What This Sensor Helps Address

• Erratic or inaccurate speedometer readings
• Vehicle speed signal loss to the transmission or control modules
• Intermittent speed-related warning lights
• Harsh or inconsistent shifting caused by incorrect speed input
• Driveability issues tied to faulty vehicle speed data

Installation Notes and Tips

Verify connector style, terminal count, and harness routing before installation. Compare the original sensor to Delphi SS12258 to confirm the same electrical connection and mounting style for your Ford Ranger, Explorer, Explorer Sport Trac, Explorer Sport, Mountaineer, or Aerostar application. Clean the mounting area and inspect the harness for damage before connecting the new sensor.
