Detailed Description

Standard Ignition PPS278 is a body sensor replacement for rear park assist applications on the Mazda CX-30 and Mazda MX-30 EV. It is designed for vehicles that use a rear parking aid sensor to detect nearby objects and support the driver during low-speed maneuvering. The connector layout, oval housing shape, and blade-terminal interface help match the original sensor connection used in these applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

  • Parking aid warning messages related to a failed rear sensor
  • Inaccurate or intermittent object detection at the rear bumper
  • Sensor damage from impact, moisture intrusion, or road debris
  • Loss of park assist function on Mazda CX-30 and MX-30 EV models
  • Fault codes tied to the rear parking assist circuit

Installation Notes and Tips

Verify the connector shape, terminal count, and rear position before installation. Inspect the bumper harness and surrounding mounting area for corrosion, broken tabs, or impact damage that could affect sensor operation. After replacement, confirm proper park assist operation and clear any stored diagnostic trouble codes if required by the vehicle.

Quality Assurance

Standard Ignition is a recognized aftermarket source for electrical and body control components, including parking aid sensors. PPS278 is built to match the specified connector and terminal configuration for the listed Mazda applications.
