Standard Ignition ALS100 Vehicle Speed Sensor

Vehicle Speed Sensor for Dodge Ram and Dakota

Standard Ignition ALS100 is a vehicle speed sensor built for direct-fit service on select Dodge trucks and SUVs. It uses a sealed design, insulated copper windings, and a magnetic circuit engineered to deliver a steady output signal across changing driving conditions.

Key Features

• External and internal nitrile rubber oil seal for a secure, leak-resistant fit
• High-temperature insulated copper windings for durability in demanding heat
• Magnetic circuit design for consistent signal output
• 100% end-of-line tested for signal amplitude and frequency
• Female 3-pin rectangular connector with 4-inch harness
• Mounts at the spindle with a single bolt hole

Detailed Description

Standard Ignition ALS100 is a replacement vehicle speed sensor for applications that rely on accurate wheel or drivetrain speed input for transmission control, speedometer operation, and related electronic functions. The sealed construction helps maintain a secure connection at the mounting point, while the insulated copper windings and magnetic circuit support stable performance in harsh underbody conditions. This part number, ALS100, is listed for select 1998-2001 Dodge Ram 1500, 1998-2001 Dodge Ram 2500, 1998-1999 Dodge Ram 3500, 1998 Dodge Dakota, and related Dodge applications with harnessed rear-axle or steering-column configurations. This part cross-references Dorman - OE Solutions 970-024 for the same application.

What It Helps Fix

• Erratic or inoperative speedometer readings
• Transmission shift concerns tied to missing vehicle speed input
• ABS or drivetrain signal faults caused by a failing sensor
• Intermittent speed signal loss from heat, vibration, or contamination
• Warning lights related to speed sensor circuit issues

Installation Notes and Tips

Verify the connector style, harness length, and mounting location before installation. ALS100 uses a female 3-terminal rectangular connector, a 4-inch harness, and a spindle-mounted, single-bolt design. Confirm the vehicle application carefully for 1998-2001 Dodge Ram 1500, 1998-2001 Dodge Ram 2500, 1998-1999 Dodge Ram 3500, 1998 Dodge Dakota, and other listed Dodge models, since fitment varies by year and configuration. For best results, inspect the mating connector and wiring for corrosion or damage before connecting the new sensor.

Quality Assurance

Standard Ignition subjects ALS100 to 100% end-of-line testing to confirm proper signal amplitude and frequency before release. The design also incorporates sealed nitrile rubber protection and high-temperature insulated windings to support reliable operation in automotive service.
