What P27BE means
P27BE means the control circuit of solenoid N is electrically intact but behaves implausibly, for example a measured current that does not follow the command. No manufacturer documents P27BE publicly. GM's Corvette dual-clutch table 23OBDG07 does monitor exactly this for synchronizer valve 2, comparing target current with the current estimated from duty cycle and battery voltage, but files a deviation above 70 % for 60 ms or above 400 mA for 300 ms under P27C0 rather than here. Ford's TR9070 list also has no entry for it. CARB 13 CCR 1968.2 asks for a functional check of automatic transmission solenoids and, where none is feasible, at least circuit fault detection. Likely causes are a coil with drifting resistance, high connection resistance or a weak driver stage.
P27BE 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 P27BE
- MIL on
- Slow or incomplete gear engagement on one shift rod
Common causes of P27BE
- Most likelySolenoid N coil resistance out of specification
- PossibleHigh resistance at connector or crimp
- Less likelyUnstable supply voltage to the TCM
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P27BE 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. |
| BE | The exact fault in that area. |
What to do next
- Note P27BE 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 P27BE
What does P27BE mean?
P27BE means "Pressure Control Solenoid N Control Circuit Range/Performance". P27BE means the control circuit of solenoid N is electrically intact but behaves implausibly, for example a measured current that does not follow the command. It is a generic code, so it means the same on every make.
Is it safe to drive with P27BE?
Drive gently and only to a workshop. With P27BE the car can go into limp mode (reduced power) to protect itself.
Will P27BE fail an emissions test?
Yes, it can. P27BE 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 P27BE to fix?
Difficulty: medium. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P27BE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
