Code P2135 Acura Description

The Electronic Throttle Control System (ETCS) controls the throttle valve opening. The system includes the throttle actuator, the throttle valve, Throttle Position (TP) sensors A and B, the Accelerator Pedal Position (APP) sensor, and the Powertrain Control Module (PCM). The APP sensor is operated via the throttle cable to determine the accelerator opening value when the driver presses the accelerator pedal. The accelerator pedal opening value is converted to a signal in the APP sensor and transmitted to the PCM to compute the target position. The PCM then operates the throttle actuator to move the throttle valve to the target position. The actual throttle valve position is determined by TP sensor A (installed in the throttle body). The PCM compares the voltages and the throttle valve positions of TP sensor A and TP sensor B. If the difference of the voltages or the throttle valve positions is a certain value or less for a set time, the PCM detects a malfunction in the relationship between TP sensor A and TP sensor B, and stores a Diagnostic Trouble Code (DTC).
