My banks IQ tuner tells me that my " Ecm Detects voltage on the IAH (Intake Air heater?) circuit when the relay is commanded OFF, or incorrect voltage when the relay is commanded ON.


can you guys tell me what exactly this means? my dads shop computer said the IAH stands for intake air heater? not sure if that is totally correct?


Cody p.s. im sick of seeing my engine light on b/c of this lol help please! :):help

unplug your banks, shut the ignition off and let it sit for 15 minutes. restart without the banks and see if you are still getting the code. that will eliminate the banks IQ tuner.
