What Does P3475 Mean?
The PCM has detected a low voltage condition in cylinder 10's intake valve deactivation control circuit. This electrical fault prevents proper solenoid operation for cylinder deactivation.
Common Causes
35%
Wiring harness short to ground in deactivation solenoid circuit
30%
Failed cylinder 10 intake valve deactivation solenoid with internal short
20%
Corroded or oil-contaminated connector causing reduced resistance
10%
PCM output driver failure pulling circuit low
5%
Damaged solenoid causing intermittent short to engine ground
Diagnostic Steps
1
Step 1: Visually inspect wiring and connector at cylinder 10 intake valve deactivation solenoid for damage or oil intrusion
2
Step 2: Disconnect solenoid connector and measure solenoid resistance; verify within specifications
3
Step 3: Check for voltage at solenoid connector with key on; should show battery voltage when activated
4
Step 4: Test circuit from PCM to solenoid for short to ground using ohmmeter with connector disconnected
5
Step 5: Verify PCM operation by commanding solenoid on/off with scan tool and monitoring voltage response
Estimated Repair Cost
$150 - $850
Parts + labor, varies by vehicle and location
The PCM has detected a low voltage condition in cylinder 10's intake valve deactivation control circuit. This electrical fault prevents proper solenoid operation for cylinder deactivation.
The most common cause of P3475 (Cylinder 10 Deactivation/Intake Valve Control Circuit Low) is: Wiring harness short to ground in deactivation solenoid circuit
Typical repair costs for P3475 range from $150 to $850, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive with no immediate safety concerns. Fuel economy will be reduced as cylinder deactivation is disabled.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P3475 to identify the root cause.
