How is fault code P0517 fixed?

A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Scan the car and confirm P0517 is actually stored, then note any other codes sat alongside it, charging faults like P0562 often turn up together and point you at the same area 2. Get your eyes on the sensor connector and the wiring around the battery. Look for green corrosion, chafed insulation, and pins that have backed out of the plug 3. Measure the sensor's resistance with a multimeter and check it against the manufacturer's figures for the temperature it's sitting at, a sensor reading open or wildly off needs replacing 4. Check the circuit wiring for continuity and that it's getting its proper reference voltage, this catches the broken wire that a quick visual misses 5. Watch the live sensor data on the scanner. If the reading is pinned at maximum or jumping around when nothing's changing, that confirms the circuit fault 6. Only if the sensor and every bit of wiring check out should you start considering the ECM, and that's a last resort
