The P2187 code indicates that there’s an issue with the air-fuel mixture ratio. Combustion engines typically require a mixture ratio of 14.7+/-2 parts air to one part fuel; if the system notices that the mixture is especially off one way or another, then it will send an error. This code indicates that the system is too “lean,” which means that there’s more air than expected and not enough fuel.
More About the P2187 Code
This code doesn’t trigger the first time there’s an issue with the air/fuel mixture. Instead, the powertrain control module (PCM) will try to inject more fuel into the mixture when it first notices an issue with the mixture. The code will only trigger if the adjustments become too large or if the engine is unable to create the proper ratio even with adjustments.

What Are the Symptoms of a P2187 Code?

What Are Some Causes of a P2187 Code?
The core cause of the P2187 code is that the air/fuel mixture is off in some way. However, the reason for this issue can vary significantly. It may be due to an issue with the mass airflow, oxygen, or air-fuel ratio sensor, leaks within the vacuum, a weak fuel pump, a leak in the exhaust, or a clogged fuel filter. The array of reasons that a P2187 code may appear is one of the reasons that it can be difficult to recognize and fix.
