Engine 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 Engine Oil Pressure Switch (often called the Oil Pressure Sender) on the 1.5L L15A7 engine (2008–2013 Honda Fit).

Do not confuse this with the VTEC oil pressure switch mentioned previously. To find the engine’s main oil pressure switch, look at the rear (firewall side) of the engine block, on the passenger side. It is threaded directly into the engine block casting, located just above the oil filter mounting area and behind the serpentine belt drive assembly. It is a small, single-pin sensor with a single wire boot (usually black or rubberized) attached to it.

How This Video Helps Your DIY Repair

Locating this switch is the crucial first step for fixing a “low oil pressure” warning light or a stubborn oil leak. Because this area is very tight, tucked behind the alternator and the engine bracketry, this visual guide shows you exactly which route to take—often from underneath the vehicle—to reach the sensor with your deep-well socket. This prevents you from struggling blindly or accidentally damaging surrounding components.

Symptoms of a Faulty Oil Pressure Switch

When this switch fails, it can provide misleading information to the dashboard, potentially masking a real mechanical problem or causing unnecessary panic. Common symptoms include:

• Flickering or Constant “Oil Can” Light: The oil light on your dash stays on even when the engine has plenty of oil, or it flickers inconsistently.
• External Oil Leak: The internal diaphragm of the switch can rupture, causing oil to leak through the center of the sensor and down the side of the engine block, often creating a burning oil smell.
• False Readings: The gauge (if equipped) or warning system reports incorrect pressure despite the engine running smoothly.

Safety Measures and Precautions

Before beginning, prioritize safety. Always wear proper protective gear, including safety glasses and mechanic gloves, to protect your skin from hot engine oil and sharp underbody edges.

Critical Safety Note: Even if the oil light is on, always verify your actual oil level with the dipstick before assuming the switch is the problem. If the light is on and your oil is critically low, do not run the engine. When removing the switch, be prepared for a small amount of oil to drain out as soon as the sensor is unthreaded—have a shop rag or a catch-pan ready to keep your driveway and the engine’s serpentine belt clean.
