Code P2135 Suzuki Description

The P2135 Suzuki code indicates a problem with the Throttle/Pedal Position Sensor/Switch 'A'/'B' voltage correlation. This means that the voltage signals from the throttle position sensor (TPS) and the pedal position sensor (PPS) do not align as expected by the Engine Control Module (ECM). The TPS is responsible for monitoring the position of the throttle valve, while the PPS detects the position of the accelerator pedal. When these sensors do not correlate properly, it can lead to issues with engine performance, fuel efficiency, and overall drivability of the vehicle.
