How to replace a swirl control solenoid valve?
The solenoid itself is very easy to replace, but difficult to track down. A few tips: Be very careful when removing it. It’s very easy to break either one of those solenoids, vacuum housing, or hoses. Remove the old one and write down the exact part number molded into the solenoid. Apply 12v to the solenoid when removed to makr sure it is stuck.
How can you tell if your swirl control solenoid is toast?
When you remove the solenoid, take a 9v battery and attach a wire to each terminal. Then touch these two wires to the two terminals on the solenoid. You should hear it click. If it doesn’t click, it’s toast. If it clicks, check to make sure air flows through it the right way.
How are control valves subject to common problems?
Control valves are subject to a number of common problems. This section is dedicated to an exploration of the more common control valve problems, and potential remedies. Control valves are mechanical devices with moving parts, and as such they are subject to friction, primarily between the valve stem and the stem packing.
How much pressure do you need to reverse a control valve?
Thus, a pressure reversal of 0.884 PSI (i.e. twice the equivalent value of packing friction) is required to make the valve reverse its direction of motion. This constitutes “deadband” in the control valve’s action, which degrades control behavior.
What is the solenoid valve on a swirl?
The solenoid valve controls swirl control valve’s shut/open condition. This solenoid valve is operated by the Engine Control Module (ECM). The swirl control valve control solenoid valve responds to signals from the ECM.
How does the swirl control valve work on a Nissan?
When the ECM sends an ON (ground) signal, the solenoid valve is bypassed to apply intake manifold vacuum to the swirl control valve actuator. This operation closes the swirl control valve. When the ECM sends an OFF signal, the vacuum signal is cut and the swirl control valve opens. Need more information on how to fix the P1130 NISSAN code?
How do you get rid of swirl valve?
All the solenoids do is open up to allow vaccum to the actuators. They are either open or shut. The knobs at the front are just dust covers. Once you have blocked the egr you can simply put a small ball bearing in the vaccum line that goes to the swirl valve actuator to disable it.
Where is the check valve on a swirl control valve?
If so, they have a check valve in them. Make sure you get the check valve in the right direction. They also have a mark on the outside which should line up with the retention brackets that you push the hoses into. Look at the other hoses running through the bracket and you’ll see the lines on the hoses.
