P214EReductant Pump A Current Too High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P214E means the electronics driving the DEF (AdBlue) pump motor saw more current than the pump may draw. GM documents it on Duramax diesels: in the 2018 tables the DEF control module reports a motor high-current or current-limit error, and the ECM sets the code after 20 failed of 25 samples with the battery above 11 V; the 2025 tables use a hardware protection limit of 15 A plus separate motor current limits for pumping and for heating mode, in which the pump is driven to warm frozen fluid. Both are Type A, so the MIL comes on after one trip. Ford's 2023 diesel summary sets P214E when the pump motor controller exceeds 15 A. GM bulletin 20-NA-039 traced P214E on the 2020 Silverado/Sierra 1500 3.0L to software. A seized or iced pump stops dosing; P2C11 is the low-current counterpart.
- What you may notice
- Check engine light on after one trip
- DEF system warning, possibly a countdown to speed limitation
- Raised NOx emissions because dosing stops
- Likely causes
- LikelyPump motor seized, worn or blocked by crystallised or frozen fluid
- PossibleShort in the pump motor winding or supply wiring, often after water ingress
- PossibleECM or reductant control module software (GM 20-NA-039)
- RareFaulty driver stage in the reductant control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
