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
