Check engine light on Code P 0037? Checked gas cap, did not remove the light? Any ideas.
Contrary to popular belief, the 'check engine' light isn't synonymous with a 'gas cap loose' light. In your case, P0037 refers to the heater circuit for the downstream sensor (after the cat) on the driver's side bank is showing a low voltage. This could be a problem with the O2 sensor itself, or with the wiring.
