What Does P216F Mean?
The PCM has detected abnormally high voltage in the power supply circuit feeding fuel injector group F. This typically indicates an open circuit, poor ground connection, or driver circuit issue in the PCM.
Safety Warning
Engine will run rough or not start due to inactive injectors. Vehicle may stall unexpectedly or exhibit severe lack of power.
Common Causes
30%
Open circuit in injector wiring harness
25%
Poor ground connection at injector or engine harness
20%
Disconnected or corroded injector connector
15%
Failed fuel injector with open coil
10%
Faulty PCM injector driver circuit
Diagnostic Steps
1
Step 1: Verify all injector connectors for group F are properly connected and not damaged
2
Step 2: Check continuity of injector power supply circuit from PCM to each injector
3
Step 3: Test ground circuits for proper continuity and resistance (should be less than 1 ohm)
4
Step 4: Measure injector coil resistance and compare to manufacturer specifications
5
Step 5: Monitor injector command signal with scan tool or oscilloscope while cranking
Estimated Repair Cost
$150 - $1,200
Parts + labor, varies by vehicle and location
The PCM has detected abnormally high voltage in the power supply circuit feeding fuel injector group F. This typically indicates an open circuit, poor ground connection, or driver circuit issue in the PCM.
The most common cause of P216F (Fuel Injector Group "F" Supply Voltage Circuit High) is: Open circuit in injector wiring harness
Typical repair costs for P216F range from $150 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Engine will run rough or not start due to inactive injectors. Vehicle may stall unexpectedly or exhibit severe lack of power.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P216F to identify the root cause.
