2013 Mazda CX-5 - Code PO13A

My check engine light came on yesterday I had it checked this morning and this was the code. PO13A now the light has gone out. Do I still need service?

I think I would drive it if the CEL stays off. But if it comes on again would take it in, Diagnostic May be up to $150 but better than throwing parts at it. Driving with theCEL on can result in damage to other engine components.

P013A Possible Causes

  • Faulty Heated Oxygen Bank 1 Sensor 2
  • Heated Oxygen Bank 1 Sensor 2 harness is open or shorted
  • Heated Oxygen Bank 1 Sensor 2 circuit poor electrical connection
  • Inappropriate fuel pressure
  • Faulty fuel injectors
  • Intake air leaks may be faulty
  • Exhaust gas leaks
