O2 Sensor

[Dave]

I have an 2001 miata with an engine code of P0037 wich is 1st bank 2nd heater o2 sensor. wich one is that? I think it's the second one back after the cadalitic converter. autoxone has one for $342.00 wich is OEM and says it is calibrated closer than the universal one for $70.00. Dose anyone know if there is a big enough differance between them. Also do you need a special tool to remove and install the new one.
Hope you all have a very merry christmass and a happy and safe new year.

The generic one will work. No special tools I just use an adjustable wrench. Good luck.

Would that O2 sensor be covered under your emissions warranty?
