This oil pressure switch monitors the engine's lubricating oil pressure and signals the control system or dashboard if pressure drops below a safe operating level. It is manufactured to precise OEM specifications, providing reliable activation compared to a worn switch that may fail to trigger or provide false readings. Operators may notice an illuminated oil pressure warning light on the dashboard or an engine shutdown event if this switch malfunctions.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A faulty oil pressure switch may initially cause intermittent illumination of the oil pressure warning light, or it may fail to illuminate at all when pressure is low. If the switch fails to signal a low-pressure condition, the engine could continue to run without lubrication, leading to severe internal wear and potential seizure. Conversely, a switch that falsely indicates low pressure can lead to unnecessary downtime.
Ensure the engine is completely cool before attempting to remove the old switch to avoid burns. Apply a small amount of thread sealant to the threads of the new switch, but be careful not to get any sealant into the switch's electrical connector.
When replacing the oil pressure switch, it is advisable to check the engine oil level and condition, and inspect the oil filter for any signs of blockage.
