Camshaft Position Sensor

This procedure covers the replacement of the camshaft position sensor on a 2017 Maserati Levante with the 3.0L V6 Twin Turbo engine, requiring removal of engine cover components to access the sensor.

Warnings

Tools required

Parts

• Camshaft Position Sensor × 1 — Use OEM Maserati specification
• O-ring seal for sensor (if not included) × 1 — Included with OEM sensor

Preparation

1. Park vehicle on level surface and engage parking brake
2. Ensure engine is completely cool to the touch
3. Disconnect negative battery terminal and wait 5 minutes
4. Remove engine cover by releasing snap-fit fasteners
5. If necessary, clear diagnostic trouble codes with scanner to verify repair after completion

Procedure

1. 1

   Remove engine cover components
   Remove the decorative engine cover by pulling upward on the front and rear to release the rubber grommets. Remove any necessary plastic covers over the timing cover area using trim tools to access the front of the engine where the camshaft position sensor is located.
2. 2

   Locate camshaft position sensor
   Identify the camshaft position sensor on the front timing cover. The 3.0L V6 Twin Turbo has sensors on each bank. The sensor is a cylindrical component with an electrical connector on top, mounted vertically into the timing cover. Note the sensor location and routing of the wiring harness for reinstallation.
3. 3

   Disconnect electrical connector
   Press the locking tab on the electrical connector and carefully pull the connector straight away from the sensor. Do not pull on the wires themselves. Inspect the connector for corrosion, oil contamination, or damaged pins. Clean with electrical contact cleaner if necessary.
4. 4

   Remove sensor mounting bolt
   Using an 8mm socket with extension, remove the single bolt securing the camshaft position sensor to the timing cover. Keep the bolt in a safe location as it will be reused unless corroded or damaged.

5. 5

   Extract camshaft position sensor
   Carefully pull the sensor straight out from the timing cover. The sensor has an O-ring seal that may cause slight resistance. Twist gently while pulling if needed, but avoid excessive force that could damage the timing cover bore. If the sensor is seized, apply penetrating oil and wait before attempting removal.
6. 6

   Inspect sensor bore and O-ring
   Inspect the sensor bore in the timing cover for debris, metal shavings, or damage. Clean thoroughly with lint-free rags and brake cleaner. Remove the old O-ring from the sensor bore if it remained in the cover. Check that the bore is clean and free of scratches that could cause oil leaks.
   ⚠Do not allow any debris to fall into the timing cover opening as this could damage the camshaft reluctor wheel or timing components.
7. 7

   Prepare new sensor
   Remove the new camshaft position sensor from packaging. Verify the new O-ring is properly seated in the groove on the sensor body. Lightly lubricate the O-ring with clean engine oil to ease installation and prevent tearing. Do not use silicone or grease on the O-ring.
8. 8

   Install new sensor
   Carefully insert the new camshaft position sensor straight into the timing cover bore. Push firmly until the sensor flange seats flush against the timing cover mounting surface. Ensure the sensor is fully seated and the mounting hole aligns with the threaded hole in the cover.
9. 9

   Install and torque sensor bolt
   Install the sensor mounting bolt and hand-tighten. Using a torque wrench, tighten the bolt to the specified torque in a smooth, continuous motion. Do not over-torque as this can crack the sensor housing.

10. 10

    Reconnect electrical connector
    Push the electrical connector onto the sensor until you hear and feel a distinct click, indicating the locking tab has engaged. Gently tug on the connector to verify it is securely locked. Ensure the wiring harness is properly routed and secured to prevent chafing.
11. 11

    Reinstall engine covers
    Reinstall any plastic covers removed for access. Reinstall the decorative engine cover by aligning the rubber grommets with the mounting posts and pressing firmly until seated. Verify all covers are secure and no tools or parts are left in the engine bay.
12. 12

    Reconnect battery and clear codes
    Reconnect the negative battery terminal. If using a scanner, clear any diagnostic trouble codes stored during the repair. The vehicle may need to relearn idle parameters during the first few drive cycles.

Reassembly

1. Ensure all electrical connectors are fully seated and locked
2. Verify engine covers are properly installed and secured
3. Double-check that no tools or rags were left in the engine compartment

Verification

• Start the engine and verify it runs smoothly without rough idle or stalling
• Check that no warning lights are illuminated on the instrument cluster
• Use an OBD-II scanner to verify no camshaft position sensor codes are present (P0340, P0341, P0345, P0346)
• Inspect the sensor installation area for any oil leaks after running the engine for several minutes
• Test drive the vehicle to confirm normal operation and throttle response
