Replaced O2 Sensor and still get Check Engine Light On.
Hi Guys,
2 different shops did reads on my check engine light codes, I even paid $100 for one of them to do a full test of all sensors to identify which one was bad.
Their diagnose was code P0141, oxygen sensor heater, o2 sensor had to be replaced. They said was the front one.
I bought an original Honda o2 front sensor, and I replaced it myself yesterday.
Very simple, unscrew the sensor, unplug the electrical conection, screw new sensor in and plug connection.
So I thought.
I unplugged the battery to reset the CEL light and it worked.
But once I drove off this morning, the light was back on. WTF?
I checked and the new sensor is well screwed and connected.
Could the shops have given me a bad diagnosis? Maybe the problem is the other sensor? Maybe it's the electrical part that connects to the o2 sensor?
They said was the front one. But now as I this thing didn't work and I am doing more research I think they told me the wrong one. I think I should have replaced the rear one.
See some pictures attached I took this morning. Did I replace the right one? The one before the catalytic converter, that's gotta to be the front sensor. The rear o2 sensor would be the one connected to the second 1/3 of the catalytic converter.
Opinions? Suggestions?
I really appreciate.
Thanks
