Hello
Fuel Pressure is at 35 PSI. Been having an MIL 41 (HO2 heater) code come on during idle. Used a different O2 sensor without any luck. My understanding is that the PSI should be 40ish. Could 35 PSI fuel pressure cause the 41 code to come on?
Everything external (fuel tank, bulb, lines) seem to be working fine. What could be causing a small drop on fuel pressure? Do I need to take apart the VST?
