What Does P2727 Mean?
The TCM cannot complete the control circuit for pressure control solenoid E, detecting an open circuit condition. This indicates a break in the wiring, disconnected connector, or complete solenoid failure preventing current flow.
Common Causes
35%
Open circuit in wiring harness between TCM and solenoid
30%
Disconnected or severely corroded connector
25%
Failed solenoid with open coil windings
7%
Blown fuse or fusible link in solenoid power circuit
3%
TCM connector terminal pushed out or damaged
Diagnostic Steps
1
Step 1: Check all fuses related to transmission control system
2
Step 2: Verify solenoid E connector is fully seated and locked; inspect for damaged terminals
3
Step 3: Measure resistance of solenoid E; infinite resistance indicates open coil
4
Step 4: Perform continuity test from TCM connector to solenoid connector on both wires
5
Step 5: Inspect wiring harness for physical damage, cuts, or areas where wire may be broken internally
Estimated Repair Cost
$150 - $900
Parts + labor, varies by vehicle and location
The TCM cannot complete the control circuit for pressure control solenoid E, detecting an open circuit condition. This indicates a break in the wiring, disconnected connector, or complete solenoid failure preventing current flow.
The most common cause of P2727 (Pressure Control Solenoid "E" Control Circuit/Open) is: Open circuit in wiring harness between TCM and solenoid
Typical repair costs for P2727 range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Transmission will likely enter limp mode with reduced functionality. May be stuck in one gear or have limited gear range.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2727 to identify the root cause.
