while do i get codes p0113 &p1504

Question

i did an eng.check and gets these two codes po113-p1504

Answer 1

HI there,
The first code is for a intake air temp sensor. This could be causing the second code, which is for the idle control. IF the engine is searching at idle it will cause the P1504, but if it's not getting the right info from the IAT then it could be causing the searching. Clear the codes and replace the IAT sensor. If the IAC code returns, then clean that.
