My car is a 2000 vtech honda civic. Engine light stays on even after I took the car to the mechanic and changed the oxygen sensor, which they said was the problem. I took it to another place and I am told that the problem is with the manufacturer control fuel air meatering. What does that mean, please? What should I do next? My mechanic does not seem to know what to do. THANKS

This code does not mean to replace the sensor , testing is what is suppose to happen .

n evap leak has nothing to do with an oxygen sensor issue. What is your error code that you have now?

theres only one catalytic converter. but it should be refering to the oxygen sensors. if your going to change them, you should change all of them, but since i can imagine money is an issue right now in this economy, change the front one, its the main one, and the one towards the rear is the back-up one. hope this helps, goodluck.

SMOKE DETECTOR?????? Take it to HONDA and stay away from MIDAS of any other chain store.

Disassemble and clean the carb, particularly the jets. I suspect the charge light being on is a result of your destroyed battery, which needs to be replaced. Sta-bil over the winter and a smart trickle charger will prevent the problems you are having in the future...

thank u

rate me!!

It might be bad gas or a plugged filter or it might be a bad mass airflow sensor.

P0041 Downstream Oxygen Sensors Swapped From Bank To Bank
How does a P0041 code trigger the check engine light? This code will trigger the light to come on under the following condition:

The Heated Oxygen Sensor Monitor, a strategy built into the computer, determines if the Heated Oxygen Sensor (HO2S) signal response for a change in fuel trim corresponds to the correct engine bank. If a response from the Oxygen Sensor being tested is not indicated, a trouble code will be set and the MIL (Malfunction Indicator Lamp) will illuminate.
Possible Causes:
Crossed Heated Oxygen Sensor harness connectors
Wiring swapped from one Oxygen Sensor connector to the other
Wiring changed at the computer connection or in the related harness

remove brackett from under intake manifold to block you will see a gray or green plug look real close and you will see a bare wire or a wire that has been pinched real bad this wire controls heater circuit for the o2 sensors also check fuse # 15.there is a tsb from honda on this problem

both are located in the exhaust system. You have to get the car off the ground and follw pipes. You cant miss the O2 sensors.

check your fuel pump and fuel filters you might need to chage it.
also check your air filters change it if necessary
