What Does P1723 Mean?
The shift solenoid driver (SSD) inductive signature is abnormal, indicating a problem with the transmission solenoid's electromagnetic characteristics. This suggests internal solenoid failure or circuit problems affecting shift quality.
Common Causes
45%
Failed transmission shift solenoid with abnormal coil resistance
25%
Internal transmission wiring harness fault or short circuit
15%
Low transmission fluid causing solenoid overheating
15%
Transmission control module driver circuit failure
Diagnostic Steps
1
Step 1: Check transmission fluid level and condition for proper fill and contamination
2
Step 2: Access transmission solenoid pack and measure resistance of each solenoid coil
3
Step 3: Perform inductive signature test using oscilloscope to analyze solenoid waveform patterns
4
Step 4: Inspect internal transmission harness connector for damage, corrosion, or burnt pins
5
Step 5: If solenoids test within specification, monitor TCM driver circuits with lab scope during operation
Estimated Repair Cost
$250 - $1,200
Parts + labor, varies by vehicle and location
The shift solenoid driver (SSD) inductive signature is abnormal, indicating a problem with the transmission solenoid's electromagnetic characteristics. This suggests internal solenoid failure or circuit problems affecting shift quality.
The most common cause of P1723 (SSD Inductive Signature Malfunction) is: Failed transmission shift solenoid with abnormal coil resistance
Typical repair costs for P1723 range from $250 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Can cause harsh shifts, transmission slipping, or failure to shift properly, potentially leading to loss of power or unexpected gear engagement. May cause transmission to enter limp mode.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1723 to identify the root cause.
