What Does P3469 Mean?
The PCM has detected an open circuit in the cylinder 9 exhaust valve control circuit, indicating complete loss of electrical continuity. The system cannot control exhaust valve timing or deactivation for cylinder 9.
Common Causes
35%
Broken or severed wire in exhaust valve control circuit
30%
Failed exhaust valve control solenoid with internal open circuit
20%
Disconnected or heavily corroded electrical connector
10%
Wire damaged by heat exposure near exhaust components
5%
PCM connector terminal damage or pin push-back
Diagnostic Steps
1
Step 1: Visually inspect exhaust valve control solenoid connector and wiring for obvious damage, disconnection, or corrosion
2
Step 2: Disconnect solenoid and measure resistance across solenoid terminals; infinite resistance indicates open solenoid
3
Step 3: Test continuity from PCM connector to solenoid connector on both control and ground circuits
4
Step 4: Perform wiggle test on wiring harness while monitoring resistance to locate intermittent open connections
5
Step 5: Inspect PCM connector for bent pins, corrosion, or terminal push-out; repair connector if necessary
Estimated Repair Cost
$120 - $800
Parts + labor, varies by vehicle and location
The PCM has detected an open circuit in the cylinder 9 exhaust valve control circuit, indicating complete loss of electrical continuity. The system cannot control exhaust valve timing or deactivation for cylinder 9.
The most common cause of P3469 (Cylinder 9 Exhaust Valve Control Circuit/Open) is: Broken or severed wire in exhaust valve control circuit
Typical repair costs for P3469 range from $120 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Cylinder 9 exhaust valve timing will be fixed in default position, potentially causing reduced power, poor fuel economy, or rough running. Safe to drive short distances but repair soon to avoid potential engine damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P3469 to identify the root cause.
