P1136: Intake Valve Timing Control Solenoid Valve Circuit, Bank 2
3 vehicles · 1 makes
Most Reported On
P1136 is an OBD-II diagnostic trouble code meaning “Intake Valve Timing Control Solenoid Valve Circuit, Bank 2.” A Nissan/Infiniti manufacturer-specific code. The ECM pulses the intake valve timing (VVT) control solenoid with an on/off duty signal to route oil that advances or retards intake cam timing, and this code sets when it sees an abnormal electrical condition in that solenoid circuit on Bank 2. Symptoms are usually a check engine light with mild rough idle, reduced low-end power, or slightly worse fuel economy. On these engines the fault is very often oil-related rather than a bad part, so change the oil and filter (and try cleaning the solenoid) before condemning it. Other makes use P1136 differently - VW/Audi assign it to a Bank 1 lean additive-mixture fuel trim fault. This code is most commonly reported on 2014-2025 Audi SQ5, 2009-2025 Audi Q5, and 2009-2021 Audi A4.
