What P2E67 means
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).

Symptoms of P2E67
- 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
Common causes of P2E67
- Most 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
- Less likelyWrong coolant or trapped air after service upsetting the temperature-based check
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E67 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 67 | The exact fault in that area. |
What to do next
- Note P2E67 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2E67
What does P2E67 mean?
P2E67 means "Engine Coolant Bypass Valve E Stuck Closed". P2E67 means valve E stays shut although the control asked it to open. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E67?
Drive gently and only to a workshop. With P2E67 the car can go into limp mode (reduced power) to protect itself.
Will P2E67 fail an emissions test?
Yes, it can. P2E67 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2E67 to fix?
Difficulty: medium. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P2E67 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
