![]() The similar steps to cleaning, testing and replacing the VTC solenoid on your VQ35 applies to FX35, 350Z, Maximas and many other car and truck applications. If you have an existing P1110 OBDII check engine code, you will need to replace and test this unit before clearing your PCM memory or DTC codes. It’s connected by a two pin weatherproof green connector and is secured by 10mm bolts. The VQ35DE variable timing control solenoids are located in front of the engine and mounted to the side of the cylinder head. The PCM relays real time pulse duty cycles to this variable timing control solenoid, which in turn adjusts the intake valve timing to increase low speed and midrange horsepower and torque. Meaning the ECU will adjust how far advanced or retarded the intake cam will adjust itself to provide superior mid range and low end torque and performance. The Nissan / Infiniti Powertrain Control Module has the ability to use the variable timing control solenoid to change the camshaft phases as driving needs dictate. I’m going to be showing you how to locate, test and remove the variable timing control solenoid in your VQ35 on a 2005 Infiniti G35 AWD, which will resolve the P1110 or related codes. ![]() Many times this problem with the VTC solenoids can lead to knocking noises and poor fuel economy. This is the brother of OBDII check engine code P1135 for the driver side or left hand side VTC module, and can also be accompanied by P0011 for Infiniti models. P0075 and P0081 are both check engine codes that have to do with the variable timing control solenoids in the VQ35DE. Troubleshooting the P0075 Nissan 350Z trouble code So if your Nissan 350Z check engine light is on, and you’ve already confirmed this trouble code using an OBDII scan tool, we can begin. The VQ35 VTC module in your Nissan is the Variable Timing Control valve that dictates valvetrain in your 3.5 liter V6. If you have a P1110 Nissan trouble code, this engine error is often found hand in hand with OBDII P0075. The specific P0075 Nissan 350Z trouble code is related to the VTC module. Today I’ll be showing you how to fix P0075 Nissan 350Z trouble code problems and clear your check engine light. However, that doesn’t mean that Nissan check engine light issues do not arise from time to time. Check the What This Fits tab for more fitment details.Nissan’s 3.5-liter VQ engine found in the late model platforms is remarkable reliable and stout. Shop genuine INFINITI ?Valve Timing Solenoids online and head to a trusted service center for installation. Getting regular oil changes is a great way to help avoid this issue entirely. Oil can clog the passageway from the solenoid to other engine components and prevent it from working correctly. One of the most common reasons for Engine Variable Valve Timing (Vvt) Solenoid problems is dirty engine oil. You may need a new INFINITI timing solenoid if your engine starts rough idling, gas mileage gets noticeably worse, or your check engine light illuminates. How can you tell when it's time to replace the Engine Variable Valve Timing (Vvt) Solenoid? Watch for these potential symptoms because in the worst case, a broken or worn Engine Variable Valve Timing (Vvt) Solenoid can lead to engine failure. When the INFINITI Engine Variable Valve Timing (Vvt) Solenoid functions like it should, it helps support engine performance and fuel efficiency. It takes note of the engine load and speed and regulates the oil flow accordingly. You'll find the Engine Variable Valve Timing (Vvt) Solenoid inside the timing system. Replace early to help avoid engine damage. ![]()
