Step-by-Step Fix Protocol for 2019 Tesla Model 3
Connect an OBD-II scanner to the DLC port under the driver dashboard. Record engine RPM, Short Term / Long Term Fuel Trim (STFT/LTFT), and engine coolant temperature at the moment P0460 set.
Inspect the sensor connector on the 2019 Model 3 engine bay. Use a multimeter to verify reference voltage (5.0V / 12.0V) and ground continuity.
Replace the verified defective component using OEM or equivalent grade parts. Clear DTC P0460 and complete an EPA drive cycle to verify readiness monitors set to READY.
