John,

Just a quick aside to your post and normally we are happy to use NGK/NTK O2 sensors on most cars however, we have tried to use them several times on older Honda Accords (2000-2002) and the ECUs on these just refuse to work with them constantly setting heater DTCs despite the resistance between them and a genuine one only be negligible.

Of all the vehicles that these should work fine on you would have thought Honda's would be one of them, but no, only genuine ones will do when the heater side on them go open circuit.

Regards

Sean
