W'ell before I investigate my coolant sensor, does anyone know if infrequent engine coolant changes can have an effect on the sensor reading? They also have a mark on the outside which should line up with the retention brackets that you push the hoses into. I'd expect a solenoid to have a return spring, but it may rely on vacuum, airflow, or something else for this. I can't remember the last time mine was changed. If you experince this problem. Glad I didn't buy the Cam Position Sensors. I've tried clearing the vacuum lines and that didn't clear the codes. If you experince this problem.
Confused me when I first saw the code on my reader as I didn't know swirl valves existed before that day. Got any good advice, or know about the emissions warranty law here in Colorado? I found 2 other instances where replacing that part permanently cleared the code, my case makes 3. I guess back to the drawing board. Took engine cover off, found the hole where you could see the actuator at the front top part of the engine to the immediate left of the swirl control valve solenoid, it was pretty rusted and was not moving freely. I'd expect a solenoid to have a return spring, but it may rely on vacuum, airflow, or something else for this. I'm pretty sure the solenoid didn't fail electrically.
Am I way off the mark on finding this thing? I am at my wits end here. My daughters 2001 Pathfinder is experiencing some strange problems. I am not getting any voltage reading by connecting it such a away. The total cost of the repair may be about max 60 us bucks depending on wether you get a new gasket and if you need a little fluid to top it off. Once the alternator is free - you can get at the battery cable post and the other wires. And did you install the new fuel pressure regulator and Do fuel pressure test.
Why the code reader and code list in Haynes can't just call it that I don't know. Take the following with a grain of salt, as I didn't even know what a swirl valve was until today. Very helpful, it will alarm and give pre-SvcEngineSoon errors. Also, except when idling and during low engine speed operation, this system opens the swirl control valve. There are 6 of them.
Other than color, it looks exactly like the swirl valve and has the same vac hose connections. Each serves a unique and different function within the engi … ne. Those who demonstrate they cannot follow the rules will be warned and posts removed. I would consider getting an Ultra Guage. The reason I didn't realize this is I didn't clear the code, which was intentional on my part since I wanted the code to still be there in case my repair didn't work so the shop could still see it if necessary. .
Most likely code will come back in a few days. I am not sure if there is a spring that is supposed to hold it in the open position. I've seen other posts here for others receiving the same code. Possible causes are as follows: Swirl control valve control solenoid valve is open or shorted. The wires are atleast color coated to help you. Took it into my Mechanic and he replaced the solenoid that operates this valve.
Unless there is a line that I am not aware of I don't think this is the problem. Changed all the hoses yesterday. This will allow people to filter out posts that have already been resolved so they can move on to other posts that still need assistance. Next some reading told me to blow out the vacuum lines with air--they get clogged up. I can replace that valve easy enough. Mine just started throwing the code.
This is a very common problem. I plan on splicing the wires by soldering and putting a shrink wrap on the connections for protection. So it winds up replacing the Swirl Control Valve Solenoid Valve actually fixed the problem after all! While idling and during low engine speed operation, the swirl control valve closes. Rattling sound in the engine when rev between 1. Once jacked up take off the wheel and remove the lower part of the wheel well gaurd. Typically that doesn't take too long to go away. I would consider getting an Ultra Guage.
I just hope that this helps give someone else a few things to try if they are having the same problem. I have cleaned all the switches and lines with brake clean however it still registers the same codes after clearing. I did replete my factory air filter box with a performance cone filter a few months ago, but this Swirly issue is only recent, so I am not convinced that is the issue. Has anyone else ran into this pesky code? However, please observe rule 1 when asking for a second opinion. I found the part online part numbers in my thread and fixed it first time. Body work questions regarding paint, dents, dings or accident related damages or other bodywork related issues should be posted in If you want an estimate you should take the car to a qualified body shop as they would know best what it will cost in your area and how to fix the damages. I am at my wits end here.
