Oxygen Sensor Heater (Secondary)
malfunctioning or defective oxygen sensor heater

car is a automatic 2000 accord Lx sedan. anybody know where that's located at? this is the code i got. 67

 

It is located on the exhaust piping. follow down from manifold toward the catilytic converter. I don't know if there is one or two on that model, lx usually has just one.

Of course there are. Did you doubt it? Look on the exhaust I guarantee you will find at least one.

sorry.... i meant there are 2... the primary... and a secondary?

 

There may be two, I'm not sure about your year. You would have to get under there and check it out. Unless you have a repair manual. Which, by the way is a good idea. Get one. Preferably helm (it's the one factory techs use)

 

If you look it up on one of the on-line parts stores it might say secondary and primary, or something to that effect.

 

The 2000 Accord is equipped with an OBD2 Engine Management system (first seen in the 5th Gen Accords). It requires two O2 sensors. A primary one ahead of the converter, and one behind. The O2 Sensor heater is incorporated in the sensor itself, and is traditionally found in the second (#2) sensor position. It can be recognized by three wires that run to it. Two for the sensor operation, and the third for the heater.
If it set a hard code, you'll have to replace it.

so what you're saying is there are '2' sensors.. one behind the cat and one before it. because that is what i see... and im getting code 67.

 

I think that's what the man said, and he is an expert. I'm not.

 

Yes, in every language I can think of........
