P303A: Unraveling The Mystery Of Misfire In Cylinder 3
The P303A code is related to the voltage sensor circuit performance of the HybridEV Battery Interface Control Module 11.
The hybrid battery contains 192 individual cells, which are electrically connected in series to form 3 distinct sections.
The battery energy control module monitors the voltage of the 96 battery cell groups through voltage sense lines attached to each individual cell group. The battery energy control module contains internal interface control modules that monitor specific cell groups and communicate diagnostics and system status to the hybrid powertrain control module 2. The P303A code indicates a fault condition in the voltage sensor circuit of the HybridEV Battery Interface Control Module 11, which is detected by the battery energy control module and communicated to the hybrid powertrain control module 2.
