Hey lads, my mate has a 2007 2.0 rx non turbo with codes p0030 and p0037 both relating to low heater circuits, when testing both sensors there is resistance between the heater wires on both sensors. The alternator appears to be failing as the headlights and interior lights flicker on idle as well as a screaching alternator. seeing as it's two separate sensors with the same problem and one is brand new. could the low voltage of the car be causing the low circuits codes for both sensors as they are mostly likely receiving less than 12v if the rest of the electronics seem to be struggling with power. Cel on only those two codes and no battery light on dash
Thanks in advance
