P1110 – Nissan – Intake Valve Timing Control Bank 1
The OBDII trouble code of P1110 is typically associated with Nissan or Infiniti vehicles. This check engine code refers to an issue with your Intake Valve Timing Control unit. The IVT valve utilizes oil passages to control the variable ignition timing on the intake side of your engine. If your oil passages become clogged or having poor oil pressure can cause this trouble code to trigger and show a check engine light.
This valve controls your engine oil to increase or decrease the ignition timing on the intake side of your engine. This helps your Nissan with low speed acceleration and increased combustion chamber scavenging, which increases fuel efficiency.
This control valve unit can also be known as the IVT valve or the VTC valve. Failure of this component will trigger your Nissan trouble code. When your VTC valve begins to fail or go bad you can use a digital multimeter to check the function of your valve and make sure it’s working. Replacing your intake valve controller can restore your Nissan engine and clear your OBDII trouble code of P1110.
