Delphi SS12222 Engine Crankshaft Position Sensor

Delphi SS12222 Crankshaft Position Sensor

The Delphi SS12222 engine crankshaft position sensor is built for precise engine speed and crank position signal input on select Nissan applications. It is a direct-fit ignition sensor for vehicles such as the Nissan Altima, Maxima, and Quest, with OE-based engineering informed by Delphi’s long history supplying automakers.

• Engine crankshaft position sensor for ignition system signal monitoring
• Black housing with 1 oval female connector
• 3 male terminals with pin-style terminal type
• Wiring harness not included
• Package contents: engine crankshaft position sensor and instruction sheet

Detailed Fitment and Function

Delphi SS12222 is an OE-style crankshaft position sensor that helps the engine control system read crankshaft position and engine speed data accurately. It fits 2004-2009 Nissan Quest, 2005-2006 Nissan Altima, 2004-2006 Nissan Maxima, and 2002-2004 Nissan Altima from 01/2004. This part number is also referenced as Delphi SS12222 for catalog and cross-reference lookup, and it cross-references Standard Ignition PC689 for the same application.

What This Sensor Helps Address

• Hard starting caused by an unreliable crankshaft position signal
• Intermittent stalling related to crank sensor signal loss
• Check engine light conditions tied to crankshaft position sensor faults
• Rough running or misfire symptoms linked to inaccurate engine speed input
• No-start concerns when the engine control module cannot read crank position correctly

Installation Notes and Tips

Verify connector shape, terminal count, and mounting location before installation. The Delphi SS12222 uses a single oval female connector with three male terminals, so matching the electrical connection is important for proper fitment. Inspect the harness connector for corrosion, bent terminals, or damaged locking tabs before installing the new sensor on your Nissan Altima, Maxima, or Quest.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and engineering knowledge developed through more than 100 years of original equipment experience. That background supports consistent sensor design and application-specific fitment for select Nissan crankshaft position sensor replacements.
