P0ED0Hybrid/EV Battery F Voltage
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0ED0 is the general voltage code of hybrid/EV battery F, the sixth and last unit in this letter series. It reports an implausible voltage of the unit without separating unstable (P0ED1), low (P0ED2) and high (P0ED3) readings. Only storage systems divided into six or more separately monitored units can produce it, and no manufacturer documents P0ED0 publicly. Ford's 2019 hybrid BECM is an example of finely divided monitoring: it supervises the cells in groups of six per sense circuit and fails a circuit when any cell reads above 5 V or below 1 V for 11 seconds. CARB demands that the cells and voltage sensors of the energy storage are monitored with codes for the smallest replaceable unit. A battery warning and reduced power follow.
