What Does P3417 Mean?
The PCM has detected an open circuit in the intake valve control system for cylinder 3. There is no electrical continuity in the circuit, preventing proper intake valve timing or cylinder deactivation control.
Common Causes
35%
Disconnected or loose electrical connector at cylinder 3 intake valve control solenoid
30%
Broken wire in harness between PCM and cylinder 3 intake valve solenoid
25%
Failed intake valve control solenoid with open internal coil
8%
Corroded or damaged connector terminals causing loss of continuity
2%
PCM connector terminal issue or internal PCM fault
Diagnostic Steps
1
Step 1: Inspect cylinder 3 intake valve control solenoid connector for proper connection and secure engagement
2
Step 2: Disconnect solenoid and measure resistance across terminals; should read 6-12 ohms (infinite resistance indicates open coil)
3
Step 3: Test for continuity between PCM connector and solenoid connector on both power and ground circuits
4
Step 4: Inspect entire wiring harness for breaks, cuts, or damage, especially in areas subject to heat or movement
5
Step 5: Verify PCM connector terminals are not pushed back or damaged and making proper contact
Estimated Repair Cost
$120 - $750
Parts + labor, varies by vehicle and location
The PCM has detected an open circuit in the intake valve control system for cylinder 3. There is no electrical continuity in the circuit, preventing proper intake valve timing or cylinder deactivation control.
The most common cause of P3417 (Cylinder 3 Deactivation/Intake Valve Control Circuit/Open) is: Disconnected or loose electrical connector at cylinder 3 intake valve control solenoid
Typical repair costs for P3417 range from $120 to $750, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but may experience reduced power, rough idle, and poor fuel economy. Address soon to prevent potential engine damage from improper valve timing.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P3417 to identify the root cause.
