Answer
What you are referring to is the IAT (intake Air Temp) sensor.

Your problem is that you are getting more fuel to one side of the engine than the other and is NOT caused by the IAT.

Faults could be:

faulty fuel injectors, Cracked or fouled spark plugs, Cracked/ leaking exhaust manifolds or exhaust pipes, Leak in the intake manifold.



Are you getting any OTHER CODES ?.

Do you have an engine miss, lack of power or poor fuel economy ?.
