I need to change the camshaft position sensor for my 1994 buick regal. I can't find the camshaft position sensor location. i was told that it was behind the power steering; still can't find it. Can anybody please assist me on the exact location. Thanks

I think some people (myself included) are confused between camshaft and crankshaft position sensors. I believe their are 4 camshaft position sensors in 2 banks, I’d like to know all these locations as I have p0014 and p0021 corresponding to both banks of CAM shaft sensors. Where are these locations please? I have 2009 Enclave also.

here is where it is located and here is how to change it

1. Turn OFF the ignition.
2. Remove the serpentine drive belt.
3. Disconnect the sensor electrical connector.
4. Remove the attaching bolt.
5. Remove the sensor.
6. Inspect the sensor for wear, cracks or leakage if the sensor is not being replaced.

The coolant temperature sensor is a thermistor mounted in the engine coolant stream. A thermistor is an electrical device that varies its resistance in relation to changes in temperature.

For 2.5L engines, the coolant temperature sensor is located on the left side of the cylinder head.

For MFI engines, the coolant temperature sensor is located on the intake manifold water jacket or near (or on) the thermostat housing.

Hope this helps (remember to rating this and leave an testimonial comment about this free answer).

On the 3800 V6, the camshaft position sensor is located behind the water pump pulley. if you were to look at pulley straight on, it is at about the 9 o"clock position. good-day!

you will need a puller to take off the harmonic balancer, then you will see it. it has to line up perfectly with the balancer.

When my 94 Regal GS frequently wouldn't start for 30 minutes to an hour after being driven, it was the crankshaft positioning sensor that needed to be replaced. I also replaced the harmonic balance pulley. The car ran more smoothly and started everytime.

Hello trhino69.

The Regal has two position sensors.
One on the crankshaft and another on the camshaft.
If the crankshaft sensor isn't reading it will not start.
On the other hand if the camshaft sensor isn't reading it will start but the fuel injectors will revert to non-sequential firing.
The crankshaft sensor is mounted at the crankshaft harmonic balancer.
It is #4 in the diagram below.



This should answer your question.

have had this very problem was the crankshaft position sensor failing hot, sensor is located at crank pulley on the front of the eng, kinda hard to get to.

REMOVE OR DISCONNECT

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.

INSTALL OR CONNECT:

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.

• Apply thread sealer (GM 1052080) or equivalent to the threads of the balancer bolt.

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.

It seems like it needs the idle control position sensor or the camshaft or crankshaft position sensors. Take to autoparts store for free scan for trouble code.
