A P2115 trouble code indicates a voltage correlation problem between throttle or accelerator pedal position sensor “B” and other related sensors.
Modern vehicles use multiple sensors (A and B) to ensure accuracy and safety. The PCM constantly compares their signals. If the voltage readings don’t match within an expected range, it triggers this code.

This code is typically related to sensor signal mismatch or voltage inconsistency.
Yes — incorrect sensor correlation can cause unreliable throttle response and drivability issues. The vehicle may limit power to prevent unsafe operation.
This code requires careful electrical testing.
Proper diagnosis is key to avoid replacing unnecessary parts.
Yes, although less common. The PCM is responsible for comparing sensor signals. If it misinterprets or processes data incorrectly, it may trigger a P2115 code.
