INJECTOR WIRING & code P0477

[hoogkar]

Does it mater which wire goes to each post on any individual injector -does polarity matter?



Code p0477 - EXHAUST PRESSURE CONTROL RELAY LOW - WHAT DOES THIS DO AND WHERE IS THE RELAY?

polarity doesn't matter on the injector lugs. .

not sure what the exhaust pressure relay problem is. . i am guessing it has to do with your exhaust brake and its wiring to the ecm for automatic actuation
