What P0113 means
Intake air temperature sensor 1 is the first air temperature sensor in the intake path; depending on the vehicle it is built into the mass air flow sensor, mounted near the air filter or, on some naturally aspirated GM engines, fitted in the intake manifold. Most versions are NTC thermistors in a 5 V divider: the hotter the air, the lower the signal voltage. P0113 means the signal is above its valid range. With an NTC sensor that is typically an open circuit – connector off, broken wire, open sensor or missing ground – or a short to a voltage source, and the module would read an extremely cold value (GM about −60 °C). Documented limits: Ford gasoline above 4.96 V for 5 s, Ford diesel above 4.91 V, GM above about 127 kilohms. A classic cause is a sensor left unplugged after an air filter change; one manufacturer bulletin describes broken wires at the connector caused by harness tension. Monitoring is continuous, GM needs two trips.
P0113 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.2 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0113
- Check engine light on
- Usually hardly noticeable
- Slightly richer mixture and higher consumption possible
- Torque limitation on some systems
Common causes of P0113
- Most likelyConnector unplugged or loose, or wire broken
- Most likelySensor open internally
- PossibleSensor return (ground) wire open
- Less likelySignal wire shorted to a voltage source
- Less likelyEngine control module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0113 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 1 | Area: fuel and air metering. |
| 13 | The exact fault in that area. |
What to do next
- Note P0113 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0113
What does P0113 mean?
P0113 means "Intake Air Temperature Sensor 1 Circuit High Bank 1". Intake air temperature sensor 1 is the first air temperature sensor in the intake path; depending on the vehicle it is built into the mass air flow sensor, mounted near the air filter or, on some naturally aspirated GM engines, fitted in the intake manifold. It is a generic code, so it means the same on every make.
Is it safe to drive with P0113?
Drive gently and only to a workshop. With P0113 the car can go into limp mode (reduced power) to protect itself.
Will P0113 fail an emissions test?
Yes, it can. P0113 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0113 to fix?
Difficulty: easy. A typical repair takes 0.2 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0113 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
