What to do if you find a p2187 Hyundai problem?
If you find a P2187 P2189 Hyundai trouble code, don’t start throwing parts at the problem. The two codes P2187- bank 1 system lean, and P2189- bank 1 system lean may lead you down the wrong path of thinking you’ve got a fuel delivery problem. Most DIYers start by changing the fuel filter, checking the fuel pressure, or cleaning the fuel injectors.
What are the p2187-bank 1 system Lean codes?
The two codes P2187- bank 1 system lean, and P2189- bank 1 system lean may lead you down the wrong path of thinking you’ve got a fuel delivery problem. Most DIYers start by changing the fuel filter, checking the fuel pressure, or cleaning the fuel injectors.
What causes a p2187 code leak in the exhaust system?
Additional codes to pinpoint cause of original P2187 code 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. Leaks in the exhaust system
How does the p2191 Hyundai Powertrain Control Module work?
P2191 HYUNDAI Description In order to provide the best possible combination of driveability, fuel economy and emission control, the Powertrain Control Module (PCM) uses a closed loop air/fuel metering system. The PCM monitors the HO2S signal voltage and adjusts fuel delivery based it in closed loop fuel control.

How does the p2191 Peugeot fuel system work?
The PCM monitors the HO2S signal voltage and adjusts fuel delivery based it 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.
Why is my p2189 code leaking into the intake manifold?
Additional codes to pinpoint cause of original P2189 code 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. Leaks in the exhaust system
How does the p2189 system work at idle?
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.

What does the p2187 OBD-II fault code mean?
The P2187 OBD-II fault code means the vehicle’s on-board computer has detected a lean fuel mixture at an idle in either Bank 1 or Bank 2 (the side of the engine with the corresponding number on the cylinder, if applicable). A lean fuel mixture means there is an excess of air and a shortage of fuel.

Is the code p2189 the same as Bank 2?
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.
