Customer Question
I have a 2002 oldsmobile...
I have a 2002 oldsmobile intrigue, the crankshaft sensor needs replaced and there is also a temperature problem with the car running too cold... Are these difficult to fix on my own, if so how? If I need to take the car to a garage, how much would it be to fix these problems?

Reply to Dan's Post: My car is 2002 Oldsmobile Intrigue 6 cylinder with about 110,000 miles. I took my car to auto zone and a tech hooked a computer to the car and told me about both of the errors- the coolant system and the crankshaft malfunction error.
Auto Mechanic: Dan, Auto Service Technician replied 10 years ago

The engine running too cold may be a faulty thermostat not regulating the engine temperature and I would try that first. Here are directions to replace the thermostat, temperature sensor and crank sensor (the crankshaft relearn needs to be performed at a dealership as the Tech 2 scan tool needs to be used).

Crankshaft Position Sensor Replacement

Removal Procedure


    Object Number: 350551  Size: SH
    Click here for detailed picture of above imageidth=
  1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure in Engine Electrical.
  2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  3. Remove the starter motor. Refer to Starter Motor Replacement in Engine Electrical.
  4. Disconnect the crankshaft position (CKP) sensor electrical connector.
  5. Remove the CKP sensor bolt (1).
  6. Remove the CKP sensor (2) from the engine block:
    Remove the sensor by pulling on the sensor connector. DO NOT pry on the bracket.
    DO NOT rotate or twist the sensor or damage the mounting bracket if the sensor is being reused.

Installation Procedure

Important: When replacing the CKP sensor with a new sensor or reinstalling the original sensor, use the following recommended procedures:

Ensure that the CKP sensor bore is completely free of any foreign material, such as old O-ring, dirt, burrs, etc.
Ensure that the flange on the CKP sensor bore is not damaged.
Clean all the mounting surfaces before re-installing any components.
Inspect the CKP sensor and replace the sensor if any of the following conditions are present:
- The bracket is damaged.
- The bottom of the brass housing exhibits any damage.
- Never install a sensor that has been dropped.
Lubricate the O-ring on the sensor with clean engine oil prior to installing the sensor .
Inspect all the connectors for any damaged terminals.

  1. Install and fully seat the CKP sensor (2) into the engine block.

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  2. Install the CKP sensor bolt (1).

    Tighten

    Tighten the bolt to 9 N·m (80 lb in)

  3. Ensure that the CKP sensor mounting flange is contacting the engine block.
  4. Connect the CKP sensor electrical connector.
  5. Install the starter motor. Refer to Starter Motor Replacement in Engine Electrical.
  6. Connect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure in Engine Electrical.
  7. Lower the vehicle.
  8. The CKP System Variation Learn Procedure must be performed after replacing the CKP sensor. Even if the original sensor is reinstalled, the Learn Procedure must be performed.
  9. Engine Coolant Temperature Sensor Replacement

    Removal Procedure

    Notice: Use care when handling the coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.

    1. Partially drain the cooling system. Refer to Draining and Filling Cooling System in Engine Cooling.
    2. Remove the exhaust gas recirculation (EGR) inlet pipe. Refer to Exhaust Gas Recirculation (EGR) Inlet Pipe Replacement .

    Installation Procedure

    Notice: Use care when handling the coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.

    Notice: Replacement components must be the correct part number for the application. Components requiring the use of the thread locking compound, lubricants, corrosion inhibitors, or sealants are identified in the service procedure. Some replacement components may come with these coatings already applied. Do not use these coatings on components unless specified. These coatings can affect the final torque, which may affect the operation of the component. Use the correct torque specification when installing components in order to avoid damage.
