Engine codes code p1537 what is it,can i fix it, or do i have to go to an authorized ford repair shop?

P1537 CHEVROLET - A/C On Request Circuit Low Voltage

P1537 - Intake Manifold Runner Control Stuck Open.

You might want to look at the IMRC valve. It is probably sticking from carbon build up? Use top engine cleaner and clean the air plenum.

Once you have done this clear the codes and go for a ride. About 30 miles should do it. If you have anymore codes it will come back up.

DTC P1537 - Intake Manifold Runner Control Stuck Open Bank 1 and 2

It controls the length and speed of incoming air for a certain engine rpm to optimize swirl, efficiency, and minimize knocking. It's long and fast for low rpm and idle, short and large volume for higher engine loads. How's your truck running? I'm guessing it would be lean at idle if it's stuck open. I would look at your vacuum lines on the intake manifold. I think it would be vacuum operated.

Keep in mind that the IMRC Valves are located on the back of the intake and are listed as an item that the dealer needs to diagnose and repair.

Hope this helps.

Intake manifold runner control problem. IMHO, this is a completely unnecessary system. Is often problematic. check out this link for more info: http://www.carcomplaints.com/Ford/Windstar/1996/engine/engine_codes_P1537_and_P1538_IMRC_stuck_open.shtml

they are a ford specific codes they both are the same also :intake manifold runner control stuck open---the control is in the upper section of the manifold it may be stuck by sludge ,debris or carbon can try a carb spray cleaner if dont work may have to have repaired or replaced good luck

It could all be related.P1537/38 are the intake manifold runner controls are stuck open.They are controlled by vacuum solenoids.The P0171 is bank one of the engine is running lean,usually caused by a vacuum leak, P0420 is catalytic converter efficiency code. The computer monitors the switch rate of the front 02 sensors and compares it to the switch rate of the rear 02 sensors to tell if catalytic converter is doing its job. Now if the front 02 is not switching properly then this will cause this test to fail and set this code.
Look on bottom section of the intake manifold at the back of engine(where tranny bolts up) you should see the vacuum motors there on the intake,these are the control motors for the intake manifold runners.Make sure the vacuum lines are hooked up and lines are not leaking. Also you will see a lever from it to intake make sure they move and are not binding.

Here is a link with everything you need to know.
