What causes a transmission solenoid to be intermittent?
When a transmission solenoid is working intermittent, in most cases, the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body.
What are the possible causes of Nissan p0744?
P0744 NISSAN Possible Causes 1 Faulty torque converter clutch solenoid valve 2 Torque converter clutch solenoid valve harness is open or shorted 3 Torque converter clutch solenoid valve circuit poor electrical connection 4 Low transmission fluid level 5 Dirty transmission fluid
What happens when torque converter solenoid valve is activated?
When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter. Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
What are the symptoms of a transmission solenoid problem?
The most common symptom of a damaged transmission shift control or wirings is a warning light on your dashboard. This is often a check engine light or a transmission warning light. If you see a warning light on your dashboard, read the trouble codes with an OBD2 scanner and start your troubleshooting there. How to Diagnose a Shift Solenoid Problem?
Can a check engine light cause variable timing solenoid to fail?
This is the thing about modern cars that the ECU or engine control unit starts to warn you as soon as it finds some problem in the engine. It can, in fact, practically monitor all the individual parts of the car. So, in case of an impending variable valve timing solenoid failure, it is due to war you with check engine light.
How does the solenoid work in a car?
As you drive, the car’s computer determines which gear is optimal for your speed. The transmission control module (TCM) — the brains of the transmission — will send power to one of the shift solenoids in order to shift gears. Inside the solenoid, there’s a plunger surrounded by a magnetic coil.
What happens if your VVT solenoid goes out of order?
In case this VVT solenoid goes out of order, improper lubrication can cause a lot of damage and disruption to the gear and the timing chain. If playback doesn’t begin shortly, try restarting your device.
