What causes code P2187?

What Does P2187 Mean? Combustion engines run most efficiently when they maintain an air-fuel mixture ratio of 14.7 parts air to 1 part fuel. When there are more than 14.7 parts air to 1 part fuel in the air-fuel mixture, a lean condition exists and code P2187 is triggered when this is noticed at idle on bank 1.

How do I fix error code P2189?

What repairs can fix the P2189 code?

Repair of a leaking air intake.
Replacement of a faulty gas cap seal.
Repair or replacement of leaking exhaust system components.
Repairing a mechanical issue in one or more of the bank 2 fuel injectors.
Replacement of a faulty manifold absolute pressure sensor.

What does po171 code mean?

The P0171 code means that, on the first bank of the engine, the fuel system is running weak or a vacuum leak exists near this side of the engine. A lean condition occurs when the engine either receives too little fuel or too much air.

What does the trouble code p2187 mean?

What the P2187 code means. The P2187 trouble code means there is an issue with the vehicle that is causing a lean fuel mixture.

What causes the p2187 DTC system to lean at idle?

Potential Causes of P2187 DTC. 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.

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.

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.
