Intake Valve Control Solenoid Circuit Intermittent Bank 1
on 2020 Ford Focus 2.0L I4 · FWD
What this code means
The intake valve control solenoid on Bank 1 has an intermittent electrical fault. Continuous VVT systems use this solenoid to control cam phasing oil flow.
Symptoms
- Check Engine Light comes and goes
- Intermittent rough idle
- Sporadic power loss
- Variable valve noise
- Inconsistent fuel economy
Common causes
- Loose solenoid connector
- Wiring chafing against engine
- Solenoid internal intermittent failure
- Thermal expansion causing contact loss
- Corroded pins
Diagnostic steps
- Monitor VVT solenoid command vs cam position
- Wiggle test on solenoid connector
- Inspect wiring harness routing
- Check connector pin tension
- Test solenoid at operating temperature
Repair notes
Repair connector or replace VVT solenoid. Re-route wiring away from heat sources.
