Detailed Description

The SC59 is a vehicle speed sensor for Nissan models that require a bolt-mounted, plug-in electrical connection. It is listed for 1993-1994 Nissan Altima, 1991-1992 Nissan NX, and 1991-1992 Nissan Sentra, making it a focused replacement for common speed signal service needs on these vehicles.

What It Helps Solve

• Erratic or missing vehicle speed signal
• Speedometer operation problems tied to the sensor circuit
• Connector wear or terminal damage at the sensor
• Mounting issues from a failed bolt-mount sensor
• Electrical faults related to a degraded 2-wire speed sensor
