p2146
I've got a '06 dodge with a p2146 logged and active. became active when the truck was under hard acceleration and going up a hill. My question is when this code is active does the e.c.m. cut out the front 3 cylinders until the code is cleared? The reason I ask is the voltage on the front 3 cylinders was .156 volts d.c. at the injector and also at the wiring connector at the valve cover gasket. any help would be greatly appreciated. the truck is stock no bombing yet

Remove the valve cover, unplug the injector harness for the front bank where it plugs in at the valve cover gasket/injector harness connector and remove the harness wires from the front three injectors. Using an ohm meter check across the terminals of each injector one at a time. Each injector should have a resistance of 0-1 ohm. If the resistance is higher than one ohm it will set this code, and that injector needs to be replaced. An injector is by far the most likely cause, followed by the valve cover gasket/injector harness.
