Manufacturer control fuel air metering p1132 - 2001 Subaru Forester

I will try to paste an article for you. Several sources indicate this is a Bank 2 O2 sensor problem and that it is failing to switch and adjust for the fuel mix. But as you can see, many defects can lead up to this O2 sensor Code 1150.

I would try to use a spray bottle of water and go around the Intake manifold and spray the water while the engine is running. An intake leak will draw water into the engine and change RPM.

If no success then try changing the O2 bank 2 sensor. You may need to wipe the computer and clear the Code. H40 DTCs P1131, P1132, P1151 AND P1152: UPSTREAM HO2S NOT SWITCHING. DTC P1130: FUEL SYSTEM NOT SWITCHING AT FUEL TRIM (RICH OR LEAN)
Diagnostic Trouble Codes (DTCs) P1131 bank 1 (Cylinder 1) and P1151 bank 2 indicate the fuel/air ratio is correcting rich for an overly lean condition. The HO2S voltage is less than 0.45 volt. DTCs P1132 bank 1 (Cylinder 1) and P1152 bank 2 indicate the fuel/air ratio is correcting lean for an overly rich condition. The HO2S voltage is greater than 0.45 volt.
DTC P1130 and P1150 indicate the fuel control system has reached maximum compensation for a lean or rich condition and the HO2S is not switching.
DTC/HO2S Reference List
•HO2S-11 = DTCs P1131, P1132 and P1130
•HO2S-21 = DTCs P1151, P1152 and P1150
Possible causes:
Fuel system
•Excessive fuel pressure.
•Leaking fuel injector(s).
•Leaking fuel pressure regulator.
•Low fuel pressure or running out of fuel.
•Contaminated fuel injector(s)
•Vapor recovery system
Induction system
•Air leaks after the MAF.
•Vacuum leaks (vacuum lines and gaskets).
•Restricted air inlet.
•PCV system.
•Improperly seated engine oil dipstick.
EGR System
•Leaking gasket.
•Stuck open EGR valve.
•Leaking diaphragm.
Base engine
•Oil overfill.
•Cam timing.
•Cylinder compression.
•Exhaust leaks before or near the HO2Ss.
•Check intake air system for leaks, obstructions and damage.
•Check air cleaner element, air cleaner housing for blockage.
•Verify integrity of the PCV system.
•Check for vacuum leaks. )

Hello,
P1132 = Lack of HO2S11 switch. sensor indicates rich.
The HO2S11 is the upstream oxygen sensor. ( upstream meaning it's before the catalytic converter.)
This sensor is telling the ECM, ( electronic control module ), to increase the fuel, which is why it's indicating RICH. ( the fuel/air mix ratio should be 1 part fuel, 14.7 parts air )
The most common reason for your issues are the following.
1. Dirty air filter.
2. Faulty/dirty idle air control valve.
3. Faulty/dirty MAF, ( mass air flow ), sensor.
Until you're able to get this fixed, you are going to get poor fuel efficiency

I hope this helps you.
Thanks, Donnie

p0161 is o2 sensor heater circuit malfunction(bank 2 sensor 2) p1132 is manufacturer control fuel air meter. Hope it helps a little. I have a 99 V70xc AWD I know they can be.

my 2000 ford escort se is bucking & jerking like a horse,the muffler shop says it's the manufacture fuel air control metering,where is it located & how much will it cost?.where would i go 2 have it fixed.or can my husband fix it?

Code p1131 manufacturer control fuel air metering, on a 2003 Ford Taurus. Where is part? Is there an easy way to see if it can be fixed without buying the expensive part?

The P1132 I believe is a bad mass flow sensor or a vaccum leak

The P1132 I believe is a bad mass flow sensor or a vaccum leak.

uplug air metering sensor car should run almost normal but will set check eng, light

Try looking at the idle/air control valve - Look around where the gas cables attach to the engine. remove the wires and then unbolt the unit from the engine. The control valve has a spring valve that you can clean with intake cleaner. re-install the valve and drive to warm up the vehicle. After 20 minutes the vehicle should Idle. If not clear all codes and relist them here - hope tthis helps
