• Specifiion

• Function

1. Primary Function: Measure and Transmit Vehicle Speed
The fundamental purpose of the 21E3-0042 Speed Sensor is to detect the rotational speed of a rotating component linked to the vehicle’s drivetrain (typically the output shaft of the transmission, differential, or wheel hub) and convert this mechanical rotation into an electrical signal. This electrical signal (analog or digital, depending on the vehicle model) is then sent to the vehicle’s Engine Control Module (ECM) or Transmission Control Module (TCM)—the "brain" of the vehicle’s powertrain.

2. Key Roles in Onboard Systems
The speed data from 21E3-0042 is not just for the speedometer; it enables the proper operation of multiple critical vehicle systems:
Speedometer/Tachometer Display: The most visible role—converts the sensor’s electrical signal into a readable speed on the instrument cluster, so the driver knows the vehicle’s current speed.
Transmission Shifting (Automatic Transmissions): The TCM uses speed data to determine optimal shift points (e.g., when to shift from 1st to 2nd gear or downshift during braking). Without accurate speed input, shifts may be delayed, harsh, or incorrect.
