What P2476 means
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.
P2476 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2476
- MIL on
- Probe reads maximum or an implausibly hot value
- Regeneration blocked
Common causes of P2476
- Most likelyOpen signal or ground wire, often heat-damaged
- PossibleConnector loose or not locked after service work
- Less likelySignal wire shorted to a supply voltage
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2476 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| 76 | The exact fault in that area. |
What to do next
- Note P2476 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2476
What does P2476 mean?
P2476 means "Exhaust Gas Temperature Sensor Circuit High (Bank 2 Sensor 4)". P2476 covers the opposite end of the scale from P2475: the signal of bank 2 probe 4 sits above its usable ceiling. It is a generic code, so it means the same on every make.
Is it safe to drive with P2476?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2476 fail an emissions test?
Yes, it can. P2476 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2476 to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2476 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
