P0113 Code — Intake Air Temperature Circuit High Input Bank 1
P0113: Intake Air Temperature Circuit High Input Bank 1. This is a Powertrain trouble code — a generic OBD-II code that means the same thing on every make and model. Severity is generally Medium.
Cooling-related faults can lead to overheating. Monitor the temperature gauge and address soon.
What the P0113 code means
| Code | P0113 |
|---|---|
| Definition | Intake Air Temperature Circuit High Input Bank 1 |
| System | Powertrain — engine, transmission and associated drivetrain systems |
| Code type | Generic (SAE J2012 standard) |
| Subsystem | Fuel and air metering |
| Fault reference | Fault #13 within the Powertrain group |
| Typical severity | Medium |
The letter P tells you the code belongs to the Powertrain family, covering engine, transmission and associated drivetrain systems. The second digit shows this is a standardized SAE code, so the definition above applies to any OBD-II compliant vehicle from 1996 onward. Within powertrain codes, it points to the fuel and air metering area.
Common causes of P0113
Because P0113 relates to the Powertrain system, likely culprits fall into these buckets. Confirm the actual fault with a scan before replacing parts:
- Faulty or aging sensors and their wiring in the affected circuit.
- Loose, corroded or damaged connectors and grounds.
- A failing component the code names directly (valve, solenoid, module or actuator).
- Related upstream issues — vacuum leaks, low fluids or a weak battery can trigger secondary codes.
How to fix a P0113 code
- Read and record the code with an OBD-II scanner, along with any freeze-frame data.
- Inspect the wiring, connectors and components in the Powertrain circuit the code points to.
- Repair or replace the confirmed faulty part — avoid swapping parts on a guess.
- Clear the code and drive a full cycle, then re-scan to confirm it does not return.
Recall repairs are free at a dealer, so it is worth checking for an open recall or decoding your VIN before paying for diagnostics — some faults are covered.
