What P2759 means
P2759 is a general electrical fault on the control circuit of the converter clutch pressure solenoid, used where a module cannot distinguish an open from a ground or supply short. No manufacturer documents P2759 publicly. The principle is visible in Ford's 2012 summary: the TCC output is pulse-width driven and a feedback line from the driver reveals opens and shorts, while makers such as GM report each case separately under P2761, P2763 and P2764. CARB requires this circuit check for transmission outputs. A meter test of coil resistance and of each wire to ground and to battery usually narrows it down quickly. Until repaired, many controllers inhibit lockup, so cruise rpm and fluid temperature rise slightly.
P2759 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2759
- No converter lockup
- Slightly higher fuel consumption
- Warning lamp on
Common causes of P2759
- Most likelyDamaged wire or connector between TCM and solenoid
- PossibleSolenoid coil open or shorted
- Less likelyFaulty TCM output driver
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2759 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. |
| 59 | The exact fault in that area. |
What to do next
- Note P2759 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 P2759
What does P2759 mean?
P2759 means "Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical". P2759 is a general electrical fault on the control circuit of the converter clutch pressure solenoid, used where a module cannot distinguish an open from a ground or supply short. It is a generic code, so it means the same on every make.
Is it safe to drive with P2759?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2759 fail an emissions test?
Yes, it can. P2759 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 P2759 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2759 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
