P2476Exhaust Gas Temperature Sensor Circuit High (Bank 2 Sensor 4)

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
P2476 covers the opposite end of the scale from P2475: the signal of bank 2 probe 4 sits above its usable ceiling. Because the probe forms a voltage divider with a pull-up resistor in the control unit, an interrupted wire, a disconnected plug or a short to a supply voltage all drive the input high. For the bank 1 equivalent P2471 Ford uses more than 4.90 V in its 2015 diesel summary and more than 2.66 V in the 2023 edition, both as continuous checks. P2476 is not listed by any maker in public documents; only engines with two banks and four probes per bank could set it. Expect a lit MIL and a substitute temperature, which can stop regeneration.
What you may notice
  • MIL on
  • Probe reads maximum or an implausibly hot value
  • Regeneration blocked
Likely causes
  • LikelyOpen signal or ground wire, often heat-damaged
  • PossibleConnector loose or not locked after service work
  • RareSignal wire shorted to a supply voltage
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
