P0113 — Intake Air Temperature (IAT) Sensor Circuit High Input

P0113 means the Intake Air Temperature sensor is reporting an unrealistically high voltage (suggesting very low temperature). Usually a faulty sensor or wiring issue.

Cost range: $20–$200. Severity: low. Safe to drive? Yes, minimal drivability impact.

Most common causes of P0113

1. Faulty IAT sensor — Cheap part, easy swap. Often built into MAF. ($20–$150)
2. Open or shorted wiring — Inspect connector and harness. ($20–$100)
3. Bad PCM connection — Rare — check sensor and wiring first. ($50–$200)

Symptoms drivers report with P0113

• Slight cold-start hesitation
• CEL
