SOURCE: what does code p2189 and p2187 mean on kia sadona

code p2189 and p2187 = 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.

SOURCE: I have code p0507 &


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.

Fault symptom


Malfunction Indicator
Lamp

The engine may stop after starting, run unevenly and misfire or run
at high rpm.

12%.

Fault criteria:

The additive adaptation factor is greater than 5.25%.

Diagnostic help

Diagnosis
regards:


Checking air/fuel ratio. With this DTC, the engine will be getting too much air or too little fuel.IMPORTANTA crankcase ventilation leak may be one reason as to why a DTC is set. Check crankcase ventilation function before starting regular troubleshooting.

Code p2189 code p2187 code p2189pd code 2187pd


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.

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.
