Question about Jeep Grand Cherokee
The only V6 engine I could find in a Cherokee was in the mid 1980s and it was carb not fuel injected. The 4.0 straight 6 engines that were fuel injected used the same black wire for all 6 injectors to power them. Each injector has a different ground wire from the computer.
The injector in question should have the same input voltage as the others and then a ground signal on the other side when the computer commands it to open. All 6 injectors should also have the same resistance when the harness is unplugged.

Yes, the code will need to be cleared by the technician.
Usually the check engine light doesn't come back on immediately. However it will store the code until it is cleared by the tech.
If it comes back on immediately, then you have an immediate problem b/c it take a certain number of misfires over a certain number of miles before it trips the code again.

Before changing you pcm try cleaning your egr valve. remove the valve and see if its stuck in the open position if so use a small pick to clean around the spring.
