Delphi SS11988 Engine Crankshaft Position Sensor

Delphi SS11988 Crankshaft Position Sensor

The Delphi SS11988 engine crankshaft position sensor is built for precise engine speed and crankshaft signal monitoring in a wide range of Nissan and INFINITI applications. With OE heritage behind the design, this black sensor uses a 3-terminal, female oval connector for a direct-fit style replacement.

It is a strong match for drivers searching for a crankshaft position sensor for Nissan Altima, Maxima, Murano, Pathfinder, 370Z, GT-R, and INFINITI Q50, QX50, QX60, Q60, and related models. The Delphi SS11988 is engineered with the same OE-focused knowledge that supports modern ignition and sensor performance.

Key Features

• Engine crankshaft position sensor for ignition and engine management systems
• Black housing with a 1-connector, oval female plug design
• 3-terminal male pin configuration
• Wiring harness not included
• Package contents: engine crankshaft position sensor and instruction sheet
• OE heritage from Delphi, a supplier to major automakers

Detailed Description

Delphi SS11988 is an OE-style crankshaft position sensor designed to report crankshaft position and engine speed data to the vehicle control system. Accurate signal input is critical for ignition timing, fuel delivery, and overall drivability, especially in Nissan and INFINITI vehicles that rely on consistent sensor feedback. This part number, SS11988, is commonly searched for replacement needs on models such as the Nissan Altima, Murano, Maxima, Pathfinder, 370Z, GT-R, and INFINITI Q50, QX50, QX60, and Q60.

This part cross-references DENSO Auto Parts 196-4009 for the same application. It also cross-references Standard Ignition PC791 for the same application.

Common Issues This Sensor May Address

• Crank/no-start condition caused by a failed crankshaft signal
• Intermittent stalling or rough running from inconsistent engine speed input
• Check engine light related to crankshaft position sensor faults
• Hard starting after heat soak or during cold starts
• Misfire or timing-related drivability concerns tied to sensor signal loss

Installation Notes and Tips

Before installation, compare the connector shape, terminal count, and sensor location to the original part. The Delphi SS11988 uses a female oval connector with 3 terminals and does not include a wiring harness. Follow the instruction sheet included in the package and inspect the connector for corrosion, bent pins, or damaged locking tabs before reconnecting.
