CEL Error code P216A
Common Problems That Trigger the P216A Code
- Fuel injector failure
- Powertrain Control Module (PCM) failure
- Wiring issue
P216A says that the injector is not getting supply voltage. Might check to see if the plugs to all the injectors are connected.
Edit: If they are all plugged in, then unplug them one at a time, with the ignition switch in the run position but engine not started or running, check the pin with the red wire for voltage on each injector plug.
