NEED HELP - '01 ITR - P0132 code
Hey guys I need some help I've been trying to diagnose a problem with my ITR.
'01 Integra Type R, virginly stock.
Here's what is going on:
- Randomly threw a P0132 code
- Drove a few miles with the light on, car bucked and hesitated a few times.
Here's what I have done:
- Checked code with NAPA's bullshit scanner, before making a 1 hour drive to my dads shop.
- Mac Tools scanner checked the code again, still a P0132.
- Read the data stream with car running, o2 sensor locked at 1.25 volts.
- Replace o2 sensor with a NGT brand from NAPA.
- Another tech put a 7,000 dollar snap on scanner on it and said the mac tools scanner was locking the reading in, on the new scanner I saw it fluctuating from 0.8-1.6 volts and when the car is shut down it shoots up to 3.89 volts.
- He seems to think the ECU might have been damaged when the o2 sensor went bad, like it short circuited and sent power back to the ECU the wrong way.
- I also checked the wiring harness under the intake manifold from both the top and from under the car on a lift. No exposed wires, the wire loom doesn't appear burnt or damaged.
- I unplugged the ECU let it sit, 2 minutes later CEL.
Anyone have ideas?

Re: NEED HELP - '01 ITR - P0132 code
My post was very valid. The sensor was replaced and nothing seems to have changed, which says that the original sensor was not defective. Or the story was explained poorly so I'm drawing the wrong conclusion, which is always a possibility.
The conclusion that the original sensor was bad was based on an incorrect scanner reading, and the new sensor was read with a different scanner. So it's completely unclear whether the problem was the sensor or the Mac scanner. That makes the whole troubleshooting process break down because you're changing multiple unknowns at the same time, but I digress.

You've been here since 2009 and I've never seen your name on this forum before (I don't go into the For Sale forums) so I had to check things out.

The MAC scanner was locked to the reading from the original o2 sensor upon scanning the datastream
for the 2nd o2 sensor I installed (the one in the car now).
Both the old and new o2 sensor are giving the same bizzark readings.
I feel like the original o2 sensor was bad because it wasn't fluctuating from 1.25volts..

Re: NEED HELP - '01 ITR - P0132 code
come in my thread and spread your ignorance than it would have taken for you
to go on about your business, or log out, the latter of the two would probably be
best.
