P2187-Fuel Trim System Lean at Idle--
If you have a cold air intake on your 2009 HHR turbo, it been know to happen. Your HHR is still under warranty so take it to the dealer, the code indicates that the engine is running lean when at idle but is running fine what engine is under load. It could be a simple update to the soft wear to the ECM to the HHR or a faulty MAF, regardless use the warranty you have and have them get your HHR running 100% again.
Thank you for using Fixya.

SOURCE: Check engine light came on and is giving codes

check for a broken vacuum hose or vacuum fitting(s). you can use a can of spray carb cleaner. while running the engine use the spray to test hoses and fittings. give a little squirt to suspected areas. The idle speed will change when you find a vacuum leak. pay particular attention to the hose to the MAP sensor. There may be a problem with the elelctrical connection to the map sensor, or the sensor itself may be bad.

SOURCE: Check engine light is on

The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" Air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry

There could be a vacuum leak downstream of the MAF sensor

In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling

Inspect all vacuum and PCV hoses, replace if necessary

Check for a dirty fuel filter and proper fuel pressure

P2187 code on 2006 sonata v6


(adsbygoogle = window.adsbygoogle '' []).push({});

P2187 System Too Lean at Idle (Bank 1) DTC
OBD-II Trouble Code Technical Description
Article byDon BowmanASE Certified Automotive TechSystem Too Lean at Idle (Bank 1)
What does that mean?
This diagnostic trouble code (DTC) is a generic powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may be slightly different depending on the model.
(adsbygoogle = window.adsbygoogle '' []).push({});
This is an ambiguous code in of itself. It can be a tough code to crack without a diagnostic strategy. During the last two starts, the engine management computer has recognized a problem with the fuel mixture at an idle.
It appears that the fuel mixture is too lean (too much air and not enough fuel) at an idle. If you have a 4 cylinder engine the "Bank 1" is meaningless, however, if you have a 6 or 8 cylinder engine, Bank 1 will be on the side with the number one cylinder. Code P2189 is the same code but for Bank #2.
There is a laundry list of components that could cause this scenario. For the most part the diagnostic procedure is not difficult -- just time consuming, unless it is one of the first items checked. The strategy dictates that the driveability problems are observed and noted, then start with the most commonly found problems and progress from there.
Symptoms
With the wide range of possibilities, the problems listed may and may not be present. But, here is where it is important to pay particular attention to the symptoms observed and make a note as to what and when symptoms appear for diagnostic strategy.
Vehicle has a miss at an idle
Hard to start, especially when hot
Very irregular idle
Additional codes to pinpoint cause of original P2187 code
Whistling noises
Lower turbo boost numbers
Fuel smell
Potential Causes of P2187 DTC
Faulty O2 sensor (front)
Faulty gas cap seal
Leaky or loose oil filler cap
Air leaking into the intake manifold downstream from the Mass Airflow sensor due to the manifold itself, vacuum hoses off or cracked, leak MAP sensor, Leak at turbo bypass or it's stuck open, power brake booster hose, or a leak in the EVAP system hoses.
Faulty MAP sensor
EVAP canister purge valve
Fuel injector leak
Fuel pressure regulator faulty
Leaks in the exhaust system
Faulty variable camshaft timing
Faulty ECM (engine management computer)
Faulty O2 preheater (front)
Clogged fuel filter
Fuel pump wearing out and producing low pressure.
Faulty mass air flow sensor
Diagnostic / Repair Steps
Your strategy for locating this problem begins with a test drive and observation of any symptoms. The next step is to use a code scanner (available at any auto parts store) and pulling any additional codes.
The computer has set a code P2187 stating that the fuel mixture is lean at an idle. This is the main code, however, any component malfunctioning within this loop that has the potential to cause a lean mixture will also be set in code.
If the test drive doesn't produce any symptoms it is possible that it is not a real code. In other words, the fuel mixture is not lean and that the computer or oxygen sensor is responsible for setting the code.
Every vehicle has a minimum of two oxygen sensors -- one in front of the catalytic converter and one after the converter. These sensors signal the amount of free oxygen left in the exhaust after ignition, which determines the fuel ratio. The front sensor is primarily responsible for the mixture, the second sensor behind the exhaust is used for comparison to the front sensor to determine if the converter is working properly.
If a rough idle is present or one of the other symptoms, begin the process with the most likely cause first. Either unmetered air is entering the intake manifold or there is a lack of fuel pressure:
Check the fuel cap for cracks and sealing and function
Lift the hood and make sure the oil filler cap is tight
If additional codes were present begin with inspecting them first
Look for air leaks starting at the mass airflow sensor. Check the hose or connection between the sensor and the intake manifold all the way to the manifold for cracks or loose connections. Check all vacuum hoses carefully attached to the intake manifold, to include the one to the vacuum brake booster. Check the hose to the MAP sensor and all hoses to the turbo if so equipped.
With the engine running, using a can of carburetor cleaner and spray a small mist around the base of the intake manifold and where the two halves meet if it is a two piece. Spray around the base of the EGR for leaks into the manifold. The rpm will increase if a leak is located.
Check the PCV valve and hose for leaks.
Inspect the fuel injectors for external fuel leaks
Inspect the fuel pressure regulator by pulling off the vacuum hose and shaking it to see if fuel is present. If so replace it.
Shut the engine down and install a fuel pressure tester on the schrader valve on the fuel supply rail to the injectors. Start the engine and note the fuel pressure at an idle and once again at 2500 rpm. Compare these figures with the desired fuel pressure found online for your vehicle. If out of range in volume or pressure replace the pump or filter.
The remainder of components need to be inspected by a service facility that has a Tech 2 scanner and programmer.

I have checked the data sheet and I have no reference for the code you have given. All I can tell you is that it could be a poor or no connection to the air heater element or a wiring harness fault near the air intake air pipe.
