Hey guys I have a 2004 manual and the SES is on with code P0031 Most likely the o2 sensor bank 1 sensor 1 just want to know if someone else have had this code before and if is really the o2 , a blow fuse or something else? Thanks

I have a 2003 with 80K. I just got the SES light, and the code is P0031. I assume I need an O2 sensor, but I plan inspecting the wiring and connectors leading to the sensor. I had the SES light this summer and this was fixed replacing a camshaft position sensor. I'm suspicious now of a wiring issue. --Spike

 

Please let me know if you resolve the problem I will update once I fix mine

 

UPDATE: replaced o2 fuse and replace bank 1 sensor 1 and the problem was fixed and today I passed emmision.
