P1692 OCV for VVT-L Open Malfunction

• OBD2 Code: P1692
• Description: OCV for VVT-L Open Malfunction
• Definition: This code indicates that there is an open circuit condition in the Oil Control Valve (OCV) for the Variable Valve Timing with Lift (VVT-L) system. The OCV is responsible for controlling the oil flow to the camshaft timing gear, and an open circuit can prevent proper operation of the VVT-L system.

• Faulty Oil Control Valve (OCV)
• Wiring or connector issues in the OCV circuit
• Low engine oil level or dirty engine oil
• Engine mechanical problems affecting the OCV operation

 

Common Misdiagnosis

OBD2 Code: P1692

Description: OCV for VVTl Open Malfunction

Common Misdiagnosis: Faulty oil control valve (OCV) is often misdiagnosed as a faulty variable valve timing (VVT) solenoid or camshaft position sensor issue.

 

Common Diagnostic Steps

OBD2 Code: P1692

Description: OCV for VVTl Open Malfunction

• Check the oil level and quality. Low or dirty oil can affect the operation of the Variable Valve Timing (VVT) system.
• Inspect the Oil Control Valve (OCV) for any signs of damage, wear, or blockage.
• Test the electrical connector and wiring to the OCV for continuity and proper connection.
• Use a multimeter to check if there is power and ground at the OCV connector when commanded by the engine control module (ECM).
• Perform an actuator test using a scan tool to ensure that the OCV is functioning correctly when activated by the ECM.
• If applicable, inspect and clean or replace any clogged VVT filters or screens in the oil passages.
• If all else fails, consider replacing the OCV as it may be faulty.
