I have dodge grand caravan sport the check engine is on the code is P0172 say sistem too reach bank 1


code p0172 refers to system too rich bank 1===causes --intake blocked (air filter) EVAP canister purge valve---fuel pressure---EGR system--injectors--HO2S (oxygen sensor). The first thing to check would be the oxygen sensor and air filter. Then check the fuel pressure in the fuel manifold to check for fuel pump/filter/ pressure relief valve that may be causing an injector fault

OBD II P0172 Fuel System Too Rich (Bank 1).P0172 - System Too Rich (Bank 1) Essentially this DTC means that an oxygen sensor in bank 1 detected a rich condition.
When the code says that the Fuel System is "too rich," it means that the computer has been subtracting more and more fuel, which is called Long Term Fuel Trim. Ideally, the Long Term Fuel Trim should be close to 1 to 2 percent. When a code P0172 is set, it means that the Fuel Trim is anywhere from -15 percent to as low as -30 percent compensated. When this happens, the computer knows that there is an improper condition in the control of the Fuel System.


Thanks.
