Code P0501 Acura Description

The Continuously Variable Transmission (CVT) Speed Sensor is attached to the outside of the torque converter housing. The CVT Speed Sensor detects the number of revolutions of the secondary driven gear and sends a pulsing signal to the Powertrain Control Module (PCM). The PCM converts the pulsing signal into vehicle speed. If no pulses occur with the secondary driven gear rotating, the PCM detects a malfunction that may be caused by an open, an intermittent open, or a short to ground. Based on the correlation between the CVT Speed Sensor and the CVT drive pulley speed sensor, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
