What Does P1469 Mean?
The EVAP purge solenoid valve circuit is open, meaning there is no electrical continuity in the circuit. The ECM cannot energize the valve to control vapor purge operation.
Common Causes
35%
Open circuit in wiring harness between ECM and purge valve
30%
Failed purge solenoid valve with open internal coil
20%
Disconnected or severely corroded electrical connector
10%
Blown fuse in purge solenoid control circuit
5%
Failed ECM driver circuit for purge valve
Diagnostic Steps
1
Step 1: Visually inspect purge valve connector for proper connection and terminal condition
2
Step 2: Measure resistance across purge solenoid valve terminals (should be 20-40 ohms typically)
3
Step 3: Check for voltage supply at purge valve connector with key on (should have 12V on one terminal)
4
Step 4: Test continuity in wiring from ECM to purge valve connector on both power and ground circuits
5
Step 5: Check relevant fuses in power distribution center
Estimated Repair Cost
$100 - $400
Parts + labor, varies by vehicle and location
The EVAP purge solenoid valve circuit is open, meaning there is no electrical continuity in the circuit. The ECM cannot energize the valve to control vapor purge operation.
The most common cause of P1469 (EVAP Canister Purge Solenoid Valve Open Circuit) is: Open circuit in wiring harness between ECM and purge valve
Typical repair costs for P1469 range from $100 to $400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive with no immediate safety concerns. Will fail emissions testing and may cause slight fuel odor or rough idle.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1469 to identify the root cause.
