• Problems with the lambda probe heater relay

How to Fix

1. Connect the diagnostic scanner and read the error codes
2. Check the oxygen sensor heater circuit fuses.
3. Measure the resistance of the sensor heating element (should be 2-14 Ohms)
4. Check the integrity of the wiring from the ECU to the sensor
