waht does code p2187 mean?

Question

I have a Hyundai Entourage with a code of P2187. If we change the engine filter, will the check engine light go off?

Answer 1

HI there,

Typically this lean code isn't a result of a dirty filter, but more of a condition brought on by the bank 1 O2 sensor, sensor 1. If you replace the sensor it will take some time for the light to go out on it's own. This is because the computer will have to run with the new sensor in it for a while to get the correct fuel trim. Then the light will go out.
