    I have a 2003 saab 9-3 2.0t with a check engine light on and the exact same codes. The idle fluxuates between 1100-1300 at stops unless I have the AC on in which case the idle drops down to a steady 1000-1100rpm. I have cleared the codes with an OBD scan tool and the idle goes down immediatley, but the car feels like it is going to die at stops for a day or two until the light comes back on at which time the idle is back above 1100.

    i have a 2006 hyundai sonata with 75,000miles and the check engine light came on the other day, i read the code and it came up as "P2187-System too lean at idle speed ( bank 1)

    Have the same problem with my 2003 Saab 9-3 2.0t. Same two engine codes -- anyone have a solution or at least a place to start looking??

    Try checking the vaccum hose down near where the oil dipstick is, a simple crack in the hose could be causing the check engine light to turn on.

    Try checking the vaccum hose down near where the oil dipstick is. A simple crack in the hose can be causing the check engine light to trigger.

The following are generic OBD II codes so your Sabb may not conform:
P0507=Idle Control System RPM High

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.

Error codes P0507 and P0102 after replacing MAF sensor


P0102: you need to make sure the sensor is clean; sometimes it get dirty as you are working on an old car. Check the voltage manually. Make sure there is no air leak near it

P0507: high idle... this sounds like a vacuum leak. get starter fluid and start the car. Spray around and check for change in car idle

P2189: Sys Too Lean at Idle Bank2
P2187: Sys Too Lean at Idle Bank1

The other codes P2189PD & P2187PD are pending codes.. Meaning the car will have to recheck the errors before it calls it an error and sets the engine light on. They are the same codes as the others just the PD at the end means pending.

I have code p0507 & p2187 on my 2004 Saab 93 the idle is rough



Combustion engines operate by burning an air/fuel mixture of about 14.7 to 1-14.7 parts air to 1 part fuel. When the air ratio goes below 14.7 parts, this is called a "rich" mixture. If the air rises above 14.7 parts, it is called a "lean" mixture.

Rich Mixture = Too much fuel, not enough air
Lean Mixture = Too much air, not enough fuel

To keep the engine running properly, the Engine Control Module measures the oxygen content in the exhaust with oxygen sensors and makes adjustments to the mixture by injecting more or less fuel.

P0507 Idle Control System RPM Higher Than Expected

P2187 System too lean at idle

Things to check:
1. MAF
2. Fuel pressure, fuel pump flow rate

Do you have cold air intake?

Run a fuel system cleaner first and reset software. Long Term Fuel Trim Additive. Max Value, Air/Fuel too Lean.

Code P2187


P2187 System Too Lean at Idle (Bank 1)

Check the MAF. this could be the reason for the O2 reading lean. if the MAF is ok and, the sensor is not damaged, replace the Os sensors.
