Question about 1999 Ford Explorer
The following are the codes you have given me:
PO102 - MAF sensor - Low voltage input getting to the MAF sensor which is the signal it is receiving from the CCM.
1. MAF not disconnected
2. MAF has voltage to it from CCM
3. Intake air leak close to MAF
4. A faulty Throttle Position Sensor
5. Damaged MAF sensor
6. Faulty PCM
PO113 - Intake Air Tempreture Circut - High Voltage input
1. Open circut in harness
2. Sensor signal is shorting
3. Damaged Sensor
4. Improper harness connection
5. Paulty PCM
PO171 - System is to lean in bank 1
This will be caused from the 2 previous faults.
PO302 - Misfire Detection Monitor
2. Fuel injectors
3. Low fuel
4. EVAP canister purge valve
5. Fuel pressure
Check the easier faults first then start looking at the more difficult if the main systems check out, hope this helps let me know if you need more information.
