I am getting a p0704 code and a lean bank 1 -1 code. The clutch (p0704) sensor came disconected. I also scanned the o2 sensors and they were all in normal range after I replaced the clutch switch. Should I still replace the bank 1 o2? How hard is it to replace? Could the p0704 code make the o2 read as lean?

 

O2 sensors are easy to replace, but do both for peace of mind.
Are they "switching" ok?

 

What do you mean by switching ok. All of the other ones seem to be within normal range except that one, but like i said after replacing the clutch switch we hooked the scanner back up and they were all within normal range unless an O2 can sometimes read ok and sometime read bad

Dunno??

 

During closed loop they should "switch" or toggle above and below a hinge point like 450mV.

 

Where can I get them at the best price AutoZone has them for 70 bucks a piece?

Also, I do not have access to a lift so is the somthing that easy laying on my back in my driveway?

 

Any Input

 

yeah there pretty easy to change especially if you have long tubes, i think i can change mine without even lifting the car. if you plan on getting long tubes, get the corvette rear o2 sensor from autozone, it has an extended wire so you dont have to buy $25+ o2 extensions, plus it has a better heater so you dont get the o2 heater codes.
