Detailed Description

The Delphi SS12171 is an engine crankshaft position sensor engineered for Nissan vehicles that rely on precise crankshaft timing data. It is used in applications such as 2005-2017 Nissan Frontier, 2005-2015 Nissan Xterra, 2005-2012 Nissan Pathfinder, and 2012-2021 Nissan NV1500, NV2500, and NV3500. For 2018 Nissan Frontier applications, this part applies to vehicles built to 09/2017. If you are searching for a Nissan Frontier crankshaft position sensor, Nissan Xterra crank sensor, or Nissan Pathfinder engine speed sensor, this part number is a direct match for the listed applications.

Delphi draws on more than a century of OE experience, and that background is built into the aftermarket design of this sensor. The SS12171 is intended to restore accurate crankshaft signal delivery to the engine control system, helping maintain proper ignition timing and engine operation. This part number also cross-references Spectra Premium S10277 for the same application.

What It Helps Address

• Hard starting or extended crank time caused by a weak crankshaft signal
• Intermittent stalling related to crankshaft position signal loss
• Check engine light conditions tied to crank sensor faults
• Rough running or misfire symptoms from incorrect engine timing input
• No-start conditions when the engine control module cannot read crankshaft position

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle application before installation. This sensor uses a single oval female connector with 3 terminals and does not include a wiring harness. Compare the original part number and connector style on your Nissan Frontier, Xterra, Pathfinder, or NV-series vehicle before replacement. Follow the included instruction sheet and inspect the connector and harness for damage during service.

Quality Assurance

Delphi builds this sensor using OE-focused engineering informed by long-term supplier experience with major automakers. The SS12171 is made to meet the needs of the listed Nissan applications with a direct-fit design and application-specific connector configuration.
