B2113 RAM Code - 5 Volt Supply Circuit Low

Quick Answer

The B2113 diagnostic trouble code (DTC) refers to a 5 Volt Supply Circuit Low in the vehicle's system. Common causes include Faulty Sensor: A malfunctioning sensor that is connected to the 5-volt supply circuit can cause the voltage to drop below the normal range, Wiring or Connector Damage: Damaged or corroded wiring or connectors in the 5-volt supply circuit can disrupt the voltage flow, ECM Malfunction: A faulty engine control module (ECM) can also be a potential cause of the low voltage condition. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B2113 RAM Description

The B2113 diagnostic trouble code (DTC) refers to a 5 Volt Supply Circuit Low in the vehicle's system. This code indicates that the voltage on the 5-volt reference circuit is below the normal operating range. The 5-volt supply circuit is crucial for various sensors and components in the vehicle to function properly. When this circuit is not supplying the correct voltage, it can lead to issues with sensor readings, engine performance, and overall vehicle operation.

Common Causes of B2113 RAM

  1. Faulty Sensor: A malfunctioning sensor that is connected to the 5-volt supply circuit can cause the voltage to drop below the normal range.
  2. Wiring or Connector Damage: Damaged or corroded wiring or connectors in the 5-volt supply circuit can disrupt the voltage flow.
  3. ECM Malfunction: A faulty engine control module (ECM) can also be a potential cause of the low voltage condition.
  4. Short Circuit: A short circuit in the 5-volt supply circuit can cause the voltage to drop, triggering the B2113 code.

Symptoms of B2113 RAM

  1. Check Engine Light: The most common symptom associated with the B2113 code is the illumination of the check engine light on the vehicle's dashboard.
  2. Poor Engine Performance: The vehicle may experience rough idling, misfires, or a lack of power due to incorrect sensor readings.
  3. Stalling: The engine may stall unexpectedly while driving, especially at low speeds or when coming to a stop.
  4. Starting Issues: The vehicle may have difficulty starting or may not start at all due to the low voltage condition affecting critical systems.

How to Fix B2113 RAM

  1. Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble codes and perform a thorough inspection of the 5-volt supply circuit, sensors, wiring, and connectors.
  2. Test Sensors: Check the sensors connected to the 5-volt supply circuit to determine if any are faulty and need replacement.
  3. Inspect Wiring and Connectors: Inspect the wiring and connectors in the 5-volt supply circuit for any damage or corrosion. Repair or replace as needed.
  4. Check ECM: Test the engine control module (ECM) to ensure it is functioning correctly. Replace if necessary.
  5. Clear Codes and Test Drive: Clear the trouble codes from the ECM, and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix B2113 RAM

The typical repair costs for addressing a B2113 code can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, the cost of parts for sensor replacement, wiring repairs, or ECM replacement can range from $100 to $500. Labor costs at auto repair shops typically range from $80 to $150 per hour. The total cost of repairs for a B2113 code could range from $200 to $1000 or more, depending on the complexity of the repair and the rates charged by the repair shop. It is advisable to check with local auto repair shops for a more accurate estimate based on the specific make and model of the vehicle.
