FAQ

This oil pressure sensor switch is compatible with various Nissan and Infiniti vehicles, including the Nissan 350Z, Altima, Armada, Frontier, GT-R, Pathfinder, Sentra, Titan, and Xterra, as well as the Infiniti QX56. It is designed for use with Nissan 2.0L, 2.5L, 3.5L, 3.8L, 4.0L, and 5.6L engine applications. Because fitment can vary by engine and production date, please confirm compatibility by matching your original part number before ordering.
This part replaces OEM number 25070-CD00A and is compatible with PS417. It also serves as a direct replacement for part numbers 25070CD00A, 25070 CD00A, 25070-CD000, 25070CD000, 25070 CD000, 201-2368, 1S6896, and PS561.
Typical signs include an oil warning light that stays on or flickers, an oil pressure gauge reading that drops out or behaves erratically, or a warning appearing even when the engine has a proper oil level and no obvious mechanical noise. Some vehicles may also show oil seepage through the sensor body or connector area if the switch housing has failed.
On many Nissan and Infiniti applications, this is a moderate repair because the sensor is threaded into an engine oil passage and access can be tight. Basic installation involves disconnecting the electrical connector, removing the old sender with the correct deep socket or oil pressure switch socket, and threading in the replacement. Expect the process to take roughly 15 to 60 minutes depending on the specific engine layout and access.
First, verify the engine oil level and condition, and inspect the sensor connector and wiring for oil contamination, corrosion, or damage. If the oil light is on, it is recommended to confirm actual oil pressure with a mechanical gauge before assuming the sensor is the only problem. Low oil level, sludge, a weak oil pump, or internal engine wear can produce the same warning symptoms as a failed switch.
These switches often fail due to heat cycling, internal diaphragm wear, vibration, or oil leaking into the electrical portion of the sensor over time. Connector contamination and aged wiring can also cause false low-pressure warnings. On higher-mileage engines, sensor replacement is common, but it is important to rule out true low oil pressure before returning the vehicle to service.
