I have replaced the Bank 1 Sensor 1 2 times and still get the CEL pop back up after clearing it. Must be something else causing the sensor malfunction but I do not know where else to pin point this. Anyone have any suggestions? I would greatly appreciate it.

Did you use a Denso sensor?

Ravencrave

Yes and brand new.

If you have access to an OBD 2 code scanner capable or monitoring live data, monitor the A/F sensors and see what you get.

Also are you sure your are replacing it with the right OE Denso part no? Where did you buy It?

Does the code come back immediately after you start the car?

Could also be a wiring harness/connector issue, or (less likely) an ECU issue.

If all else fails, and beore proceeding further, disconnect the battery for a few minutes, than reconnect.

Yes I have used an OBD II scanner to get the codes and erase them but dont know about it monitoring the sensors. It is the right part number and came from Ebay. I inspected the package and all is sealed and in the correct box label. I have been riding with this issue for almost 2 years and just now getting around to try and pinpoint it. It doesnt effect the performance, just the annoying check engine light. Black tape works but still want it fixed. I was also thinking along the lines of the wire harness.

An OBD II code reader just reads the codes, and let's you reset the check engine light. An OBD II scanner will do the same, but will also display live data, showing you what the sensors are doing in real time. This is what you need.

Also, eBay is rampant with fake parts, so its best to buy from an established eBay seller with good feedback, and reputation. Otherwise, you never know if you got the real part.

You really need to deal with this ASAP, otherwise you may end up with a malfunctioning, or blocked catalytic converter. Than it really gets expensive.

Thanks for the feedback guys! I'll see if my neighbor has a meter when he gets home along with seeing if his OBD II is a scanner or just a reader. The video posted will help a great deal as well and thanks!
