Replacing a camshaft position sensor on a 1998 cutlass

The check engine light came on and had a diagnostic test done which said the camshaft position sensor is going bad. I replaced my front struts about a week ago and im not sure if any wires were pulled or anything that would make it show up bad or if it just needs replaced. My car still starts and i havent noticed it taking longer to start, i tried looking online for a diagram or information to find the sensor but have had no luck

The cam sensor is integrated with the crank shaft sensor behind the crank shaft pulley. The 3.1 runs 2 crank sensors. the one behind the crankshaft pulley in integrated to act as a cam sensor. It has 2 sets on rings for that sensor, 1 is in use accustomed for the fuel timing
Good luck and hope this helps friend.

What's an SVG?

Scalable Vector Graphics, SVG for short, is an XML-based format for 2D images, allowing them to be viewed both static and interactive. This makes us able to provide you with a fully interactive image full of links to related diagrams and documents straight from the OEM.

Click on any link within the document and you will be able to narrow your focus on a particular component, or view a related portion of a wiring diagram. Even more, these documents are fully zoomable and printable.

Camshaft position sensor A code


Just because you have a code for that sensor it doesn't mean the sensor is defective and in this case it is seldom the cause of the code. See your local dealer for diagnosis and testing before replacing any parts. Never listen to parts persons about diagnostic code fixes, they know nothing about the system.

My car is showing PO344 (Camshaft Position Sensor A Circuit Intermittent) as a problem it's having... I replaced the camshaft sensor about 2 years ago when I was having a similar problem; could the sensor...


All ways, the camshaft position sensor signal sent to the ECM is intermittent

The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Powertrain Control Module (PCM) or Electronic Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.

When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.

When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

Check thos DTC diagnostic and possible solutions about P0344 - Camshaft Position Sensor Circuit Intermittent

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall

Possible causes
- Harness or connectors (The sensor circuit is open or shorted)
- Camshaft position sensor may be faulty
- Camshaft (Intake) may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead (Weak) battery

Possible solution
- Charge battery
- Repair harness or connector
- Replaced Camshaft Position Sensor.
Tech notes
- Sometimes and in some models, low battery voltage or a weak starter can can trigger a Camshaft Position Sensor code.


Hope this helps.

When replacing the camshaft position sensor on a 6cyl, which peripherals have to be removed?


Not much if anything. The cam sensor sits right on top of the engine, at the front, one screw to remove, and pull it out.

Where is the camshaft position sensor located on a 1997 Oldsmobile Cutlass Supreme 3.1 ?


Removal & Installation 3.1L Engine To Remove:
CMP sensor 93174g24.gif

  1. Disconnect the battery ground cable.
  2. Remove the power steering pump and set aside with the lines connected.
  3. Disconnect the camshaft position (CMP) sensor electrical connector.
  4. Remove the CMP mounting bolt.
  5. Remove the CMP sensor.
  6. Check the O-ring for damage and replace if necessary.
To Install:
NOTE: Lubricate the O-ring with clean engine oil.
  1. Install the camshaft position sensor.
    • Tighten the mounting bolt to 89 in lb (10 Nm).
  2. Connect the CMP sensor electrical connector.
  3. Install the power steering pump.
3.4L Engine To Remove:
  1. Disconnect the negative battery cable.
  2. Detach the electrical connector from the camshaft position sensor.
  3. Remove the sensor retainer bolt and carefully pull the sensor from the camshaft carrier. An O-ring seal may hold the sensor in place. Use care not to lose the O-ring.

To Install:
  1. Installation is the reverse of the removal procedure.
  2. Before installing a replacement camshaft sensor, lubricate the new O-ring with clean engine oil.
    • Tighten the bolt to 88 inch lbs. (10 Nm). Do not over-tighten.
  3. Connect the negative battery cable.
3.8L Engine To Remove:
  1. Disconnect the negative battery cable.
  2. Detach the electrical connector from the camshaft position sensor. Camshaft Position Sensor removal (3.8L engines) 93174g26.gif

  3. Remove the retaining screw and separate the sensor from the front cover.
To Install:
  1. Installation the sensor in the front cover.
  2. Tighten the bolt to just 44 inch lbs. (5 Nm). Do not over-tighten. Verify the electrical connector is secure.
  3. Connect the negative battery cable.

Motor turns over but no spark changed coil and crank shaft sensor


well replace lots of coils but same with crank sensor on these trucks
  • For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. To perform a complete test of the Camshaft Position Sensor and its circuitry, refer to the DRB II diagnostic tester. Also see the appropriate Diagnostic Charts. To test the sensor only, refer to the following: See: Testing and Inspection
  • Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips.
PROCEDURE
  1. Connect the positive (+) voltmeter lead into the sensor output wire. This is done at the distributor wire harness connector.
  2. Connect the negative (-) voltmeter lead into the ground wire.
  3. Set the voltmeter to the 15 Volt DC scale.
  4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup.
  5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts .
  6. If voltage is not present, check the voltmeter leads for a good connection.
  7. If voltage is still not present, check for voltage at the supply wire.
  8. If voltage is not present at supply wire, check for voltage at pin-7 of Powertrain Control Module (PCM) 60-way connector. Leave the PCM connector connected for this test.
  9. If voltage is still not present, perform vehicle test using the DRB II diagnostic scan tool.
  10. If voltage is present at pin-7, but not at the supply wire:
    1. Check continuity between the supply wire. This is checked between the distributor connector and pin-7 at the PCM. If continuity is not present, repair the harness as necessary.
    2. Check for continuity between the Camshaft Position Sensor output wire and pin-44 at the PCM. If continuity is not present, repair the harness as necessary.
    3. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary.
  1. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. NOTE: If sync pulse signal is not present, replacement of the Camshaft Position Sensor is necessary.
