Injector Control Pressure Sensor Circuit Intermittent
The P2287 code indicates that the Engine Control Module (ECM) has detected an intermittent signal from the injector control pressure (ICP) sensor. This sensor monitors the high-pressure oil system that actuates the fuel injectors in diesel engines. An intermittent circuit can cause erratic fuel delivery, leading to performance issues. Common causes include wiring harness damage, loose connectors, sensor failure, or oil contamination in the sensor.
01. Most Common Causes
- Faulty injector control pressure sensor
- Damaged or corroded wiring/connectors
- Intermittent open or short in the sensor circuit
- Oil contamination in the sensor or connector
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine hard starting or no start
- Rough idle or misfire
- Loss of power or poor acceleration
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the ICP sensor and wiring for damage, corrosion, or loose connections.
Step 3: Test the ICP sensor voltage and resistance with a multimeter; compare to manufacturer specs.
Step 4: Check for oil leaks around the sensor and connector; clean if necessary.
Step 5: If intermittent, perform a wiggle test on the wiring harness while monitoring sensor signal.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with this code, as it can cause stalling, hard starting, or loss of power, which may lead to unsafe driving conditions.
How much does it cost to fix?▼
The cost to fix P2287 typically ranges from $50 to $150 for diagnosis and sensor replacement, but can be higher if wiring repairs are needed.
