Positive about the number. Took a photo of the scan.
It reads, “Heated Oxygen Señor HeaterControl Circuit Low Bank 1 Sensor 3 - open circuit"
What is an O2 sensor failure? Do I need to take care of
it soon rather than just before inspection?
Have called two shops. Both refused to name a price.
One gave a range $200- 900, dependent on what his mechanic
would tell him is needed. This happened a few days after an
oil change. Am wondering whether that shop triggered the Check
Engine….
Thank you!
