P1130 code (Swirl Control Valve) - Infamous Nissan

haubstr · 02-18-2013, 07:14 PM

I have searched and read all of the posts on the P1130 code. I have a 1996 2.4L with 170K miles on it. It runs fine but I need to clear the code in order to pass the Smog check here in Cal.

I have done a full tune-up and changed vacuum lines where ever needed. I know there are a few more things to do but I'm starting from the easiest and least expensive first. I wouldn't mind changing the Swirl Control Valve and solenoid if I knew that was it and it fixes it. I'm not efficient with a multi or volt meter so checking the electric testing has to be simple.

If anybody has pictures on what they look like it would be appreciated. I have looked at the pictures in the Nissan Manual but the pictures don't look like anything I'm looking at.

Sorry this is long

Thanks in advance

Jamie

swirl control valve is (as you are standing front center looking at the engine, pass. side on left and driver on right) on the intake manifold at the back of the engine. it has a single vacuum tube going to it. this controls a shaft the goes from the back to the front of the intake manifold that has a butterfly valve (similar to a throttle body butterfly in the throat) in each of the intake ports. purpose is for better atomization of the air/fuel mixture during idle. here's some pics...

Thanks for the pic's. That was exactly what I was looking at on the intake.
In relation to the SCV, where is the SCV solenoid and what does it look like?
Have you had any experience or heard of these parts going out from anyone else?

Thanks again

Do you know if these can be changed without pulling the intake off?

I would follow the vacuum line from the SCV to the solenoid. IIRC its on the underside of the intake manifold on the brace to the engine... or close to. I would look more closely at the vacuum lines than the SCV or solenoid. go to www.nicoclub.com/fsm for a FSM of your year HB and look up the code it will tell you what to look for.

Nice pics, Dave! Super Dave to the rescue!

Before you replace that valve, your ECU would also throw that code if there was a vacuum leak or loss of electrical signal from the sensor (even temporarily).

Check the vacuum lines, looking for cracks or splits. Then look for the sensor connector and make sure the connection is not getting corroded.
