This code usually needs a check soon to find out what is wrong.

P0113 meaning
Intake Air Temperature Sensor 1 Circuit High Bank 1
The same first verdict Car Assist shows from this code alone, before a diagnosis. The code does not tell the app whether the warning light is flashing.
What this code doesn’t tell you
A code says where the car noticed a problem. It does not prove which part failed, whether the fault is still present, or what repair this car needs. The engine, other codes, freeze frame and live readings matter.
Usual causes, most likely first
The order is a starting point across cars; the exact engine and its readings can change it.
- Unplugged intake temperature sensor
- Broken wire or poor connector contact
- Failed temperature sensor
What you can check
With the engine off and cold, look for an unplugged connector near the air filter, particularly after recent work. A high circuit code can mean an open wire rather than hot air.
Words the car uses
- Stored codes
- Faults the car has confirmed and saved. They help explain a check-engine light, but a code alone does not prove which part needs replacing.
- Freeze frame
- A snapshot of the engine's readings when a fault was recorded. It helps show the conditions that caused the fault, even if the car now seems fine.
- Readiness monitors
- The car's own checks of its emissions systems. An unfinished check means the car has not tested that system yet, so a clean code scan may miss a fault.
- Intake air
- The air entering the engine; outside air is the surrounding air. Their temperatures help the computer choose the fuel amount and can help explain poor running.
- Air flow (MAF)
- The amount of air flowing into the engine. The computer uses it to choose how much fuel to add, so a wrong reading can make the engine run poorly.
Find out what’s causing yours
Car Assist reads your car through an OBD-II adapter and your iPhone. Its assistant uses the codes, freeze frame and live readings to work through the likely cause with you.
