SOURCE: 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.

SOURCE: Hyundai Sonata 2006 - Check Engine light came on.

"Fuel system too lean at idle". It's an air/fuel ratio that is not correct, possibly a vacuum leak somewhere. Or a leaky exhaust pipe. Could be related to intake manifold gasket. Somewhere, air is getting into the engine.

I suggest taking it back to the dealer under warranty. I think Hyundai is 10yr./100k for the original owner. 5yr./50k if not. Ask first if covered, and ask why not id not covered.

SOURCE: Got emission codes of P2187

Hi, The code p2189 and p2187 signifies that air/fuel mixture too lean on both cylinder banks which in turn generates excessive emissions = failed inspection.

What can cause a lean mixture:
- Incorrect main charge signal
- Intake air system leaking
- Fuel pressure too low
- Volume supply of fuel pump too low
- Mechanical fault in injectors
- PCV valve leaks
- Leaks in exhaust system
- EVAP canister purge valve mechanically faulty (hangs open)

All these must be checked to correct the problem

SOURCE: Engine code P2187 pops up. Also had miss in cyl 1

P2187 = "system too lean at idle, bank 1"

The problem is in the bank of cylinders that includes cylinder 1. Running too lean at idle can often be caused by an air leak between the mass air flow sensor and the throttle body, a leaky intake manifold gasket, or some other vacuum leak. "False air" is downstream of the MAF sensor so it is not measured. The computer only attempts to add the correct amount of fuel to air that it knows about. It will attempt to compensate for lean mixtures but at a certain point, it will turn on the check engine light.

The miss that you had on cylinder one was caused by two things; the false air leaning out the mixture and a worn plug. You replaced the plug and now that new spark plug is able to fire the lean mixture. But the false air remains to be corrected. Eventually, you'll have misfiring again.

Do I require any special tools to replace the driver's side rear reflector on the bumper of a 2008 Hyundai Vera Cruz. It appears to snap in, but I don't want to break it. Thanks.


There's nothing in the manuals about special tools. I have the same problem. I think you'll have to remove the lower bumper in order to get good access to it. It appears that there is a black housing screwed into the bumper from the rear side and the lens would snap into that.

2007 Hyundai Entourage codes P2187, PP0174,P2189,P2195,P2270,P2272


I've come across these codes before. In almost every case there was an air leak in the intake air hose (hose between the engine air filter & the throttle body). Inspect this hose & tubes attached to it. This is especially true when the lean code includes the comment 'at idle'
P2187 - System too lean at idle Bank 1
P0174 - System too lean Bank 2
P2189 - System too lean at idle Bank 2
P2195 = HO2S Signal Biased/Stuck Lean (Bank 1 Sensor 1)
P2270 = HO2S Signal Stuck Lean (Bank 1 Sensor 2)
P2272 = HO2S Signal Stuck Lean (Bank 2 Sensor 2)

P2187 & P2189 = In order to provide the best possible combination of drivability, fuel economy and emission control, the PCM uses a closed loop air/fuel metering system. The PCM monitors the HO2S signal voltage and adjusts fuel delivery based in closed loop fuel control. Changes in fuel delivery will be indicated by the long-term and the short-term fuel trim values. The ideal fuel trim value is around 0%. The PCM will add fuel when the HO2S signal is indicating a lean condition. Additional fuel is indicated by fuel trim values that are above 0%. The PCM will reduce fuel when the HO2S signal is indicating a rich condition. Reduction in fuel is indicated by fuel trim values that are below 0%. The DTC relevant to fuel trim will be set when the amount reaches excessive levels because of a lean or rich condition

Check all the bolts holding the plenum, and anything else concerned with air intake. Too much air means weak mixture.
