Common Diagnostic Steps

OBD2 Code: P1467

Description: EVAP Canister Purge Solenoid Valve Short Circuit to B

• Check the vehicle’s battery voltage and ensure it is within the specified range.
• Inspect the EVAP canister purge solenoid valve for any visible signs of damage or corrosion.
• Examine the wiring harness and connectors leading to the purge solenoid for any signs of wear, damage, or disconnection.
• Use a multimeter to test for continuity in the circuit between the ECM (Engine Control Module) and the purge solenoid valve.
• Verify that there is no short circuit by checking resistance values against manufacturer specifications.
• If necessary, replace any damaged components such as wires, connectors, or the purge solenoid itself.
• Clear the code using an OBD2 scanner and perform a road test to ensure that it does not return.
