P0113 Ford - explorer 1998

Question

I have just changed the o2 sensors (both) trying to get rid of cel saying running lean both banks, now I get PO113 IAT Sensor 1 circuit high input

Answer 1

Hi there,

This may be the problem causing the lean codes. Since it was lean on both banks it usually indicates something that affects the fuel mixture on both banks. A faulty IAT sensor would cause or could cause a lean fuel mixture.
