P27CE code meaning
Pressure Control Solenoid R Control Circuit Range/Performance
Powertrain system Generic code P27xx codes Check engine light
What P27CE means
P27CE would be stored if the control circuit of solenoid R stayed electrically connected yet produced values that make no sense to the controller. No manufacturer documents this code publicly. On the Corvette dual-clutch transmission GM checks valve 4 for a mismatch between commanded and estimated current (over 70 % for 60 ms, or 400 mA for 300 ms in 23OBDG07), but that check reports P27D0. Ford's 2024 list for the TR9070 likewise offers only open load, shorted load and shorted switch for SPV4. CARB 13 CCR 1968.2 sets the general monitoring duty. Typical reasons would be rising contact resistance, a solenoid with partly shorted turns, or a weak TCM driver output.
P27CE at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor1 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P27CE
- MIL on
- Shift feel varies on rods 3 and 4
Common causes of P27CE
- Most likelyRising contact resistance in the circuit
- PossibleSolenoid R with partly shorted turns
- Less likelyWeak TCM driver output
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P27CE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| CE | The exact fault in that area. |
What to do next
- Note P27CE 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 P27CE
What does P27CE mean?
P27CE means "Pressure Control Solenoid R Control Circuit Range/Performance". P27CE would be stored if the control circuit of solenoid R stayed electrically connected yet produced values that make no sense to the controller. It is a generic code, so it means the same on every make.
Is it safe to drive with P27CE?
Drive gently and only to a workshop. With P27CE the car can go into limp mode (reduced power) to protect itself.
Will P27CE fail an emissions test?
Yes, it can. P27CE 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 P27CE to fix?
Difficulty: medium. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P27CE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
