Code P2135 Acura Description

The P2135 code for Acura vehicles indicates a problem with the Throttle Position Sensor (TPS) 'A'/'B' voltage correlation. The TPS is a vital component of the electronic throttle control system, which communicates the position of the throttle pedal to the engine control module (ECM). When the ECM detects that the voltage signals from TPS 'A' and TPS 'B' do not correlate correctly, it triggers the P2135 code. This discrepancy can lead to various issues with the vehicle's performance and drivability.
