What Does P2726 Mean?
The TCM is detecting intermittent electrical problems with pressure control solenoid E circuit. The fault occurs sporadically, making diagnosis more challenging as connections or components may work normally during testing.
Common Causes
35%
Intermittent wiring connection or chafed wire
30%
Loose or corroded connector terminals
20%
Solenoid with intermittent internal short or open
10%
Vibration-induced intermittent ground connection
5%
Temperature-sensitive TCM internal fault
Diagnostic Steps
1
Step 1: Wiggle test all wiring harnesses and connectors while monitoring solenoid circuit with scan tool
2
Step 2: Inspect connectors for loose terminals, corrosion, or poor contact; perform terminal pull test
3
Step 3: Check for chafed wires along transmission case and frame where harness may contact metal
4
Step 4: Monitor solenoid E resistance and voltage during test drive when fault is likely to occur
5
Step 5: Apply heat gun or freeze spray to solenoid and connectors to recreate temperature-related faults
Estimated Repair Cost
$150 - $1,000
Parts + labor, varies by vehicle and location
The TCM is detecting intermittent electrical problems with pressure control solenoid E circuit. The fault occurs sporadically, making diagnosis more challenging as connections or components may work normally during testing.
The most common cause of P2726 (Pressure Control Solenoid "E" Intermittent) is: Intermittent wiring connection or chafed wire
Typical repair costs for P2726 range from $150 to $1,000, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Unpredictable shifting behavior may occur intermittently. Vehicle may suddenly enter limp mode during operation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2726 to identify the root cause.
