Guide To P216A OBD Error Code Solutions
OBD Code P216A - Fuel Injector Group E Circuit/Open
Is
your vehicle’s Check Engine Light illuminated? Are you experiencing sudden
decrease in engine power and acceleration? Is there a drop in the fuel economy
with increased level of emissions? All these indicate problem with the fuel
delivery system and the Powertrain Control Module, thus flashing OBD Code P216A
error.
Learn More About OBD Error Code P216A
If the PCM notes that the learning values of the fuel injector is beyond normal operating parameters, it sets OBD Code P216A error in the system. This usually means that the injector for the Group E is in no more capacity to adapt to the changing requirements of the engine as per the external environment and the driver’s needs.
What causes this problem with the Fuel Injector Group E Circuit/Open?
- Leaky/damaged fuel injector
- Poor fuel pump
- Leakage in the engine vacuum
- Some fault in the oxygen sensor
- Mass air flow or manifold air pressure sensor failure
- PCM failure
Replace/Repair These Parts To Fix Code P216A
- Engine Control
Module - It is not always the components, but the ECM that can
also be faulty. It can cause misinterpretation of correct data thus leading to
wrong operational decisions which will affect the transmission and overall
engine performance. Thus, replace faulty module and reprogram it now!
- Powertrain Control
Module - Powertrain Control Module can also be faulty in rare
cases and thus needs through checks for system and software errors. Thus check
and replace it, if required.
- Diagnostic Tool
- It is always advisable to use correct tools and equipment while resolving
any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus,
always take help from a professional who has the knowledge and experience to
such tools in efficient manner. Buy new quality diagnostic tools from us today!
- Fuel Injector - The fuel injectors are important component of the fuel delivery system that
helps in proper utilization of the fuel entering the engine. This not only
helps in taking care of the air to fuel ratios in the engine, helping the
combustion process but also enhances the performance. Thus, replace faulty
injector now!
- Engine Wiring Harness - Most of the time, a particular component doesn’t work properly due to faulty
wiring and connectors. These need to be replaced immediately as it can easily
solve any OBD code problem. Buy and replace faulty wiring harness today!
- Fuel Sender
Connector - The fuel sender connector is responsible for
optimising the fuel flow into the engine and if found faulty, will cause
problems in fuel delivery. Thus, it needs to be replaced immediately.
- Spark Plugs - Most of the time, the spark plugs protect the devices from getting damage and
help in ignition process by regulating the current. These are usually easy to
replace and are very cheap solution to any OBD problem. Thus, replace the
faulty ones now!
- Oxygen Sensor - If the fuel to air ratio is not correct, the engine may work in lean or rich
conditions. This not only hampers the performance output, but also affects the
fuel economy, exhaust emissions and acceleration. Thus, a faulty oxygen sensor
must be replaced as if it important for keeping in check the oxygen levels
entering/exiting the engine.
- Fuel Tank Pressure
Sensor - The fuel tank must maintain proper pressure to the fuel
to mix well with the oxygen, for proper combustion as it enters the engine for
combustion process. Also, it ensures a consistent supply of fuel to the engine
for combustion. Thus, replace faulty sensor now!

Easy Diagnosis Of Engine Error OBD Code P216A
If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:
Locate your fuel injector which usually is pretty simple to find and do a proper visual inspection. Make sure to ensure that there is no fuel leakage in the fittings and connectors. Also, the injector itself (o-ring) is a common leak. Inspect for any signs of physical damage or anything that would cause fuel flow to be reduced (i.e. kinked line at injector). Clogging of particles within the fuel is a real possibility given the openings being very small. Ensure proper fuel system maintenance (e.g. fuel filters, EVAP, etc.)
Follow the diagnostic steps as follows;
- Make sure if P216A is active, the temperature is reasonable out. If it is extremely cold out, you may want to let the car warm up adequately first, then clear codes and drive vehicle to see if it comes active again. Sometimes, the elements around us are extreme enough to make even the most reliable make and model malfunction somehow.
- Make sure if there are any leaks, to address them immediately. Make use of automobile stethoscope to listen to the problem properly. This can and will cause lower than desired fuel pressures in any closed system so ensure the system is properly sealed and not actively leaking anywhere. Rusted lines, fuel filter gaskets, deteriorated o-rings, etc. all cause fuel leaks.
- Check your low fuel pressure system's filter. These may be located on the frame rail or close to the fuel tank. It should be fairly evident if the fuel filter has been replaced recently or if it looks like it has never been changed (or not for a while). Replace accordingly. Keep in mind, Introducing air into a diesel fuel system can be a tricky problem to rectify so make sure you follow proper bleeding and filter replacement procedures. Refer to service manual for specifications and procedures.
- Locate your fuel injector. These usually are pretty simple to find but that said, sometimes plastic covers and other brackets may be in the way of proper visual inspection. Make sure to ensure no fittings or connectors are leaking fuel. Also, around the injector itself (o-ring) is a common leak. Visually inspect for any signs of physical damage or for that matter anything that would cause fuel flow to be reduced (i.e. kinked line at injector). Particles within the fuel is a real possibility given the openings being so small. Ensure proper fuel system maintenance (e.g fuel filters, EVAP, etc.)
Common Mistakes When Diagnosing The P216A Code
Most of the time we tend to diagnose the problem without completely identifying the real cause of it. It is important to follow all the diagnostic steps and examine each component carefully before correcting. Some of the components to be focused on are listed below;
- Clogged fuel filter
- Fuel pressure regulator failure
- Fuel pump failure
- Leaking fuel lines
- Powertrain Control Module (PCM) failure
- Wiring/harness issue
