On the '03 2.3L there is something called a "Swirl Control Solenoid Valve" assembly which is "a manifold–mounted vacuum actuator and a PCM–controlled electric solenoid, with the linkage from the actuator attaching to the manifold butterfly plate lever." I would suspect the P2004 problem lies somwhere in this.

Thanks a lot for the info. Unfortuately A drunk driver hit me in the rear and rolled the truck 6 times. It's a total lost as you could imagine. So I don't have to worry about it now.

I'd like to reopen this thread. We have a 2002 Ranger with the 2.3 and have code P1537 for the IMRC being stuck open.

I would like to test the diaphram assembly and would like to know the amount of vacumn required to start opening (and coompletely open) the diaphram. I'm afraid my breath isn't as good as it used to be, although I can hear something moving when I try it.

I'll run a test on the vacumn selenoid switch in the morning.

Dtc P2004

After reading through three pages and finding no answers on this problem, I just went out and looked for it on my Mazda B2300(Ranger). Found it right away. It's a small vacuum solenoid just under the intake manifold but above the starter. The bottom vacuum line going into it was broken, most likely because it's a bit short and was bent funny, plus engine bay heat and such. So for anybody else with this code, check that solenoid first, it's a 30-second freebie fix.

"Goodbye" We just had a B2300 come in with the code everyone has discussed above. It was exactly the hose you said it was. Thanks for posting the information.

how to clear the code (P1537) after fix?

Hi. My Dad has a 2002 B2300 with the 4 cylinder engine and it had this same code (P1537). We followed the advice given before; look for a bad vacuum line going into the IMRC solenoid and sure enough the lower vacuum line was cracked. We replaced it in about 5 minutes but now the "Check Engine" light is still on. I was hoping by replacing this line, the "Check Engine" light would go off but it hasn't. Does this particular fault require a "reset" command via the OBD II port or will it reset itself after a certain number of "off/on" cycles of the ignition switch?
I'm hoping it just needs to be reset via the OBD II port because if it was supposed to have gone off immediately after the fix, it means we have another problem.

Thanks for reading this, Scott

The check engine light should go out after three cycles without an error code. Just keep truckin'

Check the codes again if it doesn't go off.

Broken Vacuum Hose

Thanks for the great advice posted here, All.
Replacing the vacuum hose fixed my P2004 error on a 2003, 4 cyl, Auto.
I was surprised that the light went out immediately...no need for 3 start/stop cycles.

Extra clarification: The valve is located under the intake manifold near the firewall.

im actually a mechanic and working on a 2003 ranger 4 cyl. 2.3 L and yes i would inspect the vacuum hoses at the intake. For the one im working on the outer shell that holds the hoses to the solenoid has come apart which is why the code of P2004 was set. Very easy and inexpensive fix.
