P0113 on a Volkswagen: 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 Volkswagen
On a Volkswagen, P0113 means the intake air temperature (IAT) sensor is sending a high-voltage, open-circuit signal. On many VWs the IAT sensor is built into the mass air flow (MAF) sensor, while some models use a separate sensor in the intake boot. The engine may run slightly rich until it is fixed.
Is P0113 common on Volkswagens?
P0113 is common on Volkswagens as the MAF/IAT sensor ages and its element gets contaminated with oil and dirt from the intake. A cracked or loose intake boot can also let the connector or wiring move and fail. It is a sensor fault, not an engine problem.
Commonly reported on: Golf, Jetta, Passat, Tiguan.
