Code B2059 Scion Description
The B2059 diagnostic trouble code (DTC) for Scion vehicles indicates a Vehicle Speed Malfunction. This code is typically triggered when the vehicle's onboard computer detects an issue with the speed sensor or related components that affect the vehicle's speed readings. The vehicle speed sensor is a crucial component that provides the engine control module (ECM) with real-time data on the vehicle's speed, which is essential for various systems such as the transmission, cruise control, and anti-lock braking system (ABS) to function properly.
Common Causes of B2059 Scion
- Faulty vehicle speed sensor.
- Damaged or corroded wiring/connectors related to the speed sensor.
- Issues with the ECM or related control modules.
- Mechanical damage to the speed sensor due to debris or road hazards.
- Incorrect tire size or tire pressure affecting speed sensor readings.
Symptoms of B2059 Scion
- Inaccurate speedometer readings or erratic speedometer behavior.
- Cruise control not engaging or maintaining speed properly.
- ABS warning light illuminated on the dashboard.
- Transmission shifting erratically or harshly.
- Engine stalling or hesitation during acceleration.
How to Fix B2059 Scion
- Begin by diagnosing the issue using a scan tool to retrieve the specific DTC and verify the vehicle speed sensor's operation.
- Inspect the wiring harness and connectors for any damage, corrosion, or loose connections. Repair or replace as necessary.
- Test the vehicle speed sensor's output signal using a multimeter to ensure it is within the manufacturer's specifications.
- If the speed sensor is faulty, replace it with a new OEM or high-quality aftermarket sensor.
- Clear the DTC and perform a road test to confirm that the vehicle speed readings are accurate and that the symptoms have been resolved.
Cost to Fix B2059 Scion
The typical repair costs for a Vehicle Speed Malfunction can vary depending on the specific cause of the issue and the labor rates in your area. In general, replacing a faulty vehicle speed sensor can cost between $100 and $300, including parts and labor. Additional costs may apply if wiring repairs or ECM diagnostics are needed. It's recommended to consult with a trusted mechanic or dealership to get an accurate estimate based on your vehicle's make and model. Keep in mind that labor rates can range from $80 to $150 per hour, so it's advisable to inquire about rates before proceeding with the repair.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
