Some of you know that my iQ is a salvage car and I will have to fix everything, file all the paperwork correctly and pass the tests. I would like to drive the car to the New York Anti-Theft exam. I am allowed to if I ask for the permit and send a proof of passed smog and safety test. Well, how do you get all of the readiness monitors to say "ok" if you can't drive the car? Possibly the garage can give me a pass so I can drive the drive cycles, except I have no plates, so that is out. I have Cat, 02S, Heater still out, as well as Evap, but that one doesn't matter.

My ODB2 tool shows me that the first O2 sensor is fine and I see it quite active on the tool. The second O2 sensor is not active, but possibly the hasn't gotten warm enough yet. I also have a leak in the exhaust near that first joint which is before the second O2. I'll just have to fix that because it's also noisy and annoying. I have nice illustrated drive cycles for the 3 missing readiness monitors.

So, I will put the car on jack stands and do the drive cycles. This has worked for other people with other cars. I don't know if it will work for me. I don't know if traction control or abs will get in the way. A four wheel dyno or a big closed loop track would be better.

You might need the gasket, part number 17451-f2010. About $18 plus shipping. ;)

I would trace and test the wiring from the ECU to the 2nd O2 sensor to make sure it's all intact. You can try it with a multimeter and then try it with a low amp load (1156 bulb would work) to ensure the wiring can handle the load. You should be able to remove O2 sensor and inspect it fer any issues. When in doubt, you could always replace it with new. ;)

One option is to tow the vehicle to a rural area and go fer a drive. If everything is working correctly, it shouldn't take long/many miles to set all of the remaining monitors. ;)

Maybe you can get a temporary 'in the works' permit? I think we have something like that in our state. I recall most of the monitors can be ready in a single drive cycle if you follow the pattern. However, the last of the monitors (unfortunately don't remember which on - may be it was indeed the O2?) just would not come up as ready. It did become ready either when I drove it next day, or the same day after I let it sit for a few hours. The point is, it might be expecting a few "trips", so if you have time - try the same drive pattern the next day as well.

As well the sensor itself goes - you can hook up a cheap ELM ODBII dongle and watch inputs from all sensors in the car in real time on a phone app. I think that should at least give you an idea if it works or not. If you can't get it to work - let us know. I can try watching the O2 and confirm it does send data to the app. I have a vague recollection there is only one O2 sensor (donwstream) on IQ - it sits right on the exhaust header and you should be able to see it when looking under the car.

EDIT: I take it back. Looked into the engine bay. We do have two O2s as usual.

I will get the donut and manifold gasket. I have my manifold/converter off. There is a hole before the flange that you can stick a pencil in. I'll weld that up. I found a boss that looks like maybe air injection. We don't have air injection. The part of the boss inside the pipe is maybe 3/8 of an inch and goes almost all the way across. This might fall off, and it's lucky I can weld up the hole.

I replaced the 2nd O2 sensor because it was mangled either in the flood or at the auction. There is one bit of wire harness that gives me trouble. Sometimes the battery light comes on even when it it charging just fine, new battery and alt. It is a part of the engine harness that goes to the fuse box to some module, next to the ground cable. It has a white connector and a black one, both go to that module. I have schematics.

New York doesn't have that. Without plates, I don't think I'll try that first. First I will fix the exhaust leaks and then make sure electrical is right. I have the Elm Bluetooth thing. I can see the live data for both O2s. I'm guessing I'll know when the second O2 decides to work.

Maybe you can get a temporary 'in the works' permit?

Holes in the catalytic converter pipe, upside down.


Automotive tire Gas Wood Automotive wheel system Auto part

For tonight I'm done. I'll grind and clean up and fill in more if I need to. Welding stainless steel with an oxy-acetylene torch is easy, just like mild steel. I found a spool of stainless steel safety wire at Harbor Freight. I use borax as flux. It acts like it wants to be welded.

I've seen holes like that. I started buying patches at the brick and mortar auto parts stores. I ended up playing wack a mole with holes popping up every time I patched one, or soon after. A friend's brother, aka Honda tech, said that's usually what happens and advised to start replacing parts. I never bought patch material again....

BTW- I was able to get a day use permit here in California when the DMV saw my iQ was still insured. Maybe get insurance and then try....

It was actually cheaper to keep it insured along with two other more valuable cars so my wife kept it insured even with the PNO (planned non-operation).

I see that I can get a new oem manifold/converter for $322 shipped. More areas on the converter look iffy as I work on it. The manifold converter is way cheaper than the second converter.

I have to go to NY DMY to pay the sales tax on it. There is a MV-51b that might work for me. 30 days for $12.50.....

Interestingly the way it works here is I get a single day use within 60 days of application, absolutely free. They hand you the paper/permit and you are supposed to fill out the specific date you are going to use it. I folded it up so that part wasn't visible, then taped it to the lower right of the windshield where a temporary registration was usually put when you buy a car. (Nowadays they give a temporary paper license plate when you buy a new car or car without plates. While I didn't abuse it and only used it one day, I did not put a specific date lest I needed to use it a different day. I was able to get it to pass a smog check that one day, BUT after driving it around some because I had just reconnected the battery...

Yeah unfortunately when they rust through there are usually hidden weak spots that just didn't quite get there just yet, and patching one part increases pressure on all those weak spots one by one, blowing out the next weakest one, on, and on...

They denied me for any sort of pass without having a registration or title. I can still get a pass to drive to the state anti-theft inspection if I get the car inspected and send that with my salvage title application.

My new manifold/converter/pipe is coming by the weekend. I did patch up the old one with a lot of welding and it's so much quieter. Also, on my OBD2 device, I can see both O2 sensors working! I'm also not getting the the rich or lean (I forget which) code anymore. Transmission whines at first just in park, but it's always getting better. I can do some drive cycles now.

That is the second donut gasket. The first one, between the two converters is about $33. I ordered and will pick up in the morning, the part number you gave. The pipe is the same diameter, so it should at least work temporarily but probably longer. The FelPro version at the local store is just $16. If it just doesn't work, I'll use it where it is meant to be, ahead of the muffler.

You might need the gasket, part number 17451-f2010. About $18 plus shipping. ;)

I didn't pay attention when I first bought the second O2 sensor. All the Bosch sensor would do is swing from low to high voltage and back over maybe 15 seconds. No response to the throttle. I installed a Denso today and it works great. The voltage is in the correct range and responds with the throttle. Also today the exhaust is quieter and the transmission didn't make any noise.

The battery light is on half the time, maybe a little more than half the time. I don't have any actual trouble other than the light. The battery is at a healthy voltage in the morning. It charges at over 14 volts, but I will double check that. The voltage at the ECU is 13.52 V according to my OBD2 scanner. The battery and alternator are new.

Battery light problem was the dark green wire on the "E" connector in the fuse box. It looked good until I went to take out the pins one by one to clean and freshen them up. It was missing the little contact tongue. I soldered in a contact from a good part of my old harness. It's a wire from one of the 4 pins on the alternator to the dash light for the battery.

I've only ever tried one Bosch item. It can happen.

I'm trying out TechStream now. I should have kept on looking until I found the last version of the cable. I bought a 1.4.8 version, but it was actually a 1.4.1 version. I'm returning it. I will but either the 2.0.4 or go different and get a VXDiag VCX NANO.

I keep on calling the NYS antitheft number. It has been saying they are working on applications arriving September 14 for weeks now. I'm thinking they don't update it regularly. Maybe I will have the appointment next year at this rate.
