P2476 — Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 4
OBD2 code P2476 flags a problem with the sensor and actuator circuits (exhaust gas temperature sensor circuit high bank 2 sensor 4). The car is usually drivable while you plan the repair. Common culprits: faulty sensor or actuator of the affected circuit, control module driver fault, blown fuse feeding the circuit.
powertrain (engine/transmission)
Is it safe to drive?
Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.
How to diagnose with an OBD scanner
- Read the code and freeze frame Connect an OBD2 scanner, confirm P2476 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
- Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
- Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the exhaust gas temperature sensor circuit high bank 2 sensor 4 for damage, corrosion, chafing or poor contact.
- Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
- Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
- Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2476 does not return.
Approximate repair cost
Repair cost depends on which component actually failed. Typical scenarios for P2476 (parts and labor, USD, independent shop rates): Repair wiring or connectors: $80–$250; Control module repair: $300–$1,000; Replace the faulty sensor or actuator: $150–$500. Overall, fixing P2476 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.
Common questions
What is the most common cause of P2476?
The most common causes are: faulty sensor or actuator of the affected circuit, control module driver fault, blown fuse feeding the circuit.
How much does it cost to fix P2476?
Repair wiring or connectors — $80–$250; Control module repair — $300–$1,000; Replace the faulty sensor or actuator — $150–$500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.
Will P2476 clear itself?
Sometimes P2476 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.
How do I diagnose P2476 myself?
Start with a scan: confirm P2476, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the sensor and actuator circuits, and verify the suspect component against live data before buying parts.
Is it safe to drive with P2476?
In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.
What does P2476 mean?
The engine control module sets P2476 when it detects a fault in the sensor and actuator circuits. In practical terms: exhaust gas temperature sensor circuit high bank 2 sensor 4. The code belongs to the powertrain (engine/transmission) group of OBD2 codes.
In this definition, “Bank 2” is the side of the engine opposite to cylinder 1 and “Sensor 4” is the downstream (after the catalytic converter) sensor. Mixing up banks and sensor positions is the most common DIY mistake with this code — verify the physical location before replacing anything.
The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2476 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.
What causes P2476?
- corroded, loose or damaged connector
- faulty sensor or actuator of the affected circuit
- blown fuse feeding the circuit
- control module driver fault
- open or shorted wiring in the circuit
- poor ground connection
Common symptoms of P2476
- the affected system operates intermittently or not at all
- possible limp mode depending on the affected component
- Check Engine Light on
- increased fuel consumption in some cases
