P2514 — Event Data Recorder Request Circuit High

P2514 — Event Data Recorder Request Circuit High. A fault in the sensor and actuator circuits. The car is usually drivable while you plan the repair. Typical causes: poor ground connection, blown fuse feeding the circuit, corroded, loose or damaged connector.

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 P2514 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 event data recorder request for damage, corrosion, chafing or poor contact.
  4. Subsystem check With the event data recorder request disconnected, measure signal voltage at the harness connector: a high reading with the component unplugged indicates a short to power in the harness; if it drops to normal, the component itself is faulty.
  5. Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
  6. Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
  7. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2514 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2514 (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 P2514 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

How do I diagnose P2514 myself?

Start with a scan: confirm P2514, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the event data recorder request, and verify the suspect component against live data before buying parts.

How much does it cost to fix P2514?

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 P2514 clear itself?

Sometimes P2514 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 does OBD2 code P2514 mean?

P2514 — Event Data Recorder Request Circuit High. A fault in the sensor and actuator circuits. The car is usually drivable while you plan the repair. Typical causes: poor ground connection, blown fuse feeding the circuit, corroded, loose or damaged connector.

What is the most common cause of P2514?

The most common causes are: poor ground connection, blown fuse feeding the circuit, corroded, loose or damaged connector.

What does P2514 mean?

Behind P2514 is a specific failure in the sensor and actuator circuits: event data recorder request circuit high. The onboard computer stores it in the powertrain (engine/transmission) group after verifying the fault over repeated checks.

“Circuit high” means the control module sees a voltage on the event data recorder request circuit that is above the expected range — typically close to battery voltage. Physically this points to a short to a power feed, a broken ground return, or a failed component pulling the signal line high.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P2514 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

Common symptoms of P2514

  • Check Engine Light on
  • increased fuel consumption in some cases
  • the affected system operates intermittently or not at all
  • possible limp mode depending on the affected component

What causes P2514?

  • failed event data recorder request pulling the signal high
  • signal wire shorted to battery positive
  • open ground return of the event data recorder request
  • control module driver fault
  • corroded, loose or damaged connector
  • blown fuse feeding the circuit
  • faulty sensor or actuator of the affected circuit
  • open or shorted wiring in the circuit

How to diagnose P2514

  1. Connect an OBD2 scanner, confirm P2514 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. 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. Visually inspect the wiring harness and connectors related to the event data recorder request for damage, corrosion, chafing or poor contact.
  4. With the event data recorder request disconnected, measure signal voltage at the harness connector: a high reading with the component unplugged indicates a short to power in the harness; if it drops to normal, the component itself is faulty.
  5. Measure reference voltage, ground and signal continuity at the component connector.
  6. Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
  7. Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2514 does not return.
