2003 kia rio stating running too lean( bank 1) replaced ozygen sensor reset check engine light but still cannot get the car to complete the cycle so i can get it emmission tested again......been 4...


When you replace an O2 Sensor the mil lamp
goes out right away,no need to clear codes
Your car may not do that,don't know
Have you looked at scan tool data for fuel trim
or had a shop back probe all the O2 Sensors with
a scope
I test all parts before & new parts going in,don't learn
anything other wise, or you have your situation
You may still have codes there
You may have a Converter that is worn out & the new
sensor has little oxygen to work with !!!
You may have vacuum leaks or exhaust leaks before the sensors
My question is-- assuming a repair shop is in the mix
Are they not capable of the answers to the fix??

Can you clean knock sensor on 2003 kia rio


O2 sensors in general are not "cleanable". If they have failed than they are typically replaced.

Do you have a code for an O2 sensor? If so whats the code?

I have a 2002 kia rio the code that came up is p1166 how do i fix


P1166. Primary HO2S (No. 1) Heater System Electrical.

Replace O2 sensor. Iif it smells rich then you are getting too much fuel. You may have a problem with the fuel pressure regulator or a leaking fuel injector. This can also be caused by bad oxygen sensors.

Hops helps (remember to rate this answer).

SIR, 2002 KIA RIO CINCO MISSING REAL BAD


Odds are, the O2 sensor is just detecting an imbalance in the Air/Fuel ratio, therfor causing your O2 sensor code.

Start by changing your spark plug wires, if it hasn't been done in a while.

Where can I find a diagram that shows where the Oxygen sensor is on a 2002 Kia Rio?


The o2 sensor is located in the exhaust pipe. follow the exhaust down under the engine until you see a short cylinder with a nut shaped end sticking out, It will have a wire sticking out of it . The sensor will not point at the ground but up where no road debris would break if off. You wll need a special O2 sensor tool to remove it,about $15 or can be borrowed from some auto parts stores
