download
Why is your vehicle being recalled? Your vehicle may have a condition in which the crankshaft position sensor can fail intermittently or permanently. If the sensor fails intermittently, the Service Engine Soon (SES) light may illuminate and the vehicle may run rough. In addition, the engine may stall, and if so, may re-start immediately or after a cool down period. If the sensor fails permanently, the engine will quit running and will not re-start. If this happens while the vehicle is moving, a crash could result without prior warning. What will we do? Your GM dealer will replace the crankshaft position sensor. This service will be performed for you at no charge . Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the actual service correction time of approximately one hour and twenty minutes. What should you do? You should contact your GM dealer to arrange a service appointment as soon as possible. Bring the enclosed customer reply form with you when you visit your dealer. The form identifies the repairs required. If you no longer own this vehicle, please let us know by completing the form and mailing it back to us. Did you already pay for this repair? The enclosed form explains what reimbursement is available and how to request reimbursement if you have paid for repairs for the recall condition.

1. Disconnect the speed/timing connector “P9/J9″ (2) . Inspect the connector for the following conditions. * Corrosion * Bent pins * Missing pins * Damaged sockets * Mismating * Broken wires 2. Remove the Speed/timing sensor (1) from the front gear cover. 3. Examine the plastic end of the sensor for signs of wear or contaminants such as metal filings. The plastic end of the speed/timing sensor should have no contaminants and should show no wear (greater than 0.051 mm (0.0020 inch) from the face) . 4. Use a screwdriver to carefully pry the plastic sensor end to the fully extended position (approximately 4.775 mm (0.1880 inch) beyond the metal housing of the sensor). 5. Gently push in on the plastic end of the sensor. The plastic end should be firm. The plastic end should resist movement in the retract direction. If there is no resistance replace the sensor 6. Remove the two bolts (3) and remove the cover (5) from the flywheel housing. This hole is used for engine turning. 7. Put one bolt (3) in the timing bolt location (4) . The timing bolt location is approximately 127 mm to 152 mm (5 inch to 6 inch) above the hole in the flywheel housing for engine turning. I 8. Use 9S-9082 Engine Turning Tool (6) and a 1/2 inch drive ratchet wrench to turn the engine flywheel in the direction of normal engine rotation. The normal engine rotation is in a counterclockwise direction when viewed from the flywheel end. Turn the engine flywheel until the timing bolt engages with the threaded hole in the flywheel. Note: Visually check the location of the tooth on the wheel on which the speed/timing sensor is to be positioned. The end of the sensor must be in alignment with a tooth on the wheel and not in alignment with the valley of the wheel. Note: The No. 1 piston must be at either top center of the compression stroke or at top center of the exhaust stroke. 9. Inspect the speed/timing sensor before installation. Use steps 3 through step 6 to inspect the sensor. 10. If the sensor end is not fully extended, use a screwdriver to carefully pry the plastic sensor end to the fully EXTENDED position approximately 4.775 mm (0.1880 inch) beyond the metal housing of the sensor.

Correction Important: For ease of reassembly, shift the transfer case assembly to 2HI for the NV263 (NP1), or Neutral for the NV246 (NP8) prior to removing any components. For information on placing the NV246 (NP8) transfer case in NEUTRAL, see the procedure at the end of this bulletin. 1. Remove the transfer case and front axle/engine skid plates (if equipped). 2. Disconnect and position the front propeller shaft aside. 3. Disconnect the transfer case encoder motor wiring harness. 4. Remove the three (3) bolts that retain the encoder motor to the transfer case. 5. Separate the encoder motor assembly from the transfer case and place it on a work bench. Important: DO NOT REMOVE THE SCREWS INDICATED WITH THE (1) IN THE ABOVE ILLUSTRATION. 6. Remove the four screws on the outer perimeter of the encoder motor housing. Important: For proper timing and ease of reassembly, hold the gear in place as your remove the cover from the encoder motor assembly with your thumb or finger. 7. Carefully remove the cover from the encoder motor assembly. The cover has a seal on the bottom side. Place the cover in a position to protect this seal from damage and/or contamination. Important: Observe the location of the punch mark on the large gear in relation to the timing mark on the housing if the transfer case was placed in the 2HI for the NV263 (NP1), or Neutral for the NV246 (NP8). The timing marks should be within one tooth of proper alignment. If not, you must note the timing mark positions for reassembly. 8. Locate the two shims; one on the small gear and another on the larger gear. Set them aside on a clean surface for reuse. Important: After removing the large gear from the housing, a dark gray phenolic spacer should remain in the casting where the bottom of the large gear resides. Locate this spacer and save for reuse. 9. Carefully lift the large gear from the housing. The sensor and wiring harness will come with the gear. 10. Disconnect the wiring from the sensor. 11. Separate the sensor from the large gear.
