Question

2003 Ford Focus CMax, what does the engine code P2206 mean?

Answer 1

Hi there

This code means the knox sensor heater control circuit has a problem. In most cases the problem is actually with the sensor itself. The heater element in the sensor is the likely culprit and once replaced the problem is resolved. If the sensor is not the issue, then it's a problem either with the wiring or the computer.
