The P216E: Fuel Injector Group ‘F’ Supply Voltage Circuit Low refers to a condition where the voltage supplied to fuel injector group ‘F’ is lower than expected. This can be caused by low voltage in the circuit, faulty injectors, or issues with the wiring or power supply.
P216E – Quick Overview
| Code | Information |
|---|---|
| Meaning | P216E: Fuel Injector Group ‘F’ Supply Voltage Circuit Low |
| Is it serious? | Yes, this can cause performance issues such as misfires, poor fuel injection, or difficulty starting the vehicle. |
| Possible causes | – Low voltage in the fuel injector group ‘F’ supply circuit – Faulty fuel injector group ‘F’ – Wiring or power supply issues |
| How to diagnose? | – Measure voltage in the fuel injector group ‘F’ supply circuit – Test the fuel injector group ‘F’ – Inspect wiring and connections for faults |
P216E Meaning
The P216E: Fuel Injector Group ‘F’ Supply Voltage Circuit Low code indicates that the engine control module (ECM) has detected a lower-than-expected voltage in the supply circuit for fuel injector group ‘F’. Low voltage can result in improper fuel injection, causing poor engine performance, rough idling, or misfires. It is crucial to maintain proper voltage to ensure the injectors function as intended.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional related codes that could offer more insight into the problem. | OBD-II Scanner |
| Measure Voltage in Supply Circuit | Use a multimeter to measure the voltage in the fuel injector group ‘F’ supply circuit. Ensure the voltage is within manufacturer specifications and not too low. | Multimeter, Vehicle Manual |
| Test Fuel Injector Group ‘F’ | Use a diagnostic tool to test the functionality of the fuel injectors in group ‘F’. Check that they are receiving proper voltage and are functioning correctly. | Multimeter, Diagnostic Tool |
| Inspect Wiring and Connections | Visually inspect the wiring and connections leading to the fuel injectors for signs of damage, loose connections, or corrosion that may cause low voltage. | Flashlight, Safety Gloves |
| Check Power Supply | Ensure the power supply to the injectors is adequate. Inspect the voltage regulator and related components for faults that could lead to low voltage. | Multimeter, Wiring Diagram |
| Repair or Replace Faulty Components | Repair or replace any faulty wiring, connectors, or injectors to resolve the low voltage issue. | Replacement Parts, Tools |
| Clear the Code and Test Drive | After repairs, clear the P216E code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure that the P216E code does not return. | OBD-II Scanner |
