What causes sudden idling in a Teana car?

[MacGideon]

Reasons for sudden idling in a Teana car: Insufficient fuel pump pressure: When the fuel pump pressure is inadequate, the fuel injection volume is insufficient, preventing the engine speed from increasing. Exhaust system issues: Poor exhaust flow reduces the efficiency of the engine's intake and exhaust systems, hindering the increase in engine speed. Definition of idling: Idling refers to the operating state of a machine or instrument without any load, which can cause the driving wheels of a locomotive or car to spin on the tracks or road surface without moving forward. Causes of idling: When the tangential force on the circumference of the locomotive's driving wheels exceeds the adhesion between the wheels and the tracks, the adhesion is compromised. This results in relative sliding between the wheels and the rails at the contact point. Under the driving torque, the wheels rotate rapidly around the axle, leading to idling.

I've been driving my Teana for over a decade and have encountered several instances of engine revving without acceleration. When the engine RPM suddenly spikes but the car doesn't move, it's usually the transmission acting up. The most common issues with CVT transmissions are steel belt slippage or insufficient oil pressure, especially in older vehicles that haven't had their transmission fluid changed after 70,000-80,000 kilometers. I once experienced a stuck transmission valve body that caused signal transmission chaos. Another dangerous situation is when the drive axle shaft breaks, leading to sudden loss of power. My advice? If you experience engine revving without movement, don't keep driving - pull over immediately and call for assistance. Transmission repairs can be painfully expensive. Regular transmission fluid changes can prevent such problems - that's my hard-earned experience.

With 20 years of car repair experience, Altima owners often complain about idle issues. Focus on the CVT transmission system: First, use a diagnostic tool to read fault codes, commonly P0776 pressure control solenoid valve fault code. Then check if the oil pressure is below the standard value of 2MPa, as insufficient oil pressure can cause belt slippage. Next, inspect the condition of the transmission fluid; a burnt smell indicates overheating and wear. On the electronic side, check if the TCU module has water damage or short circuits. For the mechanical part, inspect whether the torque converter lock-up clutch has failed. A friendly reminder: prolonged low-speed climbing or aggressive driving can easily trigger these issues. Timely replacement of NS-3 specialized fluid is crucial.

My Teana just had a sudden revving issue last week - scared me to death! Stepped on the gas but only heard the engine roar while the car wouldn't move. My friend suggested checking the transmission dipstick, and sure enough, the fluid was black as coffee grounds. The mechanic said CVT transmissions are prone to this - especially need caution about steel belt wear after 80,000 km. Another time it revved after heavy rain - turned out the transmission control module got waterlogged and short-circuited. Learned my lesson now - regular transmission maintenance and avoiding sudden acceleration. Never force-drive with this issue - my friend's car had minor damage turn catastrophic, ending up spending over 10k to replace the entire transmission assembly.
