What kind of transmission does a 2012 Nissan Quest have?
continuously variable transmission
The 2012 Nissan Quest is powered by a 260-horsepower V6 engine. The transmission is a continuously variable transmission (CVT), which reviewers aren’t overly fond of, in part because it lacks a system to keep the Quest from rolling backward when starting on a hill.
What problems can low transmission fluid cause?
When your transmission fluid is low, your car won’t generate as much hydraulic pressure, leading to what’s known as gear slippage. Gear slippage commonly manifests as a failure to accelerate properly. When your transmission fluid is low, you may notice your vehicle reaching high RPMs while moving sluggishly.
What happens if you have transmission code p0868?
Ideally, vehicles on which code P0868 is present should not be driven, since there is a possibility that the transmission could fail, or enter a limp mode unexpectedly. This could cause crashes if the vehicle should suddenly lose power while driving in traffic. How difficult is it to repair code P0868 ?
What are the error codes for CVT transmission?
Codes: P1778, P0746 and P0868: Hi All, My Car Has a CVT XTRONIC My car has a CVT XTRONIC transmission. A quick summary of my question: my car is diagnosed with these error codes;P0746, P1778 and P0868. Do I need to replace the transmission? Or a transmission specialist would be able to fix the issues?
What happens when transmission fluid pressure is too low?
Thus, when the pressure falls below a limit set by the manufacturer, the PCM or TCM (Transmission Control Module) is no longer able to initiate gearshifts, since a set minimum pressure is required to initiate a gearshift on the one hand, and to maintain the gear selection on the other hand.
What does 178 mean on a CVT transmission?
Find a transmission shop that works on them as a lot of guys are not in tune with them yet. Manufacturers are slow to teach outside mechanics about them. The two codes are listed in picture for causes, but 178 is the step motor which means it works okay electrically, but mechanically there is something wrong.
What does the code p0868 mean on a Nissan?
P0868 NISSAN Meaning The Pressure Control Solenoid Valve ‘B’ (secondary pressure solenoid valve) regulates the secondary pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM).
What should line pressure be in DTC p0867?
If the difference between actual line pressure and desired line pressure is 10 psi (.7 kg/cm2 ) or greater, DTC P0867 will set. Transmission system will default to open loop line pressure control resulting in a fixed solenoid duty cycle.
What is the diagnostic code for transmission fluid pressure low?
P0868 is a diagnostic trouble code (DTC) for “Transmission Fluid Pressure Low”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What causes a transmission fluid temperature sensor to set to p0868?
Some common causes of code P0868 could include the following- Damaged, burnt, shorted, disconnected, or corroded wiring and/or connectors In some cases, a defective transmission fluid temperature sensor might contribute to the setting of code P0868, although this is rare
