P0172 I believe it was. On my friends 06 Jeep. What and where should I check first? I guess running rich is better than lean, but you're burning up a little more gas.... |

Pretty good explanation here and troubleshooting tips for that code: P0172 |
|
A rich air/fuel mixture has been indicated by an abnormally lean correction factor. Was the fuel pressure checked with a DRBIII pressure transducer? Is the fuel pressure within specification with engine running at normal operating temperature? Verify the correct DRBIII PEP module pressure transducer is being used It is critical when reading pressures with the DRBIII PEP module pressure transducers that the proper transducer is being used. A too high of value transducer will cause inaccurate readings. It is also critical that the DRBIII and pressure transducer is zeroed out before taking a reading.Repair or replace any fuel system malfunctioning components |
Wouldn't fuel pressure affect both banks? If it is a 4 cylinder, then it could be. Too little info to tell. |
