P0104 - Mass or Volume Air Flow A Circuit Intermittent/Erratic Description: A concern exists in the mass air flow (MAF) sensor A circuit, or the air tube containing the sensor, causing an incorrect air flow reading. Possible Causes: Intermittent circuit A open or short Air leaks in the tube from the MAF to the throttle body Diagnostic Aids: Description. corrplot (X) creates a matrix of plots showing correlations among pairs of variables in X. Histograms of the variables appear along the matrix diagonal; scatter plots of variable pairs appear in the off diagonal. The slopes of the least-squares reference lines in the scatter plots are equal to the displayed correlation coefficients.
