What P2737 means
The standard title describes implausible readings on the control circuit of solenoid F that are neither a clean open nor a short. GM's 2025 table 25OBDG03A fills the code with a hydraulic test on its CVT, where valve F switches the binary oil pump between half and full capacity. With the vehicle below 2 mph, accelerator released, engine between 600 and 1,200 rpm, fluid above 50 °C and the garage shift finished, the TCM compares the averaged pressures from the primary and secondary pulley sensors in both pump modes. If the differences stay too large, the valve is judged not to follow its command; GM classes this Type B, so the MIL comes on after two trips. Other makers do not publish P2737. A failed pump valve can reduce clamping pressure and lead to belt slip.

Symptoms of P2737
- MIL on after two trips
- Belt slip, flare or reduced power
- Whine from the CVT
Common causes of P2737
- Most likelyBinary pump control valve sticking (GM CVT)
- PossiblePrimary or secondary pulley pressure sensor reading wrong
- PossibleLow or degraded CVT fluid
- Less likelyHigh resistance in the solenoid F circuit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2737 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. |
| 37 | The exact fault in that area. |
What to do next
- Note P2737 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 P2737
What does P2737 mean?
P2737 means "Pressure Control Solenoid F Control Circuit Range/Performance". The standard title describes implausible readings on the control circuit of solenoid F that are neither a clean open nor a short. It is a generic code, so it means the same on every make.
Is it safe to drive with P2737?
Drive gently and only to a workshop. With P2737 the car can go into limp mode (reduced power) to protect itself.
Will P2737 fail an emissions test?
Yes, it can. P2737 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 P2737 to fix?
Difficulty: workshop only. A typical repair takes 1 to 12 hours of work. This is a job for a workshop.
Will P2737 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.
