Hi guys,
I’m having a code P0051. I did change the O2 sensors but no use. Any help is highly appropriated

Thanks hugs.

 

EXACTLY which sensor did you replace, there's 4 of them. That code is for the bank2 sensor1, that's the upstream one mounted in the header on the left side of the car (driver side for a left-hand-drive model).

 

Hi Cleric,
Yes I did change the sensor bank2 sensor1 and the problem is the same. I will check if the new sensor is Ok or busted.....
wish me luck.....

thanks for your replay.

 

did you ever figure out what was happening? I’m having the same problem. The only code I’m getting is P0051. I replaced the bank two sensor one A/F sensor with a new denso sensor (it has the wideband six pin air fuel sensor not the 4 pin)on my 2003 g35 I checked the fuse and it was good starting to think it’s a problem in the hardness
