Intake air temperature circuit high input
The controller saw intake-air-temperature circuit voltage corresponding to an implausibly cold value or an open/high-input condition.
Conditions that can produce P0113
These are diagnostic branches, not a ranked parts list. Prevalence and testing order depend on the exact vehicle and failure scene.
- Disconnected sensor or spread terminal
- Open signal or sensor-ground circuit
- Failed temperature element
- Connector contamination or harness damage
- Incorrect component or pinout
What to inspect next
- Compare intake temperature with ambient and coolant after a cold soak
- Inspect connector fit and shared sensor ground
- Use exact circuit voltage and resistance specifications
- Confirm whether the temperature element is part of another sensor assembly
Evidence that strengthens the answer
Verify the repair
Preserve the pre-repair record, document exactly what changed, then repeat the relevant operating condition safely. Confirm no current or pending fault returns, review permanent-code and readiness state where applicable, and state which tests or modules remained unavailable.
This page explains a commonly standardized code at a general level. Confirm the exact definition, module, status, test conditions, thresholds, wiring, and service process for the vehicle application using current official information.
