What is the primary oxygen sensor heater? I know that there are other codes that are just for the oxygen sensor. but my sensor is plugged up. what does this code mean? thanks!

 

?bump

 

it means that the heater element of the primary O2 has gone bad (or you have a wiring problem)
if you have an ohm meter measure the resistance between the two black wires, it should not be open or more than 1k ohms. If it is more than 1k ohms replace the O2 sensor.

 

Get a new o2, it will be best. By the way what size socket to hv this taken off?????????

I finally got my new o2 off the net.

It did take a week, called em , it was back ordered,
but anyway. Got the part, 2 days later went to work on it.

Opening was <U>very simple</U>, but make sure you use lubrication <U></U>a
day b4 and spray it good.

Took me 1/2 and hour to get it done. I took the bad out, tried to clean it, put it back, cel was on. Put ther new o2, ran for few minutes, took for test drive, all was good.

Problem finally solved. <U>Dealer charging $350</U>, haha, forget them. Local repair shop, $100 withought the part.

If you know what ur doing, it's not a big deal.

Either way, car has been running fine, no troubles detected. [/IMG][IMG][/IMG]

Tonight I have to do a regualr tune up...

By the way, the sockect size is the <U>22mm</U>............
