EXHAUST CONTROL SOLENOID VALVE

Electrically operated valve controlled by the vehicle control unit, ECU, which under certain conditions, allow to pass the pressure and/or vacuum from the intake or exhaust system to other systems or components by acting on another component.

TYPES

• EXHAUST CONTROL SOLENOID VALVE:

It opens when the Engine Control Unit (ECU) detects the need for exhaust gas recirculation, allowing the mechanical Exhaust Gas Recirculation (EGR) to engage by creating a vacuum.

• AIR INTAKE SOLENOID VALVE o transductor de presión:

Under specific conditions, they allow the transmission of pressure/vacuum to affect the intake manifold’s geometry or influence the turbocharger’s operation.

LOCATION

They are interspersed within the vacuum lines of the systems they operate on.

COMMON FAULT SYMPTOMS

• Blockage or sticking
• Vacuum leaks
• Faulty electrical connections
• Solenoid failure
• Engine Control Module (ECM/PCM) error
• Vehicle error code
• Poor engine performance

FAULT EFFECTS

• Loss of power
• Increased fuel consumption
• Rough idling or unstable idle
• Unwished emissions
• Engine warning light on
