Key Notes:

• Part Numbers: 2380120, 3113857
• Weight: 0.28 lbs (0.13 kg)
• Type: Speed sensor
• Application: Speed sensor — monitors and transmits rotational speed data to the machine's electronic control system for accurate engine, transmission, or drivetrain speed monitoring across applicable Cat construction equipment platforms
• Note: 2380120 and 3113857 are confirmed interchangeable — confirm your machine model and the specific sensor location before ordering
• Condition: Aftermarket replacement part

Common Use Case or Symptoms: Use when the machine is displaying speed sensor fault codes, transmission shift points are erratic or non-responsive, ground speed readings are inaccurate or absent, or the ECM is reporting a speed sensor signal failure — a failed speed sensor causes loss of rotational speed data to the control system, triggering fault codes and disrupting speed-dependent functions on applicable Caterpillar equipment.
