia2u-3-1.jpgThis is the description of the crank sensor from AUTOZONE (cost $44.99 USD)

  • The crankshaft position sensor identifies position of the crankshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM)
  • When not replaced, vehicle may experience no start, hard start, intermittent engine shut down, misfire, engine cut out, excessive fuel consumption, CEL illumination and/or failed emission test
  • Proper alignment, positioning and spacing for faster, easier installation
  • Designed to meet or exceed OE specifications in form, fit and function

High idle stalls at lights code for crank sensor

Crankshaft and Camshaft Position Sensors Camshaft Position Sensor Engine timing is determined from the relationship between the crankshaft and camshaft. This relationship is maintained by a timing chain or timing belt. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. The Engine Management System (EMS) uses signals generated by the camshaft position sensor to synchronize fuel injection to the valve sequence and for the on-board diagnostic procedure for misfire detection. The EMS energizes the injector at or near the time the intake valve opens. For misfire diagnosis, the EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses Diagnostic Trouble Codes (DTC’s) should be stored in the EMS.
If the camshaft position sensor or circuit is faulty most engines will start. Some engine management systems will then default to a pre-programmed injector firing sequence. All injectors may be energized simultaneously or all of the injectors on one bank may be energized at the same time. If the CMP data is required for misfire detection and reliable CMP data is not present misfire detection would probably be suspended.
Related Symptoms The following symptoms can be caused by an intermittent wiring connection or faulty signal to the EMS:
  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Stalling on acceleration
Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms: No Start/Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit

Crannkshaft senser

Hello , my name is JShreader. Thank you for choosing

There are 2 Crankshaft Position Sensors on this Engine. The 7X Crankshaft Position Sensor, a Magnetic Sensor, is bolted to the lower right side of the Engine Block.
The 24X Crankshaft Position Sensor, secured in an aluminum mounting bracket and bolted to the front left side of the Engine Timing Chain Cover, is partially behind the Crankshaft.
I hope this helps you. If you have any more questions or need any more diagrams, please don't hesitate to ask...Thanks again, JShreader!
