What Does P1910 Mean?
Pressure Control Solenoid C has an intermittent short circuit condition. This solenoid regulates hydraulic pressure for specific clutch packs or bands, and intermittent electrical faults cause erratic transmission operation.
Common Causes
30%
Damaged or frayed wiring harness inside transmission causing intermittent shorts
25%
Failed pressure control solenoid C with internal short
20%
Contaminated transmission fluid causing solenoid electrical malfunction
15%
Loose or corroded connector at transmission valve body
10%
TCM internal driver circuit failure causing intermittent signal
Diagnostic Steps
1
Step 1: Monitor live data for pressure control solenoid C command vs actual values during test drive to identify when intermittent occurs
2
Step 2: Check transmission fluid condition and level; contaminated fluid can cause solenoid electrical issues
3
Step 3: Remove transmission pan and inspect internal wiring harness and connector for damage, fluid contamination, or loose connections
4
Step 4: Measure resistance and perform insulation resistance test on pressure control solenoid C
5
Step 5: Test TCM solenoid driver circuit output with oscilloscope for voltage spikes or irregular patterns
Estimated Repair Cost
$300 - $1,200
Parts + labor, varies by vehicle and location
Pressure Control Solenoid C has an intermittent short circuit condition. This solenoid regulates hydraulic pressure for specific clutch packs or bands, and intermittent electrical faults cause erratic transmission operation.
The most common cause of P1910 (Pressure Control Solenoid "C" Intermittent Short) is: Damaged or frayed wiring harness inside transmission causing intermittent shorts
Typical repair costs for P1910 range from $300 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Intermittent solenoid faults can cause unexpected gear changes, harsh shifts, or sudden loss of drive power. Vehicle may enter limp mode unexpectedly during operation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1910 to identify the root cause.
