Hi I brought the car to the shop to get this installed just to be safe.. They told me that they wouldn't be responsible if something happened though so I just want to be sure, that hooking this up to the fuel pump positive 12v power source is the wire to go with=?

Also, the guy told me that this thing will stay on all the time (when the car is running) so he said that he wasn't responsible if it overheated or caused a fire. Is that even possible with this? He mentioned that newer cars cycle the heat on or off via the ECM (I suppose when the ECM detects the sensor is getting to a low temp is turns the heat back on.) Would this be an issue or is keeping the O2 sensor on at all times okay to do?

Also, my Edelbrock headers have the smog provision blocked off (AIR system was removed). Doesn't seem to be a leak but I'll double check just to be sure.. Thanks!

 

Heat all the time while the engine is running isn't a problem.

 

This will be fine, its a heated oxygen sensor, its supposed to stay on all the time when the engines running. You should know this, but I guess thats why your paying someone else for a 5 minute job.

I've had mine, in my car, on for over 2500 miles, no problems. Go to my youtube cronsformula350 and see what you think. The fuel pump can pull up to 10 amps if it needs too, the 02 sensor doesn't use a lot of amperage, it uses watts of power. So it won't damage your wiring, or the relay, your only using 1 positive wire. U'd be more worried if you used the fans for the engine, off one wire. The o2 will be fine, why are you questioning it? DO it! You know how many guys do this? Tons!

 

lol thanks for the response! I'm just like that :P get nervous when dealing with wiring and things like that. The car is already in the shop so I would just have them do it while it's there, it's just more convenient for me to have them do it..

I'll get it done lol thanks!

 

I have the Bosch 13077 wire and it has 1 black wire and 2 white wires, from what I have been reading the black wire is the "sensor" wire for the ECM and the other 2 white wires (one is ground and the other is power) Is that correct?

 

Yeah thats all you need. My recent trouble was my ecm 10 amp dual wires breaking free from my 10 amp fuse on the back side of the fuse panel, well it is 132K now, even though I only put 9441 on her so far, mileage happens.

I might try running your o2 sensor, the heated one off its own relay to get it even hotter maybe faster. Mine works good in about 2 minutes, but maybe try seeing if it will heat up faster on its own dedicated circuit. I've had mine running off that (+) from the fuel pump relay for at least 7000 now with no problems, but there may be a better way, just sayin

 

So on the 2 wires it doesn't mater which is power and which is ground?

 

Correct. The heater circuit is completely isolated from the sensor circuit (doesnt ground through the pipe), basically like a light bulb, hook it up backwards and it'll still work.

 

I'm in the process of putting on some hooker 2055 headers and saw this thread regarding the heated o2 sensor and it looks like a good idea. I have the stock o2 sensor right now and was going to hook that up until I got the Casper retrofit kit from Summit.

Seems like the wire is too short on the original sensor though for the new location of the bung. Would it hurt the performance of the sensor if I crimped on some wire to extend it to the new location or no?

 

If you want to still use the original wire and it won't reach just cut it in half and solder in a piece of wire to make it the right length. I'm running shorty headers on mine with the original 02 sensor and it will come out of closed loop at idle so I'm switching it out for a heated sensor. But, if you want to get by with what you have for now just lengthen the wire. I would solder the connections though and not use butt connectors.

 

Thanks, I will try that after I go to pick up some more wire. What heated sensor are you going with?

 

I got the bosch three wire from tpis.com it was in my mailbox 2 days after placing the order. I'm putting it in tomorrow. I've got shorty headers with the 02 sensor in the collector bung hole. If I idle the car up to 1000rpm it will go into closed loop. But, when I take my foot of the gas and let it idle it will go back into open loop within a couple seconds. So the 3 wire 02 sensor should keep that from happening. It probably wouldn't hurt anything under normal driving conditions but, I would rather it stay in closed loop at a traffic light rather than coming out every time I come to an idle. Hope your project goes good.

 

Big waste of money.

 

Here is a thread of mine from 2008 when I did mine. It has the P/Ns I used and pics of the install:

https://www.thirdgen.org/forums/tech...heated-o2.html

It made a huge difference where I was living in CA at the time in the winter. With my headers that would not hold enough heat (no header wrap) having the heated o2 was great. Plus the Denso sensor I used a FINALLY consistant when it came to my custom running. I will NEVER, EVER run a Bosch piece of crap o2 again.

 

I installed my three wire 02 sensor yesterday from Tpis.com and it worked perfectly. Once it went into closed loop it stayed there. Before it would come out of closed loop at idle so I'm a happy camper.

 

Yes, I think I may go a different route and return this..

I was taking a look at your thread and think I'm going to go this route instead.


Good to hear!
