What P2017 usually means
P2017 is the high-signal counterpart to P2016. The PCM sees the Bank 1 runner feedback voltage or switch state higher than expected, which usually points to a signal shorted toward voltage, a biased sensor, unstable ground, or a runner assembly that is not where the PCM thinks it should be. The important diagnostic move is to compare the high reading with actual runner motion before deciding the actuator or manifold has failed.
