What Does P2730 Mean?
The Transmission Control Module (TCM) has detected an abnormally high voltage in the control circuit for pressure control solenoid E. This typically indicates a short to voltage in the wiring or a failed solenoid.
Common Causes
35%
Short to voltage in pressure control solenoid E wiring harness
30%
Failed pressure control solenoid E with internal short
20%
Transmission control module (TCM) internal fault
10%
Corroded or damaged solenoid connector causing high resistance
5%
Chafed wiring creating intermittent short to power
Diagnostic Steps
1
Step 1: Visually inspect the pressure control solenoid E connector and wiring for damage, corrosion, or chafing
2
Step 2: Disconnect the solenoid E connector and measure resistance across solenoid terminals (typically 3-10 ohms)
3
Step 3: With connector disconnected, check for voltage on the TCM control wire (should be 0V with key on)
4
Step 4: If voltage is present at TCM connector with solenoid disconnected, repair short to voltage in harness
5
Step 5: If wiring checks good, replace pressure control solenoid E and retest
Estimated Repair Cost
$200 - $800
Parts + labor, varies by vehicle and location
The Transmission Control Module (TCM) has detected an abnormally high voltage in the control circuit for pressure control solenoid E. This typically indicates a short to voltage in the wiring or a failed solenoid.
The most common cause of P2730 (Pressure Control Solenoid "E" Control Circuit High) is: Short to voltage in pressure control solenoid E wiring harness
Typical repair costs for P2730 range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may experience harsh shifting, transmission slipping, or enter limp mode limiting speed. Safe to drive short distances to a repair facility but avoid highway speeds.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2730 to identify the root cause.
