I have an 2002 accord ex with a CEL on and is showing code p0133 which is the front sensor closest to the cylinder head. Looking around here and online and the honda stealer I have a range in brands and prices to choose from? On the high end $200+ for Honda OE and then Denso, Bosch and a few others. Anyone have any thoughts and best place to buy? Also can someone tell me what generation my car is and how to tell what engine I have and if it's a ULEV or just the LEV?

 

I'd assume Denso is actually the oem supplier, though not sure. That would be my first choice, and their prices tend to be decent. If you stay away from the universal ones you should be fine.

Might check www.hondaautomotiveparts.com to see if you can save anything significant on the oem part.

I believe yours is a 7th gen.

 

Bosch did not work on my 93 accord. NTK fixed my issues.

both NGK or NTK should work fine as long as you get the right sensor and it's a direct plugin replacement and not a universal reuse your old plug cheepo...and ULEV and LEV are not interchangeable , the only way to know which one you have is to pop the hood and look on the motor it will say on the valve cover.

 

I ran some fuel injector cleaner techron in every other full tank for 4 tanks and now everything is working fine and the cel has gone off and not come on.. So far so good..

 

Denso is your best bet. OEM supplier.
