How to Match This Part
This aftermarket camshaft position (CMP) sensor replaces Suzuki Marine 33220-84M10 (also catalogued as 33220-84M10-000 / 3322084M10000). It mounts on the cylinder head, reads camshaft / cam-pulley position, and feeds the engine control module so sequential fuel injection and ignition stay synchronised on the Suzuki four-stroke outboards listed below.
Match this part in this order:
1. Number on the sensor you remove — 33220-84M10 or 33220-84M10-000
2. Engine model — DF9.9B, DF15A, or DF20A against the compatibility table
3. Body shape — compare the product images to your original sensor
Identify the sensor by form as well as by number. The unit is an L-shaped moulded black plastic body with a cylindrical probe barrel, a pre-fitted black O-ring on the barrel, a single flat mounting ear with a metal bushing for one retaining bolt, and a rectangular sealed 3-pin electrical connector. If your original sensor looks different or carries an unrelated Suzuki number, do not use this part even if the horsepower overlaps.

Installation Guide
- 1Turn the ignition off and disconnect the negative battery cable before touching any engine wiring.
- 2Locate the CMP sensor on the cylinder head using your Suzuki parts diagram, release the connector lock, and unplug the harness.
- 3Remove the single retaining bolt from the mounting ear and withdraw the old sensor straight out of its bore. Confirm the old O-ring comes out with it and is not left inside the head.
- 4Wipe the bore clean of oil and debris, compare the old and new sensors side by side, and lightly lubricate the new O-ring with clean engine oil.
- 5Push the new sensor fully home without twisting the O-ring, align the mounting ear, then fit and tighten the bolt to the torque given in your Suzuki service manual.
- 6Reconnect the harness until the latch clicks, reconnect the battery, clear stored fault codes with a marine diagnostic tool if needed, then start the engine and confirm a steady idle and clean throttle response.
Note: Professional installation is recommended for camshaft position sensors on EFI four-stroke outboards.
Troubleshooting & FAQ
Important Notes
- Verify that the product images and the number on your original sensor match 33220-84M10 / 33220-84M10-000, including the L-shaped body, O-ring barrel, single mounting ear, and 3-pin connector. If anything differs, do not proceed even if your horsepower overlaps.
- This listing covers Suzuki DF9.9B, DF15A, and DF20A applications that use this SENSOR ASSY. Confirm fitment against your engine’s parts diagram when serial-specific diagrams are available.
- This is an aftermarket replacement and is not a genuine Suzuki Marine OEM component.
- Handle the sensor tip carefully. Dropping the sensor or forcing it into a dirty bore can damage the sealing surface and cause intermittent signal faults.
- Professional installation is recommended for camshaft position sensors on EFI four-stroke outboards.
