CANISTER PURGE SOLENOID

Function

The evaporative gases produced in the fuel tank are absorbed by the activated charcoal in the 
carbon canister. As The purge control solenoid valve opens these gases are delivered to the 
intake manifold for combustion purposes. The purge control solenoid valve is controlled by the 
control unit. The control unit operates this valve during the time the lambda control loop is 
active.

Specifications

RESISTANCE:

± 50 ohms

resistance:

12 Volts

supply voltage:

current:

± 250 mA

Electrical control

 

Most solenoids are normally closed. This means 
that the connection between the canister and the 
intake manifold is closed. The solenoid has a 
connector with two terminals. On one of those 
terminals is connected to the battery voltage. 
This supply-voltage is often switched with a 
relay. The other terminal leads directly to the 
control unit. The current through the solenoid is 
switched on during the time the control unit 
connects this terminal to ground. The voltage on 
this terminal is during this time 0 Volts. During 
the time the solenoid is switched off, the voltage 
on this terminal is 12 Volts. Some 
motormanagement systems control the amount 
gases delivered to the intake manifold switching 
the solenoid on and of with a certain duty cycle. 
In this case the duty-cycle depends on engine 
RPM and engine load.

Electrical diagnosis

STATIC

General 

  

To perform this measurements the relay switching the power to the solenoid
should be closed. Short circuit the switch in the relay if necessary. 

Measurements

Measure the voltage on the control unit. Use the pin which switches the 
solenoid.

12 V

result:

solenoid and wiring are electrically OK

0 V 

check the relay switching the power to the solenoid
check the wiring between the relay and the solenoid
check the solenoid resistance
check the wiring between the solenoid and the control unit
check the control unit
