P013C Ford Code - Oxygen Sensor Slow Response Rich to Lean Bank 2 Sensor 2

Quick Answer

During a Deceleration Fuel Shut-Off (DFSO) event, the Powertrain Control Module (PCM) monitors the rear heated oxygen sensor (HO2S) signal to determine if the signal is stuck in range. Common causes include Faulty Heated Oxygen Bank 2 Sensor 2, Heated Oxygen Bank 2 Sensor 2 harness is open or shorted, Heated Oxygen Bank 2 Sensor 2 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

What it means: P013C Ford indicates Oxygen Sensor Slow Response Rich to Lean Bank 2 Sensor 2.
Common causes: Common causes include Faulty Heated Oxygen Bank 2 Sensor 2, Heated Oxygen Bank 2 Sensor 2 harness is open or shorted, Heated Oxygen Bank 2 Sensor 2 circuit poor electrical connection.
Severity: Moderate - service should be scheduled soon.
Can I drive?: The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P013C Ford Description

During a Deceleration Fuel Shut-Off (DFSO) event, the Powertrain Control Module (PCM) monitors the rear heated oxygen sensor (HO2S) signal to determine if the signal is stuck in range. The PCM expects the signal to exceed a calibrated rich or lean value within a calibrated amount of time. If the signal voltage remains less than the rich value after a number of occurrences, the PCM intrusively controls the fuel system rich over increasing time periods in an attempt to force the signal to greater than the calibrated rich value. The test fails when, after three consecutive intrusive attempts, the signal cannot be forced greater than the calibrated rich value. Also, if the signal voltage remains greater than the lean value after a calibrated amount of time with the fuel injectors off, a counter is incremented. The test fails when after three consecutive occurrences the signal is not less than the calibrated lean value.
