ok guys this is what is going on, i have been fighting with this all week i have pulled the codes i have a 1001 code wich is the Front Left Htd 02 sensor heater and also a 0401 code wich is Intake Air Temp Sensor wich i tested and seems to be working fine i also have a KS code and a 0503 wich is a Front Right Heated O2 sensor. i dont know what to do , is there a way to test the 02 sensors . i need help guys . if anyone lives in mass and wants to help give me a PM other wise just help me on the .org.

 

this is just a bump help

 

replace the o2 sensors.

 

Did you check the voltage of them with a multi meter?? Check your haynes manual for reading numbers, if there off replace, if not somethig else is the problem.

Did you change teh intake temp sensor? It might be the culrpit of the other codes.

 

i did check the V with a V meter but i cant seem to get a reading from it , i dont know if i have them on the right wires there are 2 white ones a one black one

 

I would replace the knock sensor first.....Many times a faulty knock sensor can cause false codes to be thrown at ya by your ECU. I'm sure other .ORG'ers will agree.

 

YES REPLACE THE KNOCK SENSOR PLEASE!!!!!!!!!!other wise u will be wasting hundreds of dollars on other nonsense.....maximabebe is right....the knock sensor sends false codes to the ecu.common false codes include MAF, O2 sensor(s), air temperature sensor, and sometimes even the cam sensor.
replace the knock sensor.....cheapest one i've seen was the one listed up here for 110....i paid 159 for mine cuz i was so fed up with the codes and the CEL.
hope i was of some help
