Description
P0201 Cylinder 1 Injector Circuit Malfunction
P0202 Cylinder 2 Injector Circuit Malfunction
P0203 Cylinder 3 Injector Circuit Malfunction
P0204 Cylinder 4 Injector Circuit Malfunction
P0205 Cylinder 5 Injector Circuit Malfunction
P0206 Cylinder 6 Injector Circuit Malfunction
The PCM has detected a fault in the injector or the wiring to the injector
Symptoms
The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.
Causes
The causes could be any of the following:

The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.
Causes
The causes could be any of the following:
- Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
- Open in the wiring to the injector
- Short in the wiring to the injector
- Bad PCM
- With a Digital Ohm meter check the resistance of the injector. If it isn't within specs, then replace the injector.
- Check for voltage at the fuel injector connector. It should have battery voltage.
- Inspect the connector for damage or broken wires.
- Inspect the injector for damage.
- Swap the injector with another one and see if the code changes. If the code changes, then replace the injector.
- At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you're not sure, do not attempt) The injector should activate
