What does p2187 mean on a car engine?

NOTE #1: Code P2187 indicates an issue with the air/fuel mixture when the engine is running at idle; issues with the air/fuel mixture when the engine is running above idling speed is generally indicated by other codes, some of which may be manufacturer specific.

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.

What is too lean at idle OBD code?

This is an ambiguous code in of itself. It can be a tough code to crack without a diagnostic strategy. During the last two starts, the engine management computer has recognized a problem with the fuel mixture at an idle. It appears that the fuel mixture is too lean (too much air and not enough fuel) at an idle.

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.

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
