Code 1 = Oxygen Sensor A (primary) defective circuit or unplugged/ defective sensor

Code 43 =Fuel Supply Ssytem defective or malfunction in the fuel supply system.

Okay, what now?
Seems like both related to Oxy Sensor.
Should I just replace them?

Please help.....I can diagnose...but not sure what to do afterwords! :-)

 

most of the time the ox sensor will cause the 2 codes that you have. replace the sensor

 

thanks for the reply....one more question.
I have been reading some of the other post in here, and have read something along the lines of "mixture is to rich"....i'm not a mechanic, but I believe that has something to do with to much gas not enoug oxygen. Could this also be a problem? If so, how is that fixed.

Lastly, can this be caused by clogged fuel injectors? I'm thinking of going and buying a couple of bottles of inector cleaner and seeing if this helps.

Thanks!

 

hey i thought code 41 was the o2 sensor.
anyway. when the o2 sensor i fucked this will cause the car to burn rich. meaning it burns a lot of guys. it will burn gas as a ******* v6.

so change the o2 and clear the codes and check if u get other codes again.

 

code 41 is O2 sensor heater

 

where is located the o2 sensor?


i tought i was on the header or catalitic converter ???


any body has pics if it is the one i thinking not need the pics but if its not will need pics

 

Depends what year car and what trim level (LX, DX, EX, SE) your car is.

If its an EX, its gonna be under the car near the cat, otherwise it will be in front of the radiator on the header.
