After replacing the sensor did you get your vehicle checked via a PC for proper calibration, since you have changed a sensor so you got to set the parameters too to indicate or trigger an alarm. This is standard procedure whenever sensors are replaced to evaluate its sensing capabilities with the help of a PC at the service station................sodeep

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

Need to know the location of both crankshaft position sensor on 2008 Chevrolet hhr plz thx


Only has one crankshaft position sensor ,an cam sensors . To change the crank sensor u would have to pull the starter ,located above starter .
Camshaft Position Sensor Replacement - Intake Camshaft Position Sensor Replacement - Exhaust
After a crank sensor replacement a
Crankshaft Position System Variation Learn has to be done !
Important: The crankshaft position (CKP) system variation learn procedure is required when the following service procedures have been performed, regardless of whether DTC P0315 is set:
?€¢
Engine replacement


?€¢
Engine control module (ECM) replacement


?€¢
Crankshaft damper replacement


?€¢
Crankshaft replacement


?€¢
CKP sensor replacement


?€¢
Any engine repairs which disturb the crankshaft to CKP sensor relationship

Important: The scan tool monitors certain component signals to determine if all the conditions are met to continue with the CKP system variation learn procedure. The scan tool only displays the condition that inhibits the procedure. The scan tool monitors the following components:
?€¢
CKP sensor activity--If there is a CKP sensor condition, refer to the applicable DTC that set.


?€¢
Camshaft position (CMP) signal activity--If there is a CMP signal condition, refer to the applicable DTC that set.


?€¢
Engine coolant temperature (ECT)--If the engine coolant temperature is not warm enough, idle the engine until the engine coolant temperature reaches the correct temperature.

Where is the crankshaft position sensor located on a 2008 HHR 2.2 is that ecotec engine


My info says it is located above the starter motor. Info says to remove the starter.

The info also says you have to do a crankshaft variation relearn procedure. I can't help you with that procedure.

Where is the 2nd crank shaft sensor located, and is there a diagram to show where these sensors are located?


is it a no crank or crank no start?
Possible causes for code P0335
- Faulty crankshaft position sensor
- Crankshaft position sensor harness is open or shorted
- Crankshaft position sensor circuit poor electrical connection
- Signal plate may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead or weak battery

P1336 gm code


P1335 CHEVROLET P1335 CHEVROLET - Crankshaft Position Circuit Possible causes
- Faulty Crankshaft Position Sensor
- Crankshaft Position (CKP) Sensor harness is open or shorted
- Crankshaft Position (CKP) Sensor circuit poor electrical connection help.png Help with this
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall
P1335 CHEVROLET Description
The Crankshaft Position (CKP) sensor sends pulses to the Powertrain Control Module (PCM) as the reluctor wheel teeth rotate past the CKP sensor. The PCM uses the CKP pulses to synchronize the ignition and fuel injector operation, and to time the interval between each CKP pulse. The PCM determines when an excessive change in crankshaft speed occurs by comparing each new time interval with the previous interval. A misfire causes an unexpected change in the crankshaft speed. A certain amount of acceleration/deceleration is expected between each firing stroke, but if the crankshaft speed changes more than an expected amount, the PCM interprets this as a misfire. The interval between CKP sensor pulses is extremely small. At high engine speeds, slight variations in the following components make misfire detection difficult:
- Crankshaft
- Reluctor wheel
- CKP sensor
The PCM learns variations during the Crankshaft Position System Variation Learning Procedure. The PCM compensates for these variations when performing detect misfire calculations. Only a scan tool can command the PCM to perform the Crankshaft Position System Variation Learning Procedure again.
Perform the learning procedure after the following actions:
- A PCM replacement
- Any operation or repair involving the crankshaft, the CKP sensor, or the CKP sensor to reluctor wheel gap relationship.
- An engine replacement.
- The ignition switch is in the ON position until the battery is drained.

1997 dodge dakota how many volts does the crankshaft position sensor require


Code 320 is a problem with the tach signal which could be the crank or cam sensor.
Code 351 is a problem with the positive or negative circuit to the coil.
And code 1391 is for a problem with the ABS system which would not involve the engine running.
The sensors get a 5 volt reference from the computer and the return signal is what the computer "watches".
I would make sure you have battery voltage on the positive side of the coil and see if you have a ground reference from the computer.
You may need a shop manual to get the procedure to troubleshoot the ignition system.

Error Code P0315 on 2007 Chevy Aveo


P0315 - Crankshaft Position System Variation Not Learned

Possible causes- Crankshaft Position (CKP) sensor harness is open or shorted
- Crankshaft Position (CKP) sensor circuit poor electrical connection
- Faulty Crankshaft Position (CKP)
- Damaged crankshaft pulse wheel teeth. Tech notes Visual inspection of the Crankshaft Position (CKP) sensor and crankshaft pulse wheel teeth for damage. If crankshaft teethes are OK, replaced the Crankshaft Position sensor

My car got FS engine. it cranks but no spark on plugs.replaced another distributor still got same problem.supply is on connector.


TESTING
  1. Disconnect the crankshaft position sensor wire harness plug.
  2. Connect an ohmmeter to the sensor terminals A and B and measure the resistance. Fig. 1: Crankshaft position sensor connector terminals. Measure the resistance across the A and B terminals 89544g27.gif
    Fig. 2: Measure the air gap between the crankshaft position sensor and the crankshaft pulley 89544g28.gif

  3. The reading should be 520–580 ohms at 68°F (20°C).
  4. If not as specified, replace the sensor.
  5. Measure the air gap of the sensor between the crankshaft pulley and the sensor.
  6. Proper air gap should be 0.040–0.080 in. (1–2 mm).
  7. If not as specified, inspect the crankshaft pulley and/or replace the sensor.
