Help me get my CEL off....41 Primary oxygen sensor heater
Well i have CEL 41 Primary oxygen sensor heater
and i not really sure where this is on my engine.... and is it whats causing my car to idle low... and even stall sometimes?
I searched and found this... and also in the manual i found this but i still lost...
Engine is b20z, with b18 ecu

If the crack in your exhaust manifold permits outside air to mix with the exhaust gas, then even a good O2 sensor will not send the correct signal to the ECU.
By the way, code P0135 actually indicates a problem with the heater component of the O2 sensor or the circuit for the heater:

Primary oxygen sensor is the one closest to the engine, before the catalytic converter.
If the sensor ohms are OK but you don't get the voltage in the test near the bottom of the first page, check the harness for damage (the fuse 15 problem).

ok the sensor is in, but is not connected to anything .... its just like 5 wires sticking out of the sensor... what should i do with that... and when i was under i also realized a plug coming down from intake manifold wasnt plugged into anything... Dam it lol

Edit: Do you have an OBDI ECU? If so, check the primary O2 sensor and its wiring. The code is for the O2 sensor heater element or its wiring.

In the picture, it looks like the secondary O2 sensor is disconnected, which would be tolerated by an OBDI ECU.

You need to provide more information about your engine problem; however, fix the primary O2 sensor code and try cleaning the IACV for a low idle problem. Are your plugs, wires, cap, and rotor in excellent condition?

the previous owner said that they are all in good condition..
and imma clean IACV here in a bit...
but the engine problem im having is this.
Sometimes my car will start right up no problem but when you FIRST start it, it always idles real low and wants to die... i just tap the gas for bout ten seconds than its all good from there out till the next time i start it..
but if i dont tap the gas and let it die than it will not start back up unless i give it full gas while its cranking than it starts up REALLY slow and rough
