P2008/58 INTAKE MANIFOLD RUNNER CONTROL
CIRCUIT / OPEN (BANK 1)
CIRCUIT DESCRIPTION
The swirl control valve is mounted on the intake manifold. The Vacuum Switching Valve (VSV) for swirl control valve changes the vacuum to actuate the actuator.
The ECM determines the opening angle of the swirl control valve, and uses the VSV for swirl control valve
to change the vacuum applied to the actuator’s diaphragm to open and close the swirl control valve.
DTC No.
DTC Detection Condition
P2008/58
Trouble Area
When actual intake air volume detected by MAF meter continues to be smaller than volume estimated from boost pressure
and intake air temperature sensor, ECM determines that swirl
control valve is stuck closed.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester II. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, if the engine was warmed up or not, and other data from the time the malfunction occurred.
When using intelligent tester II:

CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P2008/58)
Connect the intelligent tester II to the DLC3.
Turn the ignition switch ON and turn the intelligent tester II ON.
Enter the following menus: Powertrain / Engine / DTC.
Read the DTCs.
