P0113 Ford - focus

Question

Try to get the 2000 ford focus inspected and it failed to a P0113 code. The car does have a rough idle and the gas mileage inst like it use to be. Any help on a fix would be great.

Answer 1

P0113 Intake air temperature  (IAT) sensor circuit high input

The IAT is part of the MAF (mass airflow) it is  not seperate from the MAF unit, the IAT by itself does not cause much of a idle difference. The rough idle is also seperate from P0113. The job for the ECM is to look for open circuit (which are circuit high) grounded circuit, and short circuit, The ECM is also capable of suspending other code conditions until a open circuit is corrected. Fixing the MAF do not be surprised if another code appears . this may help point why the rough idle.
