Hello,

These two hoses go through your vehicle's firewall and go to it's heater core. One takes the coolant to the heater core and one takes the coolant from the heater core back to the intake manifold. I have included what information I can find on the heater hose below in a link (it is for heater hose replacement but I provided it for information only).

Please go through the guide and do not be afraid if you have any other vehicle related questions to ask.

Thanks,
Alex

Not heater hoses. This hose goes into the back of the intake manifold and then down the back side of the engine. Appears to be a vacuum.

Hello again,

Okay, my bad. Without seeing it sometimes it can be hard to get it on the first try. This is going to be your EVAP line coming your vehicle's charcoal canister. This is the final step in your vehicle's evaporative emission system that catches fumes from the fuel tank and stores them in a charcoal canister until your vehicle's Power-train Control Module (PCM) decides to purge them, then is opens a valve and they get introduced through the hose in question into the intake manifold where it is burned in the engine. I have included a factory description of how your vehicle's EVAP system works in the diagrams down below.

Thanks,
Alex

Thanks. I've got it from here. All the diagrams I found, show it on the manifold but failed to identify it or show the hose that connects to it. Now to identify a part number and I'll have the issue solved. Thanks again.

The check engine light is on. The code reads p1537. (IMRC) intake manifold runner control. Engine is 2.3L. It says possible causes are vacuum leak, but I did not find one. Also flap could be stuck open but they seem to be free. It also mentions something about a swirl control valve. What is it and where is it located? Could carbon be the problem? What all should I check or what should I replace? I will appreciate any help. It has been very confusing and frustrating.

Hi
1537 means ICRM is not closing in required time most likely faulty actuator. see diagrams

I have a 2002 Ford Ranger and recently had the check Engine light come on. WHen I checked the code it came back as 1537 which I am told means hat the "Intake Manifold Runner Control is Stuck Open on Bank 1". Can you tell me what this means and what has to be doe to correct it?

Thank you

Not too familiar expressly with Rangers, but the imrc I think is a remote mounted actuator motor with cables attached to the butterfly valves on each bank, there mat be two cables or only one depending on application, the actuator sends signals to the pcm indicating butterfly valve and cable positions, be careful, the levers and return springs are strong, keep your hands and fingers clear of levers and so on. Check cables, levers and valves, make sure none are binding, obviously in your case, something is being held incorrectly, the runners are sticking, the actuator(s) has(have) failed, cable problem, or faulty wiring issue

Found it could be the ECM - engine control module. Where is this located and how do you check it?

Why are you suspecting the ECM? That is the least likely cause of that issue.

When I looked up the code it said to check it. I checked more & will check vacuum lines on intake manifold runner control valve. I found out where it is now. I'd never heard of it before.
