P220ENOx Sensor Heater Control Circuit Range/Performance (Bank 1 Sensor 1)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P220E says the heater of the upstream NOx sensor on bank 1 is not behaving as commanded. Ford's 6.7L and 3.0L diesels bundle several checks under it: an open heater found by the sensor hardware, a short to positive (over 5 V on the heater), a short to ground (0 V), and a duty cycle that differs from the expected one by more than 20 percent. Ford TSBs 24-2136 and 24-2148 cover 2020-2023 F-Super Duty and F-650/F-750 trucks with P220E alongside P2201 and P2209, fixed with a new sensor plus PCM and TCM software. Volvo and Mack state that P220E with failure type 93 usually calls for a new inlet sensor. P2205-P2207 are the plain heater circuit faults, P220F the downstream sensor.
- What you may notice
- Malfunction indicator lamp on
- Upstream NOx sensor slow to become ready after start
- Often stored with P2201 or P2209
- Likely causes
- LikelyAged heater element in the upstream NOx probe
- PossibleSensor and PCM software (Ford 6.7L 2020-2023, TSB 24-2136/24-2148)
- PossibleHeater wiring or ground with high resistance or shorts
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
