A P008C trouble code is related to a diesel engine’s fuel cooler pump designed to maintain colder fuel temperatures.
P008C is an OBD-II code for a open circuit problem with the fuel cooler system. This code is illuminated to alert the driver that a connection among the controller circuit is broken, either from an unplugged connector, damaged connector, or damaged wire.
The most common causes for a P008C are:
A P008C will typically not cause any noticeable symptoms other than a check engine light. In some cases, it can cause surging acceleration from a lack of fuel cooling.
Your mechanic will start with a visual inspection of the fuel cooler system, looking for unplugged connections and or damaged wiring, repairing as necessary. If connections and wiring appear to be in good condition, your mechanic will test the wiring and connectors using a digital multi meter. If a fault in the voltage is found, that section of wiring or connection will be replaced. If not, it may be necessary to replace the fuel cooler pump itself.
A P008C may be an intermittent issue from wear and tear. Getting rid of the code may be as simple as clearing it, running fuel treatment, and resetting the engine computer.
Hot fuel temperatures are not desirable and can cause excessive wear on other fuel components. They can also cause poor acceleration which can be dangerous.
The most common repairs for a P008C are as follows:
P008C codes are exceptionally common with Ford Powerstroke diesels, and even more so with the 6.4 liters from 2008 through 2010.
