Help - Cel Code 41 - Primary O2 Sensor - Heater Circuit Malfunc.
My buddies 97' Civic is throwing a CEL 41 code.. 41 says "Primary Oxygen Sensor - Heater Circuit Malfunction".
Does just mean that the O2 sensor needs to be replaced?

Not throwing any other codes? A PO2S shouldn't cause the stalling problem.. for the heater circuit especially.. at least I can't see why it would.

Sounds like a bad O2. If the ECU can't get a reading it'll go full rich.

Do the codes come in a series or do you have to turn off the ignition and repeat to get all the codes?
