Honda 35710-SE3-A01 Genuine Oil Pressure Switch — for B/D/F/H-Series Engines

A continuously illuminated oil pressure warning light on the dashboard, a flickering oil light at idle, or no oil pressure reading on the gauge — these are common signs that your oil pressure switch is failing. The oil pressure switch sends a signal to the dashboard to indicate when oil pressure drops below a safe level. A faulty switch can cause false warnings or fail to alert you to a real drop in oil pressure, which can lead to severe engine damage. Replacing it with this genuine Honda switch restores accurate oil pressure monitoring and protects your engine.

This is a factory-original Honda oil pressure switch (OE part number 35710-SE3-A01) with a 1/8" NPT thread. It is engineered to open and close at the correct pressure threshold, providing a reliable signal to your instrument cluster. This is the same part sold at Honda dealerships.

Vehicle Fitment Table (OEM Compatibility)

⚠️ Important Fitment Notes:

• Always verify by VIN – Fitment is determined by the engine code and oil pressure port location. Some later models with K-series engines use a different switch (typically 37240-PT0-014).

• Supersession – Part 35710-SE3-A01 is superseded by 35710-SE3-A02 on some later models. Both are functionally identical, but confirm your original part number.

• Thread size – This switch has a 1/8" NPT thread. Verify that your oil pressure port matches this thread size.

• Double‑check your original part – Before ordering, confirm the part number stamped on your old oil pressure switch or run your VIN through a Honda OEM parts catalog for absolute certainty.

Product Type
Oil Pressure Switch (oil pressure sender)

Function
The oil pressure switch is a simple on/off switch that closes when oil pressure drops below a preset threshold (typically around 5–7 psi). When the switch closes, it completes the circuit and illuminates the oil pressure warning light on your dashboard, alerting you to low oil pressure.

Applications
This oil pressure switch fits Honda B-series (B16, B18, B20), D-series (D15, D16, D17), F-series (F20, F22, F23), and H-series (H22, H23) engines found in Civic (4th–7th gen), Accord (3rd–6th gen), Prelude (3rd–5th gen), CRX (2nd gen), Integra (2nd–3rd gen), and other models from approximately 1986 through 2006. It is not compatible with K-series engines.

FAQ

Is this a genuine Honda part or a copy?
This is 100% genuine Honda OEM — in original factory packaging with Honda part number printed on the label. It is not an aftermarket brand or a replica.

Does this fit my 1999 Honda Civic with the D16 engine?
Yes — the 6th generation Civic with D16 uses this oil pressure switch. We recommend verifying with your VIN.

What’s the difference between 35710-SE3-A01 and 35710-SE3-A02?
A02 is the superseded part number for some later production runs. Both switches are functionally identical and interchangeable. Check your original part number to confirm.

Does this switch work with an oil pressure gauge?
No — this is a simple on/off switch for the warning light only. If you have an oil pressure gauge, you need a different sender unit (typically a variable-resistance sender).

Will this fit my Honda CR-V with the K24 engine?
No — CR-V with K-series engines uses a different oil pressure switch (37240-PT0-014). Please check your original part number before ordering.

What is the torque spec for installation?
The recommended torque is typically 15–20 Nm (11–15 ft-lbs). Do not overtighten — the switch housing can crack.

Can I install this myself?
Yes — it is a simple one-bolt replacement. However, we recommend consulting your vehicle’s service manual for the correct installation procedure and torque specification.
