Honda oil pressure sensor 37241-RNA-A01

Honda oil pressure sensor 37241-RNA-A01

Genuine Honda oil pressure sensor with part number 37241-RNA-A01, used in many modern Honda and Acura models with petrol and diesel engines. The sensor monitors oil pressure in the engine and sends a signal to the ECU and instrument cluster, switching on the oil warning light if the lubrication system loses pressure. A correctly working sensor is an important safeguard against serious engine damage.

Choosing a genuine Honda part guarantees the correct pressure range, full electrical compatibility with the car’s wiring and high resistance to temperature and vibration. It is the best choice when you are diagnosing oil pressure fault codes or replacing an ageing sensor as preventive maintenance.

When is it worth replacing the oil pressure sensor?

• the oil pressure warning light comes on even though the oil level is correct,
• diagnostic scan shows fault codes related to oil pressure,
• there are intermittent drops in oil pressure recorded in logs,
• the sensor housing is leaking, damaged or covered in oil.

Replacing the sensor is a low-cost operation compared with the risk of severe engine damage in case of a real loss of oil pressure.

FAQ – Honda oil pressure sensor 37241-RNA-A01

Does this sensor fit both petrol and diesel engines?
Yes, part number 37241-RNA-A01 is used in a wide range of Honda and Acura petrol and diesel engines. However, we always recommend a VIN check before ordering – we can do it for you.

Is an additional sealing washer required?
The sensor has a tapered thread which usually seals directly in the housing. Make sure that the seating surface is clean and tighten the sensor to the torque specified in the Honda workshop manual.

Can I keep driving with a faulty oil pressure sensor?
It is not recommended. A faulty sensor may fail to warn you about a real drop in oil pressure, which can lead to engine seizure. If the oil warning light behaves strangely, have the sensor and the lubrication system checked as soon as possible.
