I have a 2001 SL1 and it was throwing P0037 & P0041 codes. Have been searching online and have so far done the following:
Replaced both O2 sensors
Checked the relay for air pump
Checked all vacuum lines for leaking and being disconnected
Checked coolant sensor and connector for corrosion
Cleaned throttle body and intake with carb cleaner
Checked intake manifold gasket for leaks
It now just throws a P0037 code but it stalls when cold and the idle just goes where it wants to. Any help would be appreciated!! Thanks!!
Thanks but the description for this code is HO2Bank 1 Sen 2 Heater Circuit Low. which should be the o2 sensor and I have already replaced both of them. I'm kinda stuck
