P0113 on a 2012 Chevrolet Traverse
Intake Air Temperature High Input
P0113 on a 2012 Chevrolet Traverse indicates intake air temperature high input. It usually stays drivable short-term but should be diagnosed promptly. The most common cause is disconnected or unlatched iat / maf-iat connector (typically $0–$50). Confirm the root cause before replacing parts.
What does P0113 mean on a 2012 Chevrolet Traverse?
P0113 is set when the ECM sees the intake air temperature sensor signal voltage above the calibrated maximum — typically a reading that would represent an unrealistically cold air temperature (often below −40 °F / −40 °C). This is the textbook fingerprint of an open circuit at the IAT sensor: a disconnected sensor, a broken signal wire, or a failed sensor element.
This guide covers P0113 across the 2010-2014 Chevrolet Traverse generation — the symptoms, causes, and diagnostic steps below apply to every model year from 2010 through 2014.
Is it safe to drive a 2012 Chevrolet Traverse with P0113?
In most cases a 2012 Chevrolet Traverse stays drivable for short trips with P0113 active, but diagnose and repair it promptly. This is a low-severity code — ignoring it can lead to further damage or a failed emissions test.
What are the symptoms of P0113 on a 2012 Chevrolet Traverse?
- Check Engine Light is illuminated
- Slightly harder cold starting in some cases
- Mild reduction in fuel economy
- Reduced power under hard acceleration (engine adds extra fuel for "cold" air)
- Often no noticeable drivability problem at all
What causes P0113 on a 2012 Chevrolet Traverse?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Disconnected or unlatched IAT / MAF-IAT connector | Most common | $0–$50 |
| Open circuit in the IAT signal wire (broken, chafed, or pinched) | Common | $80–$350 |
| Failed IAT sensor element (open internally) | Common | $30–$150 |
| Corroded sensor connector pins | Common | $30–$200 |
| Damaged sensor body from intake backfire | Occasional | $30–$200 |
| Failed PCM input (extremely rare) | Rare | $400–$1,500 |
How to diagnose this on a 2012 Chevrolet Traverse
-
Confirm where the IAT sensor lives on this engine
Modern engines fall into two configurations: a standalone IAT sensor in the air intake tract, or a combined MAF/IAT assembly where the IAT element is built into the mass airflow housing. Both share P0113 — the diagnostic difference is where to find the connector and which wires carry the IAT signal.
Tools: Vehicle-specific service information
-
Read IAT temperature on the scan tool
A working IAT reads close to ambient air temperature when the engine has been off long enough to cool. Compare to the coolant temperature reading at cold start — they should agree within a few degrees. An IAT reading of "−40 °F" or "−40 °C" is the classic open-circuit fingerprint.
Tools: Scan tool with IAT PID
-
Inspect the connector and wiring
Unplug the IAT connector and inspect for corrosion, water, or bent pins. With the connector unplugged and the key on, the scan tool should still report a fixed "very cold" value — that confirms an open circuit signature is what set the code.
Tools: Electrical contact cleaner, Flashlight
-
Bench-test the IAT sensor with a multimeter
With the sensor removed, measure resistance across its terminals at room temperature. Compare to the service manual — most NTC IAT sensors read 2.0–4.5 kΩ at 68 °F (20 °C). Infinite resistance means the sensor is open and dead. Heating the sensor gently should cause resistance to drop.
Tools: Multimeter, Heat gun or hair dryer (optional), Service spec sheet
-
Jumper test the signal wire
With the IAT disconnected, briefly jumper the signal wire to ground and observe the scan tool reading — it should swing from "very cold" to "very hot" (P0112 territory). If the reading does not change, the wiring or PCM input is at fault rather than the sensor.
Tools: Jumper wire, Scan tool

About the 2010-2014 Chevrolet Traverse
The 2010-2014 Chevrolet Traverse was commonly sold with the following powertrains: 3.6L V6, 2.0L Turbo I4. Common trims include L, LS, LT, RS, Premier, High Country.
P0113 vs P0112
These are the two ends of the same circuit:
- P0112 — IAT signal reads too low (sensor sees a very high temperature, often “300 °F”). Usually a shorted-to-ground signal wire or a sensor failed in the closed direction.
- P0113 — IAT signal reads too high (sensor sees a very low temperature, often “−40 °F”). Usually an open circuit — disconnected, broken wire, or sensor open internally.
Why P0113 rarely affects drivability
Modern ECMs use the IAT for relatively minor fuel-trim corrections and to fine-tune cold-start enrichment. With a missing IAT signal, the ECM uses a default value (usually around 70 °F) and the engine runs essentially normally. This is why many drivers report P0113 with no symptoms at all beyond the Check Engine Light.
Combined MAF/IAT assemblies
On most modern vehicles the IAT is integrated into the MAF housing as a single assembly. When the IAT element fails, the entire MAF assembly must be replaced — there is no separate IAT to service. Confirm the part number before ordering; combined assemblies are 4–10× the cost of a standalone IAT.
