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

SOURCE: engine codes P0101 and P0170

P0101 Mass or Volume Air Flow Circuit Range/Performance Problem
Air flow sensor problem, maybe causing the second code to go off.
The air flow sensor should be right near your air filter box.

SOURCE: CHECK ENGINE LIGHT ON CODE P0170

DTC P0170 applies to fuel trim malfunction on all 2.4L vehicles, 3.0L Federal vehicles and right bank (bank 1) on 3.0L California vehicles. 
DTC P0173 applies to fuel trim malfunction on left bank (bank 2) on 3.0L California vehicles.
DTC Set Criteria (2.4L)

Engine is in closed loop control. Intake air temperature is more than 14°F (-10°C). Barometric pressure is more than 11 psi (76 kPa). Volume Airflow (VAF) sensor output frequency is 88 Hz or more. Code will set if long-range fuel correction is less than -12.5 percent, or more than +12.5 percent, for 5 seconds and short-range fuel correction is less than -10 percent, or more than +10 percent, for 5 seconds. 

Engine is in closed loop control. Intake air temperature is more than 14°F (-10°C). Barometric pressure is more than 11 psi (76 kPa). VAF sensor output frequency is less than 88 Hz. Code will set if long-range fuel correction is less than -12.5 percent, or more than +12.5 percent, for 5 seconds. On 2.4L code will also set if short-range fuel correction is less than -15 percent, or more than +15 percent, for 5 seconds. On 3.0L Federal code will also set if short-range fuel correction is less than -13.5 percent, or more than +13.5 percent, for 5 seconds. 

Have the O2 Sensor changed on the Right Bank, ( passenger side of the Engine, or where the # 1 cylinder is.)
Good luck and hope this helps

Hi!!
What all this codes have in common is that every single one of them can be caused by a vacuum leak, so carefully check for cracked, loose or disconnected vacuum hoses, wiring to the coils, fuel pressure regulator, fuel injectors, specially on cylinder 2.

  • PO100 - Possible causes are wiring harness failure, air leak or defective hot film MAF sensor
  • PO130 - Vacuum leak
  • PO170 - PO173 - Possible causes are air ingress (leak), fuel injector failure, pressure regulator failure or mechanical wear of engine. Inspect and repair as necessary.
  • PO300 - possible causes are vacuum leak, wiring harness failure or ignition coil defective.
  • PO302 - If limit value for misfire "harmful to TWC" is exceeded, the MIL flashes immediately. If too many combustion misfires occur in one cylinder, the cylinder is switched off (cylinder selective fuel shut off). After the affected cylinders are shut off, the MIL changes from flashing to continuously lit until next time the engine is started. If combustion misfires are recognized, the fault code P0460 or P0462 is set if fuel tank level is too low (fuel reserve indicator light is on). Combustion misfires due to a shortage of fuel are recognized by means of this additional information.

NOTE:After cylinder cut-out system is turned off, the system monitors (through misfire detection) if all intake and exhaust valves are open again.
NOTE:Misfiring may be caused by many faults in the fuel injection system. Usually a misfiring fault is stored with faults pertaining to other components. An engine mechanical fault could also cause a misfire condition.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

    What causes a P0170 code


    P0170 Fuel Trim Malfunction (Bank 1) OBD-II Trouble Code Technical Description Article by Dale Toalston ASE Certified Technician Fuel Trim Malfunction (Bank 1) What does that mean? This code is one that surfaces with certain makes of automobiles more than others. In writing this article I've added Mercedes-Benz-specific info since it seems that M-B (and VW) are most prone to having this P0170 surface along with misfire codes or other fuel trim codes. P0170 means there was a malfunction in the computer's control of the air:fuel ratio. It also indicates that the fuel trims reached their limit of adding fuel while trying to compensate for a actual or perceived rich condition. When the fuel trims reach their rich correction limit, the PCM (Powertrain Control Module) sets a P0170, indicating a problem or malfunction in the fuel trims. It may also have a P0173 referring to the same malfunction but on bank two. Symptoms Symptoms of a P0170 DTC may include: MIL (Malfunction Indicator Lamp) Illumination Start and stall Poor fuel economy Black smoke at tailpipe Hesitation/misfire at idle or under load Causes Potential causes include a vacuum leak, unmetered air leaks Fuel saturated engine oil Leak in turbo air charge hoses (if equipped) Possibly bad O2 sensor (If Mercedes, may require adaptation with M-Benz compatible scan tool.) Oil contamination in MAF connector or O2 sensor connectors. Also check ignition coils, cam and crank sensors, and oil sensor for leakage contributing to oil intrusion in wiring harness. Defective MAF (Mass Air Flow) sensor (especially on Mercedez-Benz and other European autos. There are a lot of problems with aftermarket MAF sensors.) Defective fuel pressure regulator Leaking camshaft adjuster solenoids (Mercedes-Benz). NOTE: for some Mercedes-Benz models there is a service recall for a crankcase vent hose located under the intake manifold. It should be checked for leaks/cracking and also operation of check valve in the hose. The check valve should flow only one way. Possible Solutions It should be stated right off the bat that the most common problem associated with this code is the MAF sensor or air mass meter. This is especially the case with Mercedes-Benz and Volkswagen and other European cars. At time of writing, you don't normally see this code with American-made cars, and minimally with Asian, and, to be honest, I have no idea why. It appears to me that the PCM (powertrain control module) logic used by some European car manufacturers to set a P0170 (or P0173) fault code simply isn't used by American vehicle manufacturers. It is more common to see P0171, 0174, 0172, 0175 codes set with regard to fuel trim malfunctions on American cars. There is very little information on the setting conditions for a P0170, or P0173, but what information that is available almost seems to be a redundancy of the P0171,4,2 & 5 setting conditions. I'm sure there's a reason for it, but I can't get anyone to tell me what that is. The similarities between them may be why we don't see this code surface on domestic vehicles very often. It's simply unnecessary. So, simply put, if you have a P0170, your PCM noticed that the fuel trims reached their rich correction limit. Basically it's adding fuel to try to compensate for a lean condition, real or perceived. If you have this code and access to a scan tool, observe the MAF sensor reading in grams/sec. The reading will be different for different automobiles, so get a good spec. I'm going to stick with what would be normal for a Mercedes (1.8L), since they have the bulk of the trouble. Expect to see at idle 3.5-5 g/s (ideally). At 2500 RPMs with no load it should be between 9 and 12 g/s. On road test, at WOT (wide open throttle) it should be 90 g/s or well above. If it's not in specs, replace it. Be careful of Ebay MAFs. Often they don't work according to OE specifications. If the MAF checks out and there is no oil intrusion at the connector, check fuel pressure and ensure that there are no leaks at the regulator internally or externally. Check all vacuum hoses and confirm none are cracked, disconnected or missing. Make sure there are no vacuum leaks at the intake manifold gaskets or tears in the air supply hose. If the engine is turbo charged, be sure the hoses are in good condition and have no leaks. Leaking turbo pressure hoses could cause a rich condition. Inspect the condition of crankcase vent hose under intake manifold and operation of check valve in the hose. (In the "What are the causes?" section) If there doesn't appear to be any problems with the fuel pressure, MAF or vacuum hoses, then inspect the O2 sensor connectors for oil intrusion. A bad O2 sensor could cause a P0170, or P0173. Repair cause of oil leak and replace oil-fouled O2 sensor.
