OXYGEN SENSOR

2001 Pontiac Grand Am • 6 cylinder 2WD Automatic • 69,785 miles

Where is the front oxygen sensor located in the 2001 Pontiac Grand Am GT1. V-6 3.4L? I have the part and want to change it due to a SES light but just need to find it. Thanks.

The code was 02 htr ckt. B1 s1. So I have the sensor before the converter.

If you could give me the actual code number that would really help me find the info it's a P followed by a four digit number.

I'm sorry I thought your engine had two upstream o2 sensor's it only has one.I posted a diagram of where it is sorry about that.I recommend using a o2 sensor socket to change it but you don't that's up to you.
