Question about 2001 Ford Explorer Sport Trac
1. At the Mass Air Flow (MAF) sensor connector, backprobe the Gray (GY) wire at terminal #6 with the key on and the MAF sensor connected. Typical voltage will be about 2-3.5v depending on temperature.
2. If the voltage is above 4.5v (which is what the code P0113 indicates) check the voltage on the Gray/Red (GY/RD) wire at terminal #1 of the MAF sensor connector. The voltage on the GY/RD should be less than about 0.1v.
3. If the GY/RD wire shows less than 0.1v and the voltage on the GY wire is above 4.5v, inspect the connections at the MAF sensor connector. If OK, replace the MAF sensor for the open Intake Air Temperature (IAT) Sensor.
4. If the voltage on the GY/RD wire shows above 0.1v, locate and repair the high resistance between the MAF sensor and pin #91 of the Powertrain Control Module (PCM) connector.
5. If the voltage on the GY wire is not above 4.5v but the scanner shows -40 F on the data stream, check the voltage at pin 39 of the PCM. If the voltage at the PCM is above 4.5v, locate and repair the high resistance or open circuit in the GY wire between the PCM and MAF sensor connector
