Voltage/Resistance: Solenoid resistance ~ 0.5–2 Ω (check with a multimeter).

2. Installation Steps:
Clean the rail and mounting holes to prevent contamination.
Torque to spec (typically 25–30 Nm).
Post-installation: Perform injector adaptation and clear DTCs via diagnostic tool.

 

 

Break-in Period
Post-installation requirements:
① Avoid sudden acceleration within 50km
② Replace fuel filter after first 500km

 

3. Testing & Maintenance Tips
Testing Methods:
Resistance Check: Disconnect the plug, measure solenoid resistance (abnormal = coil damage).
Leakage Test: Check return fuel volume per injector on a test bench (replace if uneven).
Waveform Analysis: Use an oscilloscope to verify drive signal integrity.

 

Repair Recommendations:
Cleaning: Ultrasonic cleaning for minor carbon buildup.
Seal Replacement: Always use OEM copper washers/O-rings to prevent leaks.
Coding: New injectors require calibration codes (e.g., Bosch KTS or dedicated tools).
