P2E62Engine Coolant Bypass Valve E Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- Coolant bypass valve E is the fifth electrically driven coolant valve in the SAE lettering; which coolant path it controls (heater, radiator, transmission, block) is up to the carmaker. P2E62 says the engine computer sees an open or otherwise faulty drive circuit. No manufacturer documents valve E publicly. Ford's 2020–2023 gasoline summary shows the usual logic for its valves A to D: a smart driver reports an output fault during continuous monitoring and the code sets after 5 s. Driver chips find a broken line by feeding small test currents and checking where the pin voltage settles, as an AMI Semiconductor patent describes. VW fixed P2681 entries on 2024 Atlas models with new engine software instead of parts, so check for updates. Shorts to ground or supply are P2E63 and P2E64.
- What you may notice
- Check engine light or service message
- Heating, warm-up or cooling behaves differently, depending on what valve E controls
- Valve stays in its de-energised default position
- Likely causes
- LikelyLoose, corroded or unplugged connector at the valve
- PossibleBroken wire in the drive or supply line
- PossibleOpen winding in the valve actuator motor or solenoid
- RareECM software fault or defective output stage
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €30 – €500
