Hello all.....I was driving yesterday and the light came on. How can I diagnose it myself?
Ps, do I need a code reader?
Thx in advance,
Manny

May I ask where the location is on the Element, for the diagnostic code reader to be plugged into?
Thanks for the pics!

My-oh-my your Element is so clean underneath. I have a bit of snow the ground up here right about now..



I did the code reading thing and got two results:

- PO135

- PO420

PO135 is: 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

PO420 is: Catalyst System Efficiency Below Threshold (Bank 1)
