How severe is this DTC?
The severity of this code is normally moderate, but P2283 can be severe and cause internal engine damage if not corrected in a timely manner.
What are some of the symptoms of the code?
Symptoms of a P2283 trouble code may include:
- Engine may not start
- Low fuel pressure
- Low oil pressure
- Check engine light illuminated
What are some common causes of the code?
Causes
of this P2283 code may include:
- Faulty injector control pressure sensor
- Malfunctioning oil pump
- Defective fuel pump
- Low oil or fuel level
- Faulty or damaged wiring
- Loose or faulty control module ground strap
- Corroded, damaged, or loose connector
- Faulty fuse or fuse link (if applicable)
- Faulty PCM
What are the troubleshooting steps for P2283?
The first step in troubleshooting any malfunction is to search for Technical Service Bulletins (TSBs) for the specific vehicle by year, model, and powertrain. In some circumstances, this can save you significant time in the long run by pointing you in the right direction.
The second step is to check the oil and fuel levels to ensure they are adequate. Then locate all components associated with the injector control pressure sensor circuit and look for obvious physical damage. Perform a thorough visual inspection to check that the associated wiring shows no obvious defects such as scraping, rubbing, bare wires, or burn marks. Next, check connectors and connections for security, corrosion, and damaged pins. This process should include all wiring connectors and connections to the injector control pressure sensor, PCM, and fuel pump. Consult vehicle-specific technical data to see if a fuse or fuse link is incorporated into the circuit.
Advanced Steps
Advanced steps become very vehicle-specific and require appropriate advanced equipment to perform accurately. These procedures require a digital multimeter and vehicle-specific technical references. In this situation, a fuel and oil pressure gauge may be the ideal tool to facilitate the troubleshooting process.
Voltage Checks
A reference voltage of approximately five volts is normally supplied to the injector control pressure sensor from the PCM under most circumstances. The reference voltage and acceptable ranges may vary depending on the specific vehicle and circuit configuration. Specific technical data will include troubleshooting charts and the proper sequence to follow to help you establish an accurate diagnosis.
If this process identifies the absence of a power source or ground, continuity tests may be required to verify the integrity of the wiring, connectors, and other components. Continuity tests should always be performed with the power disconnected from the circuit, and normal readings for wiring and connections should be 0 ohms of resistance. Resistance or lack of continuity is an indication of faulty wiring that is open or shorted and must be repaired or replaced. A continuity test from the PCM control to the chassis will confirm the serviceability of the ground straps and wires. The presence of resistance indicates a loose connection or possible corrosion.
What are the common repairs for this code?
- Adding oil or fuel
- Replacing the injector control pressure (ICP) sensor
- Replacing the fuel pump
- Replacing the oil pump
- Cleaning corrosion from connectors
- Repairing or replacing faulty wiring
- Replacing a blown fuse or fuse link (if applicable)
- Repairing or replacing faulty ground straps
- Replacing the PCM
Common Mistake
Replacing the injector control pressure sensor or fuel pump when faulty wiring is causing this issue.
