What Does C1927 Mean?
The steering module has detected a short-to-battery condition in the VAPS solenoid actuator return circuit. A voltage source is feeding the return wire, corrupting the current feedback signal and preventing the module from accurately controlling solenoid operation.
Common Causes
40%
Chafed return wire contacting a power feed in the engine bay harness
25%
Internal solenoid fault with return winding shorted to a power terminal
25%
Contaminated connector bridging return to power pins
10%
Module internal current sense circuit fault
Diagnostic Steps
1
Step 1: Disconnect the solenoid and check for voltage on the return wire (key on). Voltage present confirms a wiring or connector short.
2
Step 2: Measure resistance from the return wire to B+ and adjacent power wires.
3
Step 3: Inspect the harness for chafing near the steering gear and engine.
4
Step 4: Check the connector for fluid contamination and corroded bridged terminals.
5
Step 5: Repair and verify proper current feedback values with the module.
Estimated Repair Cost
$100 - $600
Parts + labor, varies by vehicle and location
The steering module has detected a short-to-battery condition in the VAPS solenoid actuator return circuit. A voltage source is feeding the return wire, corrupting the current feedback signal and preventing the module from accurately controlling solenoid operation.
The most common cause of C1927 (VAPS Solenoid Actuator Return Circuit Short To Battery) is: Chafed return wire contacting a power feed in the engine bay harness
Typical repair costs for C1927 range from $100 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Corrupted return circuit feedback causes the module to lose accurate control of steering assist, potentially resulting in unpredictable steering effort changes while driving.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1927 to identify the root cause.
