P2759Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
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.
What you may notice
  • No converter lockup
  • Slightly higher fuel consumption
  • Warning lamp on
Likely causes
  • LikelyDamaged wire or connector between TCM and solenoid
  • PossibleSolenoid coil open or shorted
  • RareFaulty TCM output driver
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
