Hey!
Laptop read error codes and ended up with
"MIL: on"
"DTC:1"
"DTC: p0141- bank1sensor2 mulfunction"

MIL lamp works as usual : engine off - MIL is on, engine on - MIL is off.

What does it mean?

And also i wanted to clear those error codes but stopped because warning message said it will do a lot of things to ECU, clearing lots of things that "may cause car to act poorly till it reconfigures itself"

What actually happens there ? And if i haven't fixed the problem, that it indicates, what will be after "clearing"? Will it appear back?

Thank you!

 

Its considered a soft code,it failed and some point in time causing the ecu to store the code in memory,it needs to fail five consecutive times before the mil is illuminated. The ecu will clear the dtc from its memory after fifty cycles of the ignition key as long as the sensor does not fail again. Just go ahead and clear it you should be fine,but it looks like you probably gonna need to replace the sensor soon.

 

Exactly what i wanted to hear!Thank you!
