Code P2135 2008 Nissan Altima Sedan Description

The P2135 diagnostic trouble code (DTC) for a 2008 Nissan Altima Sedan refers to the Throttle Position Sensor Circuit Range/Performance. This code indicates that the Engine Control Module (ECM) has detected a discrepancy in the signal voltage between the throttle position sensor (TPS) and the accelerator pedal position sensor (APP). The TPS is responsible for monitoring the position of the throttle valve and sending this information to the ECM, which then adjusts the air-fuel mixture for optimal engine performance. The APP sensor, on the other hand, detects how much the accelerator pedal is pressed and relays this data to the ECM to control the throttle opening.
