Injector Control Pressure Sensor Circuit Intermittent
The P2287 code indicates an intermittent fault in the injector control pressure (ICP) sensor circuit. The ICP sensor monitors high-pressure oil in the fuel injection system, critical for proper injector operation. An intermittent signal can cause erratic fuel delivery, leading to performance issues. Common causes include wiring damage, loose connectors, sensor failure, or oil contamination.
1. Most Common Causes
- Faulty ICP sensor
- Damaged or corroded wiring/connectors
- Intermittent short or open in the circuit
- Oil contamination in the sensor or connector
2. Symptoms You Will Notice
- Check Engine Light on
- Hard starting or no start
- Rough idle or misfire
- Reduced power or hesitation
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect ICP sensor and wiring for damage, corrosion, or loose connections.
Step 3: Test ICP sensor signal voltage with a multimeter while wiggling harness to reproduce intermittent fault.
Step 4: Check for oil leaks at sensor and connector; clean or replace as needed.
Step 5: If wiring and sensor appear good, replace ICP sensor and clear codes.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended as intermittent loss of injection control pressure can cause sudden power loss or stalling, posing a safety risk.
How much does it cost to fix?▼
Diagnosis typically costs $50-$150. Replacing the ICP sensor adds $100-$300 for parts and labor, depending on vehicle.
