After replacement of crankshaft position sensor, the computer needs to have the crankshaft position system variation learn procdeure performed. That requires a factory scan tool. Crankshaft Position Sensor Replacement Removal Procedure

1. Disconnect the negative battery cable.Raise and support the vehicle. .
2. Remove the crankshaft harmonic balancer. Disconnect the crankshaft position (CKP) sensor electrical connector.
3. Remove the CKP sensor shield (1). DO NOT use a pry bar.
   
   
   
4. Remove the CKP sensor studs.
5. Remove the CKP sensor.

1. Install the CKP sensor. 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 studs. Tighten
   Tighten the studs to 30 N·m (22 lb ft).

the egr value tubing also gets corroded with carbon. take tube off and use a wire brush to clean tubing. i talked with a mechanic and he said he has never seen an egr valve fail. most if not all egr problems are due to carbon build up in the egr tube. clean egr tube interior.

3.8L Engines

1. Disconnect the negative battery cable.
   
2. Remove the serpentine belt(s) from the crankshaft pulley. Please see Section 1.
   
3. Raise and safely support the vehicle.
   
4. Remove the right front tire assembly. Remove the right inner fender access cover.
   
5. A flywheel holding device such as GM's J 37096 is required to keep the crankshaft from turning as the crankshaft balancer is being removed. Install this holding tool or its equivalent. Please see Section 3 for more information.
   
6. Using a 28mm socket, remove the crankshaft harmonic balancer retaining bolt. Using special tool J 38197 or equivalent balancer removal tools, drawn the balancer from the end of the crankshaft. Please see Section 3 for more information.
   
7. There is a roughly circular aluminum shield that protects the crankshaft position sensor; remove this shield. Use care not to damage it. Do not pry to remove.
   
8. Detach the electrical connector from the crankshaft position sensor, remove the attaching bolts and separate the sensor from the engine block face.
   

1. Clean all parts well. Position the crankshaft sensor to the block face and tighten the bolts to 14–28 ft. lbs. (20–40 Nm).
   
2. Install the crankshaft position sensor shield. Verify that the electrical connector is secure.
   
3. Install the crankshaft balancer. Please see Section 3.
   
4. Torque the crankshaft balancer center bolt to 110 ft. lbs. (150 Nm), plus an additional 76 degrees.
   
5. Install the inner fender access cover and the right front tire assembly. Wheel nut torque is 104 ft. lbs. (140 Nm).
   
6. Lower the vehicle.
   
7. Install the serpentine belt(s), as outlined in Section 1.
   
8. Connect the negative battery cable.
