P247E — Exhaust Gas Temperature Out of Range Bank 2 Sensor 3

P247E — Exhaust Gas Temperature Out of Range Bank 2 Sensor 3. A fault in the sensor and actuator circuits. The car is usually drivable while you plan the repair. Typical causes: control module driver fault, corroded, loose or damaged connector, 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

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P247E is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. 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.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the exhaust gas temperature out of range bank 2 sensor 3 for damage, corrosion, chafing or poor contact.
  4. Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
  5. Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P247E does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P247E (parts and labor, USD, independent shop rates): Control module repair: $300–$1,000; Replace the faulty sensor or actuator: $150–$500; Repair wiring or connectors: $80–$250. Overall, fixing P247E 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 P247E?

The most common causes are: control module driver fault, corroded, loose or damaged connector, blown fuse feeding the circuit.

How much does it cost to fix P247E?

Control module repair — $300–$1,000; Replace the faulty sensor or actuator — $150–$500; Repair wiring or connectors — $80–$250. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

Will P247E clear itself?

Sometimes P247E 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.

What are the symptoms of P247E?

Drivers most often notice: 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.

What does OBD2 code P247E mean?

P247E — Exhaust Gas Temperature Out of Range Bank 2 Sensor 3. A fault in the sensor and actuator circuits. The car is usually drivable while you plan the repair. Typical causes: control module driver fault, corroded, loose or damaged connector, blown fuse feeding the circuit.

What does P247E mean?

Behind P247E is a specific failure in the sensor and actuator circuits: exhaust gas temperature out of range bank 2 sensor 3. The onboard computer stores it in the powertrain (engine/transmission) group after verifying the fault over repeated checks.

In this definition, “Bank 2” is the side of the engine opposite to cylinder 1 and “Sensor 3” 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.

To set P247E, the control module compares live readings of the sensor and actuator circuits against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.

What causes P247E?

  • control module driver fault
  • faulty sensor or actuator of the affected circuit
  • blown fuse feeding the circuit
  • poor ground connection
  • open or shorted wiring in the circuit
  • corroded, loose or damaged connector

Common symptoms of P247E

Can you drive with P247E?

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.
