Question

P0136 -where is located this sensor in 2000 Ford Explorer 4.0L in Mexico?

Answer 1

Hi there,

This code is telling us there is a problem with the heated O2 sensor heater circuit. Sadly ALL of the O2 sensors are included in this code. It's not that they are all bad, but the code isn't specific to the one sensor that is bad. Best to use a scan tool that can see the live data and determine which sensor is the problem.
