P0113 on Mazda vehicles
Intake Air Temperature High Input — what it means on a Mazda, whether it's safe to drive, and the fixes by model and year.
P0113 on a Mazda means intake air temperature high input. Most vehicles stay drivable short-term, but diagnose it promptly. The most common cause is disconnected or unlatched iat / maf-iat connector (typically $0–$50). Pick your Mazda model below for its known failure patterns, recalls, and TSBs.
What does P0113 mean on a Mazda?
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.
P0113 is a standardized OBD-II code, so its definition is the same on every Mazda. What differs by model and engine is which cause is most likely — pick your Mazda model below for a diagnosis tuned to its known failure patterns, recalls, and TSBs.
Is it safe to drive a Mazda with P0113?
In most cases a Mazda 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. Exact tolerance depends on the model and engine.
What causes P0113 on a Mazda?
| 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 |
Repair costs are typical US ranges and vary by Mazda model, model year, and labor rate. A diagnostic trouble code is a symptom, not a guaranteed failed part — confirm the root cause before replacing anything.

What does diagnostic trouble code P0113 mean on a Mazda?

P0113 is a standardized OBD-II code, so the definition is the same on every Mazda — which cause is most likely varies by model and engine.
What are the symptoms of P0113 on a Mazda?
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
