How many oxygen sensors do I need to order? upstream and downstream
5

Asked by Dedra 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.

The correct answer is: 4...... You car takes 2 for upstream and 2 for downstream... You will need to have a mechanic run a diagnostic to determine which one for sure...
