Check engine code p0300 - Ranger Ford Cars & Trucks

SOURCE: code p0300 and p1406

P0300 is misfire and p1406 is EGR. It sounds like you have a chunk of carbon stuck in the EGR valve. Remove the valve and clean the carbon from the valve, bottom side. Then install a screened gasket so it won't happen again.

All of these codes are misfire codes.clicking sound is most likely spark jump from plug wires to metal(head,block,valve cover etc.)

P0300 is a Random Misfire
P0302 #2 Cylinder Misfire
U1120 The code U1120 means, lost wheel distance message. The powertrain control module(PCM) is not
receiving a signal from the anti-lock brake module. The problem could be a short in the bus circuit,
the PCM or the anti-lock brake module. This type of problem is best diagnosed by the dealer or a
local shop with the proper diagnostic scanning equipment. Hope this helps.
