How does the variable gear system work on a Nissan VVT?
The system is really quite simple. There is a variable gear or sprocket mounted on the intake camshaft that adjusts the camshaft timing based on oil flow and direction. It’s controlled by the ECU by way of the two-wire valve timing oil control solenoid that’s mounted on the valve cover.
What makes a Nissan VVT a good diagnostic?
Due to the ability of Nissan’s variable valve timing system to provide increased engine performance, Bob Dowie offers his diagnostic, electronic and mechanical expertise for how import vehicle specialists can most effectively perform engine service.
How does the ECU work on a Nissan VVT?
It’s controlled by the ECU by way of the two-wire valve timing oil control solenoid that’s mounted on the valve cover. The ECU looks at coolant temp, RPM, injector pulse and cam position sensor to make its decisions on where the cam should be, and if the system is working as expected.
When did Nissan start using variable valve timing?
There is nothing new about the technology; Nissan was one of the first manufacturers to introduce variable valve timing in the late 1980s on the V6 engine in the 350Z, and now it’s used throughout its line.
How much does it cost to replace the solenoid on a Nissan Juke?
The average cost for a Nissan JUKE variable valve timing control solenoid replacement is between $350 and $457. Labor costs are estimated between $35 and $45 while parts are priced between $315 and $412. Estimate does not include taxes and fees.
Where is the variable valve timing solenoid located?
Step 3: Locating the variable valve timing solenoid. The variable valve timing solenoid is located at the front of the engine, typically near the front of the valve cover. Try looking at the new solenoid to match the shape and help you find it. The connector is the exposed end of the variable valve timing solenoid.
Which is the most important variable valve control solenoid?
Variable valve timing systems have several components required to operate, perhaps the timing control solenoid is the most important. The variable valve timing control solenoid is responsible for engaging and disengaging simple variable valve timing systems, and will constantly adjust more intricate systems.
How do you remove a solenoid on a car?
Start by removing the mounting bolts and be careful not to drop them in any crevices or openings in the engine compartment. Step 7: Disconnect solenoid. Remove the connector on the solenoid. Most connectors are removed by applying pressure to the tab to release the lock on the connector itself.
