chekc engine light driving me nutZZ

[luxor]

hello all, i have a 96 4runner that i have spent over $300 trying to fix so i can pass the smog check..i get this messege (O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) and i have changed both oxygen sensors on it (the one by the manifold was spliced and a 2001 sensor used) new catalytic converter, new fuel filter and new air filter but the check engine light will not go away and that messege keeps on coming up when i do the diagnostic with my obdII. Is there someone out there that could help me with this one cause frankly i feel like driving that piece of junk of a cliff but it is the only car i own,,your help will be greatly appreciated....thanks!!!

Its a fine vehicle...not a piece of junk. Have you smogged it since you did this work...that light just might have been shut off. If not...check your valves...if the timing is off...there ya go.

I think u have a air fuel ratio sensor in the place of the o2 I think that 2001 model uses airfuel ratio sensors in bank1 sensor1 and that may be the cause of your check engine light.

Thank you TRDCivicCrusher I will check it out...does anyone know where I can get an oxygen sensor for a descent price. I have been given quotes as high as 500 dollars. That is ridiculous and I can't afford that spend that amount. your help is greatly appreciated.

I would also put a description of your original problem out on the following forum in the discussion group:

I have seen several questions on 02 sensors there plus the best places to purchase them. I'm sure that someone will respond quickly.

o2 sensor for a 96 4runner just to try it out and that actually
