Hi, I have a VW EOS 2007, check eng light on, 008583 - Bank 1; System too Lean at Idle P2187 - 004 - - MIL ON, then, 004369 - Oxygen (Lambda) Sensor Regulation: Bank 1


The O2 sensor is most likely the issue. Also, try cleaning the Throttle Body Injector with cauberator cleaner or tbi injector. Build up within the TBI may be causing a gas deficiency which causes it to run lean. If that doesn't help, try running a higher octane fuel, about 93 octane minimum. This will causes ANY debree in the injectors to be cleared.

Problem code p2187


code p2187 refers to system too lean bank 1==causes -- fuel pressure--injectors--intake leak---ECM It also refers to adaptive heated oxygen sensor (HO2S) control bank 1 no signal===causes --wiring ---HO2s---ECM Have a pressure test done on the fuel manifold to check fuel pressure ,regulator and filters.. Check for vacuum leaks in the manifold including all hoses.. Replace the oxygen sensor.

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

P2197 p2187 p2177 p2195 p2179 p2189


P2197 - Oxygen Sensor Signal Biased/Stuck Lean Bank 2 Sensor 1
P2187 - System Too Lean At Idle Bank 1
P2177 - System Too Lean Off Idle Bank 1
P2195 - Oxygen Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1
P2179 - System Too Lean Off Idle Bank 2

I am not sure what your Mazda is, but from the sounds of it, both of your Oxygen Sensors are shot. Replace them both, or check for vacuum leaks. It may be a good time to inspect and replace the PCV Valve and PCV Valve hose, too.

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

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.
