P02C5 - OBD Trouble Code

<<See All OBD Codes

The OBD code P02C5 can be defined as cylinder 11 injector leaking. It is a generic powertrain diagnostic fault code which would apply to all the OBD-II vehicles. The exact repairing steps can always vary depending upon the year, make, model as well as the configuration of the powertrain.

Is your overall engine performance decreasing and there is an increase in the fuel consumption? Are there some failure issues in the fuel injector or the powertrain control module? Or are there some faults in the mass air flow or manifold air pressure (MAP) sensor? If you are facing all these issues, then P02C5 fault code is definitely going to trigger up.

Searching great information about the P02C5 code? Then you have arrived at the correct place. The engine control module would use a fuel pressure sensor to determine the amount of fuel pressure which is present in the fuel rail. If the fuel pressure does not change the way the powertrain control module thinks it should, then the P02C5 fault code would be set.

This fault code should be classified as severe because a lean fuel condition can cause the cylinder head to even sometimes damage to the car engine.

What causes this problem with the Cylinder 11 - Injector Leaking

• There can be faulty or clogged fuel injector
• The issue of opened or shorted fuel injector circuit
• Defects in the oxygen sensor
• Powertrain control module programming error
• Mass air flow or Manifold Air Pressure sensor failure

1. Fuel Injector - Faulty Fuel Injector can cause a lot of issues like displaying P02C5 fault code. Thus, replace it immediately.
2. Fuel Pump - OBD Code P02C5 can flash if the Fuel Pump is damaged. You must replace it with a brand new one online with us.
3. Oxygen Sensor - Is your fuel pump perfectly correct, but still seeing P02C5 code? Then there is definitely some issue with the Oxygen Sensor.
4. Manifold Air Pressure (MAP) sensor - Did your mechanic just found out that there is some fault in the Manifold Air Pressure (MAP) sensor? Buy top notch Manifold Air Pressure (MAP) sensor from us at economical prices.
5. Powertrain Control Module - A broken Powertrain Control Module can cause a lot of issues. It would be nice if you get it replaced on time.

Willing to know some common symptoms of OBD Code P02C5? Your wish is our demand. Have a look at them below:

Common Symptoms

• Decrease in the amount of engine performance
• Overall fuel efficiency can start diminishing
• The engine start up can be delayed
• There can be presence of stored rich exhaust codes
• Some misfire codes may also be stored

Here are some ways with the help of which you will be able to correct the OBD Code P02C5

• You must replace the fuel injector

The codes which are related to MAF and MAP should be diagnosed and properly repaired before attempting to diagnose a code P02C5. You must begin your diagnosis with a general inspection of the fuel injection rail area. You must carefully inspect the outside for signs of corrosion and leakage. If there is heavy corrosion on the exterior of the fuel injector, or if it is leaking, suspect that it has failed. If you find out that there are no obvious mechanical issues in the engine bay, there are several tools that will be required for an accurate diagnosis:

• A digital volt/ohmmeter
• A diagnostic scanner
• An automotive stethoscope
• A reliable vehicle information source 

After that you should connect the scanner to the vehicle diagnostic port and retrieve all stored codes and freeze frame data. It would be very helpful as the diagnosis would start unfolding. Then clear the codes and test-drive the vehicle to see if the P02C5 is reset. If the fault code P02C5 immediately returns, use the scanner to perform an injector balance test to verify that the misfire is an injector problem. Once you have done so, then you should proceed to step 1.

Now when the car engine is running, use the stethoscope to audibly monitor the fuel injector in question. An audible clicking sound should be heard and repeated in pattern. If the sound is not present, at all, then you should proceed to step 2. If it is strained or intermittent, suspect that the injector for cylinder #11 has failed or is clogged. You should compare the sounds from that cylinder injector to others for comparison, if required. After that you should use the DVOM to test for voltage and a ground pulse, when the engine is running. Most manufacturers utilize a system of constant battery voltage on one terminal of the fuel injector and a ground pulse applied to the other terminal at the appropriate time.

If you find out that there is no voltage at the connector of the fuel injector in question, use the DVOM to test system fuses and relays. The fuses should be replaced and relays as needed. The fuses with the circuit under a load should be tested. A defective fuse that seems good when the circuit is not loaded may fail with the circuit loaded. Now if all system fuses and as well as relays are in good working condition and there is no voltage present, then you should use your vehicle information source to trace the circuit back to the ignition switch or fuel injection module.

Common Mistakes When Diagnosing The P02C5 Code

• Some faults in the fuel injector
• The powertrain control module failure
• There can also be some wiring issue
