O2 sensor, I did something stupid..
O2 sensor, I did something stupid..
Hi Folks,
I was installing new Oxygen sensors earlier today. I got interrupted and
installed
them with the protective plastic caps still on,duh. I didn't even realize my
mistake
until I pulled out to test drive. I got a block from my house and the engine
stumbled.
I thought it was just because it was cold, but it never did that before. It
took a couple more blocks before it dawned on me going over it in my head,
I'd left the protective
plastic caps on. At that point wtf, I'll drive around and burn 'em off not
much choice at that point. Plastic is a hydrocarbon after all. I'd guess it
would just burn off, I hoped. It seemed to do just
that. After less than a couple miles, she was running well. Can any experts
out there tell me if
I have destroyed the sensors. Can I test them somehow? Do I need to? I know
certain silicates in coolant and some silicone sealers kill O2 sensors but I
wouldn't think that hydrocarbon plastic
would do so. I would think it would burn right off and not hurt the
catalytic converters either. Any techs out there with a minor in chem,:>). A
little info would help assuage my guilt over this,Adysthemic

Re: O2 sensor, I did something stupid..
I don't think that is even physically possible.
I have just replaced the O2 sensors on a car and the plastic cover
covers and protects both the sensor and the threads, so it is
physically impossible to install these sensors with the cap on.
So unless your caps are very different from the ones Bosch uses on
their sensors, you did not leave the caps on.
The problem is probably that the ECU is adapting to the new sensors
which will take a while. It would probably be quicker if you can clear
the adaptive memory, possibly by disconnecting the battery for a few
minutes.

Thomas,
You were quite correct. The car ran poorly due to the fact I had forgotten
to plug
the connection in that heats the sensors. The protection caps I found in my
pants
pocket this morning. The were indeed Bosch and could not have been left on.
Funny how one's mind get carried away and makes incorrect assumptions. Good
thing I'm not a detective ;>).Adysthemic

How did you manage that? The two heater wires are usually an integral
part of the 3- or 4-wire plug, along with signal and ground, and are not
normally removed, unless you took the plug apart or bought some
"universal" sensors that needed to be soldered to the old plug.

Converted from single wire to 3 wire. Pre-wired the circuit last week. Just
forgot to plug in the bullet connector that powers the o2 heaters.
