goahead Report post Posted August 16, 2017 I'm hoping someone can help me understand the possible problems with my issue. my 2004 lambo G is throwing O2 fault codes. At first I thought it was odd because All 4 of the O2 sensors were just replaced 3 months ago, but regardless I just replaced the 2 sensors throwing the codes. However, after clearing the codes multiple times and driving the car(in hopes of clearing the codes) I still cannot get the O2 sensors to stop throwing the error codes. Dashboard shows the "1-5" error warning. ECU error codes: P0131 - O2 Sensor Circuit Low Voltage Bank 1 Sensor 1 P0140 - O2 Sensor Circuit No Activity Detected Bank 1 Sensor 2 P0141 - O2 Sensor Heater Curcuit Bank 1 Sensor 2 As mentioned, because of these errors I had both sensors on Bank 1 replaced again but the codes come back quickly after clearing them. I was also thinking it could be a tripped Relay so I looked in the fuse box behind the passenger seat and checked most of the relays and they looked fine. I am wondering if there is relays somewhere else for the O2 sensors that just need to be replaced? Otherwise I have no idea what the issue could be and I appreciate any help!

STEEVE1234 Report post Posted February 9, 2018 It looks like that it's not the O2 sensors. You should have a mechanic check it out. Quote Share this post Link to post Share on other sites More sharing options...
