| Windstar with 3.8L Engine | 1.43 gm/sec | 1.64 gm/sec | 2.58 gm/sec | 7.53 gm/sec |
NOTE: To use this table, connect a Scan Tool and select the MAF PID. Read the value and then compare it against the known good grams per second (gm/sec) reading for the vehicle and engine in this table. A faulty MAF sensor will read out of normal range.
