Hello, My check engine light came on and the mechanic got this code.... P0172B ... Any ideas?? Google search turned up with nothing. Would low fuel or aftermarket intake cause this code?
P0172 - System to Rich (Bank 1) The Adaptive Fuel Strategy continuously monitors the fuel delivery hardware. The test fails when the adaptive fuel tables reach a lean calibrated limit. See Possible Causes for DTC P0171 See Diagnostic Aides for DTC P0171
That could just be because you drive a Focus. Is it boggier than usual?I will look into it today, there is also a major bog starting out in first gear.
