Camshaft Position Sensor

This procedure covers removal and installation of the camshaft position sensor on the 1992 Dodge Viper 8.0L V10 engine, including electrical disconnection and valve cover access if required.

Warnings

Tools required

Parts

• Camshaft position sensor × 1 — Use OEM specification
• Valve cover gasket (if disturbed) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and apply parking brake
2. Allow engine to cool completely (minimum 2 hours after operation)
3. Disconnect negative battery cable to prevent electrical shorts
4. Locate the camshaft position sensor on the engine (typically mounted at the front timing cover or rear of cylinder head)

Procedure

1. 1

   Access the camshaft position sensor
   On the 1992 Viper V10, the camshaft position sensor is located within the distributor assembly mounted at the rear of the engine block; verify the exact configuration against the factory service manual before proceeding. Clear any air intake components or wiring harnesses that obstruct access to the sensor. If necessary, remove ignition coil packs or spark plug wire looms to improve clearance. The sensor mounting method and fastener count must be verified against the factory service manual, as the sensor is housed within the distributor assembly on this platform rather than bolted directly to the timing cover or cylinder head.
   ℹ️Take note of all wire routing and component positions for reassembly reference. Consider taking photos.
2. 2

   Disconnect electrical connector
   Locate the electrical connector on the camshaft position sensor. Press the locking tab or release mechanism and carefully pull the connector straight off the sensor. Do not pull on the wires themselves. Inspect the connector for corrosion or damage to pins and seals.
3. 3

   Remove sensor mounting bolts
   Remove the fasteners securing the camshaft position sensor / distributor to its mounting location, using the socket size specified by the factory service manual. Keep these bolts in a clean container as they will be reused unless damaged. Note the orientation and position of the sensor before removal.
4. 4

   Extract the sensor
   Carefully pull the camshaft position sensor straight out from its mounting bore. The sensor may require slight twisting motion to break any seal or corrosion. If resistance is encountered, do not force it; apply penetrating oil and allow time to soak. Remove and discard the old O-ring seal from the sensor or mounting bore.
   ⚠Do not pry against the sensor body or mounting surface as damage may result in oil leaks or sensor mounting issues.
5. 5

   Clean mounting surface
   Thoroughly clean the sensor mounting bore and surrounding area using a clean rag and brake cleaner. Remove all old gasket material, debris, and oil residue from the mounting surface. Use a small pick or wire brush if necessary, taking care not to score the aluminum surface. Inspect the bore for cracks or damage.
6. 6

   Prepare new sensor
   Remove the new camshaft position sensor from its packaging and verify it matches the old sensor in connector type and body configuration. Install the new O-ring seal onto the sensor body if not pre-installed. Lightly coat the O-ring with clean engine oil to ease installation and ensure proper sealing.
7. 7

   Install new sensor
   Align the new camshaft position sensor with the mounting bore, ensuring proper orientation. The sensor body typically has an alignment feature or flat that matches the bore. Gently push the sensor into the bore until it seats fully against the mounting surface. Do not force; the sensor should slide in smoothly with the lubricated O-ring.
8. 8

   Install and torque sensor bolts
   Thread the 2 mounting bolts by hand to ensure proper thread engagement. Using a torque wrench and the correct socket, tighten the fastener(s) evenly to the torque specified in the factory service manual for this application. This ensures even loading and proper sensor alignment.
   ⚠Over-tightening can crack the sensor body or strip threads in the aluminum mounting surface.

9. 9

   Reconnect electrical connector
   Align the electrical connector with the pins on the camshaft position sensor and push firmly until the locking tab clicks into place. Gently tug on the connector to verify it is fully seated and locked. Ensure no pins are bent or damaged during connection.
10. 10

    Reinstall access components
    Reinstall any ignition coils, spark plug wire looms, air intake components, or wiring harnesses that were moved or removed for access. Ensure all fasteners are properly tightened and all electrical connections are secured. Route wiring exactly as originally positioned to prevent chafing or interference.
11. 11

    Reconnect battery and clear codes
    Reconnect the negative battery cable. If a diagnostic trouble code was stored, it can be read and cleared using the Chrysler OBD-I key-cycle procedure or a compatible DRB/OBD-I diagnostic tool; codes may also clear after several key cycles once the PCM confirms proper sensor operation.

Reassembly

1. Verify all electrical connections are fully seated and locked
2. Confirm all access components and fasteners are properly reinstalled
3. Double-check that no tools or parts were left in the engine compartment

Verification

• Start the engine and verify it runs smoothly without misfires or rough idle
• Check for oil leaks around the sensor mounting area after engine reaches operating temperature
• Use a scan tool to verify the camshaft position sensor signal is being received by the PCM and no DTCs are present
• Perform a test drive to confirm normal engine operation under various load conditions
