P0113 Toyota Code - Intake Air Temperature Circuit High Input

Quick Answer

The P0113 diagnostic trouble code (DTC) for Toyota vehicles indicates that the Engine Control Module (ECM) has detected a high voltage input from the Intake Air Temperature (IAT) sensor circuit. Common causes include Faulty IAT sensor, Wiring issues or a short circuit in the IAT sensor circuit, Corrosion or poor connections at the sensor or ECM. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0113 Toyota Description

The P0113 diagnostic trouble code (DTC) for Toyota vehicles indicates that the Engine Control Module (ECM) has detected a high voltage input from the Intake Air Temperature (IAT) sensor circuit. The IAT sensor is responsible for monitoring the temperature of the air entering the engine, which is crucial for fuel mixture and ignition timing control. A high input signal from the IAT sensor can lead to incorrect fuel delivery, timing adjustments, and overall engine performance. This can result in decreased fuel efficiency, rough idling, poor acceleration, and potential engine misfires.

  • You now have to check if the fuel pump is working. Does the fuel pump gets 12V at the connector?

  • 2013 camry cranks no start. have fuel and spark but also have p0102 and p0113 codes. changed MAF sensor and still won't start.

  • Do you still get the codes after you change the MAF? did you used a new or used sensor?

    Reply to Comment

  • Used a new sensor. Still have the codes.

  • I checked a national database of repairs for your model year, and other than the MAF there are no other repairs. Your next step is to check the wires from the Engine Control Module (ECM) to the MAF. Make sure you inspect the new MAF for damage connector.
