Frequently Asked Questions
What does the genuine Honda CB oil-pressure switch control?
The oil-pressure switch completes the warning-light circuit when engine oil pressure is low. It is a warning switch, not an oil-pressure gauge or a repair for an engine that cannot build pressure.
What should be checked if the oil-pressure warning light stays on?
Stop the engine and verify oil level, switch wiring and actual oil pressure with the Honda test procedure. Do not assume a new switch will correct a blocked oil passage, worn pump or bearing-clearance problem.
How many oil-pressure switches are included?
One genuine Honda oil-pressure switch is included for one compatible engine. Confirm the Honda reference, electrical terminal and sealing arrangement against the original before installation.
