Ford Repair Questions? Ask a Mechanic for Answers ASAP
Good evening, if you reset the codes which ones will come back right away. Because out of that bunch we have 2 for cylinders which is likely an injector issue.. Two for exhaust backpressure sensor one for the MAP sensor and 2 for the charging system.
p0278 is cylinder 6 and P0472. This list of codes will likely be do to a 5 volt reference shorting. There are multiple sensors or wires that could short this reference voltage, however, the ICP sensor and connector should be inspected first. Look for wiring damage at or near the connector. Repair and/or replace as necessary. . The next place to look would be at the exhaust backpressure sensor, many times the sensor will be shorted or you will see the wiring chafed or damaged. Then look near the EGR valve, in some cases there will be damaged or chafed wiring. If there are no visible signs of damage, begin unplugging the 5 volt reference components to isolate the short. I think this happened when they did the injectors and it is possible they have a wire stuck inside the valve cover. This should be covered under the job they did.
No problem glad to be of assistance. Charlie.
