I have the 1.6 unfortunately. The reason I am messing with the wires is because I am trying to get rid of a P1141 code (rear O2 sensor heater low voltage). This has nothing to do with the excessive flow codes.
I was able to use this guide to get rid of the excessive flow code, however in the...
WOW DO NOT TRY IT. The resistor got too hot and then started flaming. I had in wired up on alligator clips on the outside of my car and it burned my left turn signal light. =(
Then as I was try to blow it out and move it to somewhere where it couldn't burn my car, the two wires touched and my...
I haven't tried it yet. I got LASIK two weeks ago and have been taking it easy. I'll let you know when I do it though. I already picked up a pack of 15ohm resistors at radio shack.
Hey guys, I finally got around to testing my O2 sensor and I found out the code I am getting is inaccurate: "Heater Circuit Low Input". I am getting NO input (but there is no OBDII code for this). There is no continuity between the C and D terminals (the black wires)
So it looks like the heater...
So what I've been able to learn so far is that the O2 sensor has a heater in it that is supposed to heat up the sensor faster so the the engine can run in closed loop mode. I removed the non-fouler closest to the header because I thought having the sensor closer to the exhaust stream might make...

I disconnected the negative terminal for 5 hours or so. I also deleted the code with the OBD scanner after it popped up and it came back that way too. I think the condition that triggers it is that the car experiences the same problem consecutively during two "starts" of the car.
The car was off for 5 hours (so I'm pretty sure the ECU was reset) and the CEL was off when I turned it back on. I backed my car into the garage and when I drove out later, it showed up within ten minutes.
Thanks for all your advice everyone!
Everything is snug. Low voltage input probably means that the O2 sensor is detecting less oxygen as a result of pulling out the sensor a little right? What if I drilled a slightly bigger hole into the first non-fouler so more air got in?
I don't know if it matters, but I am using an 1.6L OBX...
Yes I drilled it completely through.
Yes this was for the second O2 sensor.
No I made sure none of the wires were twisted.
The battery was unplugged for 5 hours.
=( I spent 6 hours removing my seized O2, did the non-fouler method and now I am getting P1141: H02S Bank 1 sensor 2 Heater Circuit Low Input.
Any ideas? Maybe I should remove one of the non-foulers (the undrilled one)?
Please help! I put the 1 megaohm resister inline on the blue wire and now I am getting P0140 DTC: HO2S (rear) circuit no activity detected. "If input voltage from sensor never exceeds .55 V for 30 seconds, PCM determines that sensor is not activated." I checked the connections and it is nice and...
Brilliant! I had rough idle for about 10k miles (68K total right now) and following the guide helped get rid of it! Either that or resetting the ECU helped a lot...
Anyway, I have a 1.6L ZM-DE engine and I took a couple pictures to help other 1.6's find and clean their car. Sorry about the...
Hey guys, I got mine installed on Sunday. The extra power is definitely noticible and it feels great! I can't believe how bad the original header design was...
No problems with the install, but was the header supposed to change colors?
