Rocker Arm Oil Pressure Switch Honda Fit 1.5L 2008-2013 Location

Exact Component Location

This video focuses exclusively on showing you the exact, precise location of the VTEC Oil Pressure Switch on the 1.5L L15A7 engine (2008–2013 Honda Fit).

If you are trying to find it, look at the passenger (right) side of the cylinder head, right next to the VTEC Solenoid assembly you previously identified. The pressure switch is a small, threaded sensor with a single-wire electrical connector, screwed directly into the side of the VTEC solenoid housing or the cylinder head casting immediately adjacent to it. It is distinct from the solenoid itself—while the solenoid has a larger connector for the valve operation, the switch is smaller and specifically monitors hydraulic pressure to confirm that the VTEC system has engaged.

How This Video Helps Your DIY Repair

Locating this switch quickly is the crucial first step for troubleshooting VTEC-related performance issues. By seeing the exact spot and identifying how the wiring harness tucks in near the valve cover gasket and the engine lifting eye, you can easily plan your approach. This visual guide shows you exactly which angle to use for your deep-well socket to avoid interfering with the cooling lines or engine mount, saving you valuable time and letting you proceed with confidence.

Symptoms of a Faulty Oil Pressure Switch

A failing or faulty pressure switch sends incorrect information to the Engine Control Module (ECM). Common symptoms include:

• Check Engine Light (CEL): Most commonly triggers P2646 or P2647 codes.
• VTEC System Disengagement: If the switch fails to report the correct pressure, the computer will refuse to engage the high-output cam profile, leading to a noticeable drop in power.
• Limp Mode: Similar to a faulty solenoid, a bad switch can trigger a high-RPM restriction.
• Oil Seepage: Like other sensors in this area, the rubber O-ring seal behind the switch can degrade, causing a small, annoying oil drip down the side of the cylinder head.

Safety Measures and Precautions

Before beginning, prioritize safety. Always wear proper protective gear, including safety glasses and mechanic gloves, to protect against oil exposure and sharp engine castings.

Critical Safety Note: The switch is threaded into an aluminum housing. Do not over-tighten it when installing the replacement, as you can easily strip the aluminum threads. Simply tighten it until the crush washer seats and it is snug. Additionally, be very careful when removing the electrical connector; the plastic locking tab is prone to snapping in cold weather, so use a small pick tool to gently lift the tab before pulling.
