Delphi SS12278 Engine Camshaft Position Sensor

Delphi SS12278 Camshaft Position Sensor

The Delphi SS12278 engine camshaft position sensor provides OE-standard signal accuracy for supported Mazda applications. Built with a black housing, square connector, and 2 blade terminals, it is a direct-fit sensor for vehicles that rely on precise camshaft timing input.

Compatible with 2007-2015 Mazda CX-9 and 2009-2013 Mazda 6, this Delphi camshaft position sensor is a practical replacement when the original sensor is no longer delivering consistent readings. The SS12278 is tested and calibrated to OE standards to support accurate engine management data.

Key Features

• Delphi SS12278 engine camshaft position sensor
• Black sensor body with square connector shape
• 2 blade terminals, male connector and male terminal design
• OE-standard testing and calibration for accurate readings
• Package contents include the sensor and instruction sheet
• No wiring harness included

Detailed Description

Delphi develops vehicle sensors using OE-focused validation methods, and the SS12278 follows that approach for camshaft position monitoring. This sensor helps the engine control system track camshaft position data needed for ignition and fuel timing decisions. For Mazda CX-9 and Mazda 6 applications, the SS12278 offers a direct replacement option that matches the original electrical interface and connector style.

This part cross-references Standard Ignition PC773 for the same application. If you are searching for a Mazda CX-9 camshaft position sensor or a Mazda 6 camshaft position sensor, Delphi SS12278 is the part number to verify against your vehicle’s original sensor.

What It Helps Address

• Camshaft position signal loss or erratic sensor output
• Check engine light related to camshaft position monitoring
• Hard starting caused by incorrect timing input
• Rough running from inconsistent engine synchronization data
• Driveability issues tied to faulty camshaft sensor readings

Installation Notes and Tips

Confirm connector shape, terminal count, and sensor location before installation. The SS12278 uses a square connector with 2 male blade terminals and does not include a wiring harness. Compare the original part number and vehicle application before replacing the sensor on a Mazda CX-9 or Mazda 6.

Quality Assurance

Delphi sensors are validated to OE standards and calibrated for accurate readings, helping support reliable engine management performance and reducing repeat repairs.
