I have a 2002 Ranger with a check engine warning light. The code is P1537, a little research proved the code to be "Intake Manifold Runner Control Stuck Open." Does anyone have knowledge or experience with this fault and how to correct it? Replies to this message: roofranger (Oct 09, 2008 2:11 pm) yesibrokeit (Nov 19, 2008 6:15 pm)

Replying to: 2002ranger2 (Sep 15, 2008 5:58 am) If you have the small 4 cyl engine, I had the same problem. Check the vacuum hose that runs to the control valve on the intake manifold at the fire wall on the drivers side. Mine was cracked and leaking. The port at the intake was also clogged and was cleaned out with carb cleaner. If you have a hand pump vacuum tester you can supply vacuum to the control to make sure the diaphragm is intact and the port is not clogged.    This control restricts intake flow at engine rpm less than 3000 to enhance low end torque. When it is stuck open the butterfly is open all the time and your low end torque is less, but your gas milage is better (my experience). It is not hard to remove the intake and clean it all out around the butterfly to make sure it is not so dirty as to be sticking. Replies to this message: yesibrokeit (Nov 19, 2008 6:15 pm)

#13 of 32 No OBD reading at diagnostic plug by johnster1 Oct 30, 2008 (4:06 pm)
What is the trouble code for no trouble codes?   '02 Ford Ranger has check engine light on, but the OBD code reader which I bought indicates no power in the diagnostic connector under the steering wheel. I checked this with two known working code readers, and got same results.   Does anyone have any experience with a bad OBD module, and if so, how do you test it.   The truck runs fine. I did take a hit in the tailgate a while back, but cannot say the light came on at that time.   I am guessing a problem in the harness, or what the harness hooks to. Any ideas?
