P0113 on a Jeep: Causes, Fixes & Repair Cost
🟢 Low severity · drivable
Safe to drive — the engine just reads intake air temperature wrong, which may cause slightly rich running.
What P0113 means on a Jeep
On a Jeep, P0113 means the intake air temperature (IAT) sensor is sending a high-voltage, open-circuit signal. On many Jeeps the IAT sensor is a separate unit in the intake tract near the air box, while some models build it into the mass air flow sensor. The engine may run slightly rich until it is fixed.
Is P0113 common on Jeeps?
P0113 is common on Jeeps where the IAT sensor, its connector, or its wiring sits exposed in the engine bay and wears over time. Off-road use can also knock the connector loose or damage the wiring. It is a sensor fault, not an engine failure.
Commonly reported on: Wrangler, Cherokee, Grand Cherokee, Compass.
