03 oddy is continuously stalling after converter was stolen

Porky20023 · Mar 30, 2022

Hi all! So I feel that we have hit a dead end with trying to figure out why my 03 odyssey is stalling. Last year, the converter was stolen. In the process of stealing the converter, the upstream o2 sensor wires were damaged. I was able to eventually have an aftermarket converter installed, but the wires were never fixed. Ever since the original converter was taken, I have had problems with the van stalling. It seems like right before it stalls, the traction control light comes light comes on. Also, the stalling usually occurs when slowing down to come to a stop or yield. The van has been to two different mechanics and no one can find the issue. One shop replaced the crankshaft position sensor, but of course that did not stop the stalling. Occasionally the transmission will slip as well, which triggers the tcs light and a stall. Idk if this is connected in any way, but thought I would include that part. Any input would be greatly appreciated!!

So, you are aware of damage to the upstream O2S wiring, have ignored that while having two different shops search and swap at least one other sensor. But nobody thinks to repair the circuit for the primary fuel control.

I have nothing to say...meaning I'm speechless.

Both shops were told about the damage, and they both said the sensor will not cause stalling issues. Maybe they simply don't want to mess with the wiring. I was incorrect about the crankshaft sensor as well. It was not replaced. The shop only mentioned that could be the problem. A code was thrown at one point, but after the code was cleared, they could not get another reading. I do not recall any mention of primary fuel control.

Your PCM uses input from the front O2Ss to continually adjust the fuel injector pulse width, controlling the amount of fuel delivered to the cylinders.

So basically, I need to find someone willing to fix the wiring? I was a little shocked when I was told the o2 sensor wouldn't cause the van to stall.

I ain't diagnosing from afar. Perhaps one or both have looked at the datastream, examined the wiring, and judged no damage because the data looks good. It just stood out in your description. If it were the rear, it would be a different story.
