P261ACoolant Pump B Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P261A reports an open circuit in the drive of an auxiliary electric coolant pump labelled B. Ford's gasoline OBD summaries for 2020-2023 and 2024 define pump B as the high-temperature loop pump for component cooling and check it continuously over 5 s with at least 11 V on board. Ford's EcoSport 1.0 EcoBoost of 2018 (SSM 47359) set P261A because connector C1450 at that pump could not latch fully; a pigtail kit cures it. Audi bulletin 2043142 for 2012-2016 2.0 TFSI engines (CAE, CPM) links P261A to P261C to a failing after-run circulation pump and fits an updated pump. VW's 2014 Touareg book flags it at 4.8-5.3 V on the line. P261C/P261D are the shorts, P261B the performance fault.
