Re: How to replace the camshaft sensor in a 1998 pontiac...
Here is the procedure from AutoZone repair guide.....
REMOVAL & INSTALLATION
2.4L Engine
- Disconnect the negative battery cable.
- Unplug the sensor harness connector at the sensor.
- Unfasten the retaining bolt, then remove the sensor from the camshaft housing.
To install:
- Place the sensor into position.
- Install the CMP sensor retaining bolt, then tighten to 88 inch lbs. (10 Nm).
- Attach the sensor harness connector.
- Connect the negative battery cable.
3.1L Engine
- Disconnect the negative battery cable.
- Support the engine by the oil pan.
- Unfasten the 5 bolts and one nut securing the right engine mount, then remove the mount from the vehicle.
- Remove the serpentine belt.
- Remove the 3 nuts and one bolt retaining the alternator braces, then remove the braces.
- Keeping the fluid lines attached, unfasten the 3 power steering pump retaining bolts, then remove the pump.
- Using special tool J-38125-A or equivalent, remove the camshaft position sensor. It is retained by one bolt and an electrical connector. The special tool requires the removal of the plastic connector from the wires for clearance. Do NOT cut the pigtail!
To install:
- Install the camshaft position sensor. Re-route the pigtail under the power steering pump and alternator brace. Make sure to route the pigtail away from electronic components to avoid Electromagnetic Interference (EMI).
- Install the power steering pump assembly, then the alternator braces.
- Install the serpentine drive belt, then the right engine mount.
- Connect the negative battery cable.
