What Does P2739 Mean?
The TCM has detected abnormally high voltage in the Pressure Control Solenoid F control circuit. This typically indicates a short to voltage, open circuit, or solenoid driver failure in the TCM.
Common Causes
35%
Open circuit in wiring harness between TCM and pressure control solenoid F
30%
Internally open pressure control solenoid F coil preventing current flow
15%
Short to voltage (battery positive) in solenoid control circuit wiring
15%
Loose, corroded, or pushed-out connector pins causing intermittent open circuit
5%
Failed TCM with damaged driver circuit unable to pull control circuit low
Diagnostic Steps
1
Step 1: Inspect all connectors in solenoid F circuit for looseness, bent pins, or corrosion
2
Step 2: Disconnect solenoid F and measure coil resistance; infinite resistance indicates open coil
3
Step 3: With solenoid disconnected, check for battery voltage on control wire indicating short to power
4
Step 4: Perform continuity test from TCM connector to solenoid connector to identify open circuit in harness
5
Step 5: If wiring is intact and solenoid tests open, replace solenoid; if solenoid is good, test TCM driver output capability
Estimated Repair Cost
$150 - $1,200
Parts + labor, varies by vehicle and location
The TCM has detected abnormally high voltage in the Pressure Control Solenoid F control circuit. This typically indicates a short to voltage, open circuit, or solenoid driver failure in the TCM.
The most common cause of P2739 (Pressure Control Solenoid "F" Control Circuit High) is: Open circuit in wiring harness between TCM and pressure control solenoid F
Typical repair costs for P2739 range from $150 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause transmission to default to limp mode with reduced functionality. Vehicle may experience harsh shifts, limited gear selection, or unexpected transmission behavior affecting safe operation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2739 to identify the root cause.
