Injector Control Pressure Too High
This trouble code will only be found on diesel engine equipped vehicles. This trouble code indicates that the oil pressure has risen to a point that is beyond the range of acceptance set by the manufacturer. If this code is stored in your vehicle, it is not wise to drive the vehicle until the issue has been resolved as the engine may suffer serious damage.
Some of the potential causes of this trouble code may include:
Lack of oil changes or low oil level may contribute to this issue.
A faulty oil injector pressure sensor may also contribute to this issue.
A faulty oil pressure regulator may exist.
A damaged wiring harness or connector that is associated with any part of the high pressure oil injector circuit may be present.
The powertrain control module could be malfunctioning although this is unlikely.
Some of the symptoms of this trouble code that the driver may experience would include:
The Check Engine Light will likely be illuminated.
If the engine is not turned off at the earliest possible opportunity, the engine may suffer very serious damage.
The red oil pressure light may also be illuminated and should be taken as a signal that the oil pressure is low and the engine should be turned off.
A mechanic may diagnose this trouble code by checking the condition and level of the engine oil. Then the mechanic would then check the oil injector pressure sensor and its circuitry for any damages. Next, the mechanic would check and test the oil pressure regulator using the manufacturer’s suggested procedure. As long as no other issues are present, the mechanic would finally test the powertrain control module for proper function with a high tech scan tool. If any issues are found during the diagnosis of this issue, they should be resolved before any further diagnosis takes place.
A common mistake that could be made when diagnosing this trouble code would be forgetting to check the oil prior to any further diagnosis. The condition and level of the engine oil is a vital piece of information that is needed when determining the reason that this trouble code is stored in the vehicle’s powertrain control module.
This trouble code would be considered very serious as it can destroy the engine if it is ignored. This issue should be diagnosed and repaired at the earliest possible opportunity in order to prevent serious engine damage.
Repairs that can potentially resolve the issues caused by this trouble code may include:
Replacing the oil pressure regulator
Repairing or replacing any wiring or connectors that are associated with the oil pressure circuit
Replacing the powertrain control module
Once again, please do not fall victim to the serious engine damage that low oil pressure can cause. Have regular oil changes performed on your vehicle and fix oil leaks as soon as possible to ensure that the condition and level of the oil are always where they should be. Basic maintenance can prevent trouble codes such as this one.
