it's code 1 a malfuction of the 02 sensor itself and code 41 a malfunction fo the o2 senor heater wires?

Thank my thought on it

the GSR uses positive voltage from the ECU to run the O2heater and the other side of the heater is grounded.
Pretty much every other h/a (from what I've seen) has the ECU grounding the heater to make it active and of course the other side of the heater is tied to power.

There is only so much you can check here and you need a Helms and multimeter to do it.

You've got the O2 heater section + 2 wires + the ECU.

First make sure the heater section isn't blown out - 15-40 ohms is spec.

Make sure your wires aren't open or shorted out.

One black wire is fed battery voltage - the other wire goes to the ECU. Check to see if there is battery voltage on one wire - check to make sure the other black wire is going to the correct spot on the ECU/jumper harness.

If the O2 checks out and the wiring looks good - substitute an ECU. Yes, the heater control circuitry inside the ECU can foul up.

EDIT: OH - didn't know that about the GS-R and its O2 heater control strategy- my Civic uses the above strategy (supplied +12v with ECU controlling the ground).

no, only that your O2 is probibly wired wrong.

&gt;&gt;&gt;And wha tis the o2 heater??&lt;&lt;&lt;

Honda O2 sensors have 4 wires, the heater wire helps to heat the sensor up more quickly when you first start the engine. This wire will carry much higher power than the actual sensing wire which has to be extremely sensitive to small changes in voltages. The hardest part most of the time is figuring out which wire is which... and also which pin it hooks up to in the harness if you're doing the wiring yourself.
I don't claim to be an expert in any more than just plain definitions. Hope it helps.
