Intake air temperature circuit high input
P0113 means the controller saw intake-air-temperature circuit voltage corresponding to an implausibly cold value or an open/high-input condition. It does not identify a failed part or establish a repair price by itself.
Conditions that can produce P0113
These are diagnostic branches, not a ranked shopping list. Testing order depends on the exact vehicle and failure scene.
- Disconnected sensor or spread terminal
- Open signal or sensor-ground circuit
- Failed temperature element
- Connector contamination or harness damage
- Incorrect component or pinout
What to inspect next
- Compare intake temperature with ambient and coolant after a cold soak
- Inspect connector fit and shared sensor ground
- Use exact circuit voltage and resistance specifications
- Confirm whether the temperature element is part of another sensor assembly
What strengthens the answer
Prove what changed
Preserve the pre-repair record, document exactly what changed, and repeat the relevant operating condition safely. Confirm that current or pending faults do not return, review permanent-code and readiness state where applicable, and state which tests or modules remained unavailable.
P0113 questions
What does P0113 mean?
The controller saw intake-air-temperature circuit voltage corresponding to an implausibly cold value or an open/high-input condition.
Does P0113 identify the broken part?
No. On many negative-temperature-coefficient sensor circuits, an open circuit appears extremely cold. Exact pinout, bias voltage, and sensor integration vary; the sensor may be combined with the airflow or pressure sensor. Confirm the exact vehicle definition and test the relevant branches before ordering a part.
Is it safe to drive with P0113?
Driving risk depends on the symptoms, warning-lamp behavior, and affected system. Stop for unsafe operation, a flashing warning lamp, smoke, fuel odor, overheating, braking or steering changes, or electrical heat.
How much does P0113 cost to repair?
The code alone cannot produce a defensible repair price. Cost depends on the confirmed cause, exact vehicle, parts choice, labor time, local labor rate, tax, supplies, and whether related damage is present.
What should I record before clearing P0113?
Record the reporting module, stored or pending status, freeze-frame data, readiness state, related codes, symptoms, battery voltage, and unavailable evidence. Clearing first can erase the most useful failure-scene context.
This page explains a commonly standardized code at a general level. Confirm the exact definition, module, status, test conditions, thresholds, wiring, and service process for the vehicle using current official information.
