🔌 Function

The sensor generates a signal as the crankshaft pulser passes its sensing element.

The ECM uses this signal for ignition timing, fuel-injection timing, engine-speed calculation and starting control.

Common signs of failure:

• Engine cranks but will not start

• Intermittent stalling

• Loss of ignition or injector command

• Tachometer signal is erratic

• Crankshaft-position fault code

• Engine stops when warm

• Damaged connector or wiring

• Metal contamination on the sensor tip

• Incorrect sensor clearance

Recommended checks before installation:

• Confirm the connector and wire length

• Inspect the pulser plate

• Check the sensor air gap

• Test supply, ground and signal circuits

• Inspect the harness for chafing

• Clear fault codes and verify engine-speed data after installation

📦 Condition

• Genuine Honda used part

• Pre-owned electronic sensor

• Cosmetic marks and connector wear may be present

• Electrical testing before installation is recommended

• Supplied in protective or equivalent packaging
