P1174 Determines if the air-fueldelivery system isimbalanced by monitoringthe pre-catalyst O2 sensor

voltage characteristics

The Bank 1 AFIM Filtered Length Ratio(EWMA) variable exceeds a value of0.173.

Notes:1. The AFIM Filtered Length Ratio isdetermined by calculating thedifference between themeasured O2 voltage length(accumulated O2 voltage over a2.5 second period) and anemissions-correlated thresholdvalue, divided by the thresholdvalue, and finally multiplied by aQuality Factor (the latter ranges

between 0 and 1, based onrobustness to false diagnosis inthe current operating region).The resulting ratio is thenfiltered utilizing anExponentially Weighted MovingAverage (EWMA).

2. The first report is delayed for 25seconds to allow time for theAFIM Filtered Length Ratiovariable to saturate. This

minimizes the possibility ofreporting a pass before apotential failure could bedetected.
