Intake Camshaft Position Timing Over-Retarded (Bank 1)

Intake camshaft timing is over-retarded. Usually caused by a clogged VVT oil control valve or low oil level. Replace the OCV (Denso) and change oil with 0W-20 synthetic. If the code persists after OCV replacement, the timing chain may have jumped a tooth. Check cam-to-crank correlation with a scan tool. Confirm the exact part for your year and engine with a retailer's fitment lookup or your VIN before ordering - these applications split by engine and build date.

Intake cam phaser is stuck retarded. Ford issued a service bulletin for cam phaser noise and timing codes on EcoBoost engines. The cam phaser actuator wears internally and loses oil pressure. Replace both intake cam phasers and the timing chain tensioners. Use only Motorcraft 5W-30 oil and change every 5,000 miles. Your dealer can confirm whether an open service bulletin or warranty extension applies to your VIN.

Intake cam timing over-retarded on the Ecotec 2.4L. This often indicates timing chain stretch rather than just a solenoid issue. Listen for a rattle on cold start lasting 1-3 seconds. If present, replace the timing chain kit including chain, guides, and tensioner. Replace the VVT solenoid as well. Your dealer can confirm whether an open service bulletin or warranty extension applies to your VIN.

Low oil pressure from oil consumption causes the VVT actuator to default to the retarded position. Check oil level first -- Theta II engines burn oil heavily. Replace the intake OCV (Hyundai) and top off oil. Monitor consumption over 1000 miles. If consumption is excessive, engine may need internal repair under Hyundai/Kia settlement. Confirm the exact part for your year and engine with a retailer's fitment lookup or your VIN before ordering - these applications split by engine and build date.
