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

2006 Mazda codes P0455 P2198 P2189 P2187 P2196. Dont know where to start looking for problem. Bought a new gas cap. Trouble starting after I fill the tank but after I get it started the first time no...


P0455 Evaporative Emission Control System Leak Detected (large leak) P2198 O2 Sensor Signal Stuck Rich (Bank 2 Sensor 1) P2189 System Too Lean at Idle (Bank 2) P2187 System Too Lean at Idle (Bank 1) P2196 O2 Sensor Signal Stuck Rich (Bank 1 Sensor 1) basically you need to replace either the air /fuel ratio sensor,, or,,the heater relay associated with that sensor,, these are very hard to diagnose without the hand held or scope that narrows it down ,, you can check a multitude of voltages on a number of electrical connections, as far as the P0455 ,, if you installed a new gas cap either have the code removed , or wait a couple of days and it should remove itself, as long as the cap is factory approved, Look for vacuum leaks in the evap system , cut hoses,, bad connections,

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

What does code p2189 and p2187 mean on kia sadona 2006 inspection rejected


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.
