Do you notice any odd running issues with the vehicle?
How many miles do you have?
The wrench light in most all cases indicates a concern with the electronic throttle body plate sticking or not moveing well. You really need to get scan tool hooked up and retrieve the codes stored in the PCM so you know for sure where to begin diag or what to replace. I suggest you first off do this fuel system service shown below exactly and then see if the concern re-occurs.
You do have a electronic throttle body.
You can rent or buy a scan tool from most parts stores. Or pay a shop to scan it.
The MAF and IAT sensor are one part mounted in the air intake tube between the air filter and throttle body.
