Code No. P0459: Purge Control Solenoid Valve Circuit High Input
 
 
 
 
OPERATION
  • Power is supplied to the purge control solenoid valve from the engine control relay.
  • The engine-ECU connector terminal PURG makes the power transistor in the unit be in ON position, and that makes currents go on the purge control solenoid valve.
 
 
FUNCTION
  • In response to a signal from the engine-ECU, the purge control solenoid valve controls the flow rate of the purge air to be introduced into the inlet manifold.
 
 
TROUBLE JUDGEMENT
Check Conditions
  • Engine is running.
  • Battery positive voltage is more than 10 V and is less than 16.5 V.
Judgement Criterion
  • The coil current is more than 2.3 A with the purge control solenoid valve driving.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • None
 
 
PROBABLE CAUSES
  • Failed purge control solenoid valve
  • Short circuit to power supply in purge control solenoid value control line
  • Damaged purge control solenoid valve connector
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE actuator test
  • Item 4: Purge control solenoid valve ON
OK: Operating sound can be heard and the valve vibrates
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Go to Step 2.
 
STEP 2. Perform resistance measurement at purge control solenoid valve connector.
  • Disconnect connector, and measure at solenoid valve side.
  • Resistance between terminals.
OK: 21 - 27 Ω (at 20°C)
Is the check result normal?
Go to Step 3.
Replace the purge control solenoid valve.
 
STEP 3. Check of short to power supply in PURG between purge control solenoid valve connector and engine-ECU connector.
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness.
 
STEP 4. M.U.T.-IIISE actuator test

Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Replace the engine-ECU.
