P2E67Engine Coolant Bypass Valve E Stuck Closed
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2E67 means valve E stays shut although the control asked it to open. No manufacturer documents valve E publicly. GM's closed-side test on block valve D (P26C2) shows the pattern: a gap of more than 5° between commanded and measured angle while the raw feedback stays below 50°, 4 of 5 seconds, Type B in the 2025 table 25OBDG03B; the test pauses during end-stop learning. Ford patents describe temperature-based checks instead: valves are closed one at a time and the coolant temperature reaction is compared with the expected one, and a transmission warm-up valve counts as stuck closed when the fluid fails to warm as expected after the open command. A closed valve can be harmless (heater path) or serious (block or radiator path, risk of hot spots).
- What you may notice
- Check engine light
- Little or no heat from the heater, or rising engine temperature, depending on the circuit
- Possible reduced engine power to protect the engine
- Likely causes
- LikelyValve jammed closed by deposits, debris or swollen seals
- PossibleActuator motor or gearing unable to open the valve
- PossiblePosition feedback stuck at the closed value
- RareWrong coolant or trapped air after service upsetting the temperature-based check
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
