How many oxygen sensors do I need to order? upstream and downstream

5

Asked by May 13, 2015 at 12:01 AM about the 2006 Buick Rainier CXL AWD

Question type: Maintenance & Repair

My check engine light keeps coming on and then will go off.  Then after a month it will come back on.  The first time it came on I took it to an O'reilly's and they ran a diagnostic and told me that is was a bad o2 sensor.  The car has 105,000 miles on it. I am wanting to order the parts online but need to know exactly what to order.

have your mechanic check and he should be able to tell you to be sure

You still need the proper codes, just saying an O2 sensor doesn't get you anywhere. These codes only aid in diagnosis, it could be just the sensors or the wiring maybe at fault or the catalyst not functioning properly. So have it rechecked by someone that knows what they are doing.
