Default p0336 crankshaft position sensor code

I got a p0336 code during a long road trip. This is the only time I have ever seen this code on this vehicle, a 2001 buick regal with 230K miles. I haven't noticed any performance problems. It now has gone another 1500 miles after I cleared the code, but I am worried that it could recur and possibly cause a stall, so I am thinking about replacing the crankshaft position sensor.

Has anyone done this on this vehicle? Is it a DIY job, or do you need special tools? Any pitfalls or hints?

This is what I found :


  1. Serpentine belt from the crankshaft pulley.
  2. Raise the vehicle on a hoist.
  3. Right front tire and wheel assembly.
  4. Right inner fender access cover.
  5. Using a 28 mm socket, remove the crankshaft harmonic balancer retaining bolt.
  6. Crankshaft harmonic balancer using tool J 38192 or equivalent.
  7. Sensor electrical connector.
  8. Foreign object deflector.
  9. Sensor and pedestal from block face.
  10. Sensor from pedestal.

  1. Loosely install the crankshaft sensor on the pedestal.
  2. Position the sensor with pedestal attached on special Tool J 37089.
  3. Position the special tool on the crankshaft.
  4. Bolts to hold the pedestal to the block face, torque to 20-40 Nm (14-28 lb.ft).
  5. Torque the pedestal pinch bolt to 3-4 Nm (38-40 lb.in).
  6. Remove special tool J 37089.
  7. Place the special tool 37089 on the harmonic balancer and turn. If any vane of the harmonic balancer touches the tool, replace the balancer assembly.
  8. Balancer on the crankshaft.
    1. Torque the crankshaft bolt to 140 Nm + 56(104 lb.ft + 56).
    2. Foreign object deflector.
    3. Electrical connector.
    4. Inner fender shield.
    5. Tire and wheel assembly, torque to 140 Nm (104 lb.ft).
    6. Lower the vehicle.
    7. Serpentine belt.
