What does code P1113 mean?

Q: What does code P1113 mean?

Oxygen Sensor Heater Resistance Too High Bank 1 Sensor 1. P1113 on Volkswagen vehicles means the engine control module (ECM) measured a heater circuit resistance for the upstream oxygen sensor on bank 1 that is higher than the expected range, indicating a weak or open heater element or a wiring fault. The sensor's heater is responsible for bringing the sensor up to operating temperature quickly so the ECM can enter closed-loop fuel control; when resistance is too high, the heater draws too little current and the sensor may stay cold longer than intended.
