Error Code P216C: What It Means & What To Do?
OBD Code P216C - Fuel Injector Group E Circuit High
Improper fuel-air ratios can lead to loss of
engine power, loss of acceleration and stalling as well as rough idle problems
along with check engine light illuminating. This can be due to P216C error
indicating problem with fuel injection system of the vehicle.
Learn More About OBD Error Code P216C
OBD code P216C Fuel Injector Group E Circuit High gets stored if the ECM (Engine Control Module) detects the fuel injector circuit showing high voltage input.
The ECM monitor the fuel injectors learning values and if it notices that they are beyond normal operating parameters, it sets P216C. Most of the time, this code is being set because something has caused the injector to exhaust its adaptability. This usually means that for one reason or another, the ECM is trying to modify the fuel mixture according to driver's needs but something is causing the fuel injector circuit showing high voltage input.
What causes this problem with the Fuel Injector Group E Circuit High?
- Plugged/dirty fuel filter
- Fuel pump cracked
- Powertrain control module failure
- Fuel injector damaged
- Wiring and connector issues
- Intake manifold cracked
- Leaking intake, PCV, EGR gaskets
Replace/Repair These Parts To Fix Code P216C
- Engine Control Module - ECM failures and faults
can be very difficult to find and resolve as these are very rare and might
require a complete reprogramming of the system to avoid wrong codes from
getting stored in the system, leading to misdiagnosis. Replace it now!
- Powertrain Control Module - Faulty PCM can disrupt
the normal functioning of the vehicle by affecting the transmission system and
the fuel delivery system. This will cause the system to store wrong OBD error
and thus can lead to misdiagnosis.
- Oxygen Sensor - Inspect for faulty O2
sensor that can affect the engine combustion process and the exhaust emissions.
Thus, it is important to understand its importance and replace faulty oxygen
sensor now!
- Diagnostic Tools - Take help of a
professional mechanic to diagnose OBD code error. Use high grade diagnostic
tools to resolve this issue. Buy new tools and equipment from us!
- Fuel Injector - Bad fuel injectors can
cause starting issues; poor idles and affected performance. Thus, the
replacements are in order. Buy new fuel injectors now!
- Fuel Sender Connector - Always check for faulty
sender connectors as they can hinder the fuel delivery system, leading to lean
or rich engine conditions, causing performance issues. Thus, replace faulty
fuel sender connectors now!
- Spark Plugs - Spark plugs are easy to
replace and are inexpensive too. They help in delivering the electric current
from the ignition system to the combustion chamber of the spark ignition engine
to ignite the compressed air to fuel mixture by an electric spark. Thus,
replace them now!
- Fuel Tank Pressure Sensor - The fuel tank pressure
sensor is part of the fuel pump assembly and is mounted on top of the tank or
inside the tank. It is part of the evaporative emissions system and reads
pressure in the fuel system to detect evaporative leaks, such as a loose or
faulty gas cap. Replace faulty pressure sensor now!

Easy Diagnosis Of Engine Error OBD Code P216C
Here are some steps which you should follow in order to diagnose this P216C fault code:
- Take the help of an experienced mechanic who will visually inspecting the fuel system, searching primarily for the leak. Since the leak is considered a significant one, it should be fairly easy to locate.
- Find and freeze frame data with the code. Then, clear the code and take the vehicle on a test drive under the same conditions.
- If the code reappears, perform a visual inspection of the components and its wiring.
- If the wiring is okay, the injector itself will be tested to confirm operation.
- If the fuel injector of the cylinder 4 is functioning properly, the technician must check for other components of the fuel delivery system for damages and faults.
- The mechanic will repair or replace the part that is causing the large fuel leak, once the source of fuel leak has been found.
- Check for any wiring and harness issues and correct the damaged wirings.
- If there is no problem found, check for the faulty ECU. Although, this fault is very rare but can be a reason for problematic fuel delivery system, thus hampering the engine performance. The ECU needs to be replaced in such condition and has to be reprogrammed to erase any stored faulty error.
Common Mistakes When Diagnosing The P216C Code
Always take professional help and follow the diagnosis instructions properly before coming to a conclusion or simply replacing any components. Check for the following components and system properly before coming to any conclusion to avoid any hefty repair costs that could have been avoided.
- Check for damaged or worn out wirings and connectors to various components for the fuel delivery system and replace them first
- Check for faulty fuel injector and system
- Inspect for PCM failure that can be corrected with reprogramming
- Check for clogged fuel filters and clean of replace as required
