P0443 but I've replaced everything - 2000 S70 AWD

Post by AustinAbney » Sun Apr 28, 2019 10:17 am

Keep getting the P0443 code which is leaving me unable to renew my tag. So far, I’ve replaced the following:

1. Purge valve (twice)
2. Fuel shutoff valve (twice)
3. Hose from the purge valve that “y’s” out to the intake manifold and engine intake hose
4. J-pipe

Any other ideas?

My bad. I was multitasking when I made this post. I'll adjust the content and title.

I have a code P0443, not P0043. Doh!

Now, any ideas anyone?

You got a open, short or a power supply failure in the loom to the Purge Valve.

1. Check/clean the connector to the Purge Valve.
2. Make sure the Purge Valve is getting power.
3. Ohm out the loom for shorts and opens.

I'll get looking. Any chance the B+ cable from the battery could have anything to do with this?
