Why Is My Nissan Altima Stalling?

The fuel system, the air intake system, or the ignition system are the three most frequent causes of an engine stalling in a Nissan Altima.

Common causes of this include:

Transmission malfunction: The torque converter, which replaces the manual clutch in a car with an automatic transmission, is in charge of transferring power. The converter won’t function properly if the torque converter is damaged or if the transmission fluid level is low; as a result, the vehicle won’t be able to sustain power at low speeds, which results in the engine cutting out. This problem can also be brought on by a broken torque converter solenoid or TCS.

The fuel pump is in charge of moving fuel from the tank to the engine regardless of low fuel pressure, filthy or damaged fuel injectors, or a faulty fuel pump. Low fuel pressure from a damaged fuel pump can lead to an uneven stream of fuel being delivered to the engine. This doesn’t matter as much at high speeds, but at low speeds, even a little interruption in the fuel delivery might cause the engine to stall. A precise amount of fuel is sprayed out by the fuel injectors, and at the right moment, it is ignited by the spark plugs. Over time, injectors can get clogged or unclean, which causes irregular spray or no spray at all.

Bad oxygen sensor or mass flow sensor: The oxygen sensors and mass flow sensor let the vehicle adjust the air-to-fuel ratio by detecting how much oxygen is entering the fuel stream. Your vehicle won’t run as efficiently if the oxygen level is too high or too low. The car will continue to run at driving speeds, just like with low fuel pressure, but this insufficient power won’t be able to fuel the vehicle when it slows down.

Wires that are loose or rusted in the wiring harness: An ignition that fires inconsistently will cause an easily stalled engine. The vehicle can quickly lose voltage and won’t have the power it needs to remain running when you slow down if the wires are not in steady, dependable, and consistent contact with the ignition circuit.

Idle air control actuator malfunction: During idling, the engine’s RPMs are controlled by the idle air control actuator. The electronic control unit (ECU) sends information to this actuator, letting it know what RPM to keep the engine at for a secure and smooth idle. When the actuator is broken, the engine is not sent a signal for the idle speed and shuts off.

EGR valve obstruction or restriction: Depending on whether the EGR valve is jammed open or closed, a clogged, unclean, or damaged EGR valve might cause your automobile to stall, idle incorrectly, or sputter.

Crankshaft or Camshaft Position Sensor Failure

The vehicle may not start or the engine may stall while the automobile is driving as a result of a malfunctioning crankshaft or camshaft position sensor, which can be hazardous. Additionally, customers have mentioned jerky riding once the engine has started.

You can notice frequent stalling, decreased gas mileage, decreased engine power, or even worse, the car not starting at all, if one or both of these sensors are failing. You should have your sensors inspected by a professional if you suspect that they are failing.

Even if just one of the sensors may be malfunctioning, it is advisable to get them both replaced if you find that it is only one of them. Consumers have been complaining about it frequently over the years, which prompted Nissan to issue a recall. You must contact a Nissan dealership to find out if your Nissan Altima is covered by the recall because it is VIN-specific.

The mostly impacted 2.5L 4 cylinder and 3.5L V6 engines span 24 model years, starting in 1993 and continuing through 2017. As previously said, having faulty crankshaft or camshaft position sensors is a serious safety concern and can be dangerous, so if you’re buying a pre-owned Nissan Altima, you should have these two sensors checked out. The cost of repairs might range from $167 and $215.

The engine of the Altima stalls.

The Nissan Altima’s engine stalling was by far the cause of the majority of complaints. Because the automobile stalls while moving, bringing drivers to a sudden stop in the middle of traffic, it can be a very dangerous problem. While the car was in parking, other drivers also encountered the stall.

Failure of the crankshaft position sensor or the camshaft position sensor is a common cause of this issue. Because the issue recurs, it might be difficult to identify the cause. There was a recall due to this problem for the 2.5-liter engine Nissan Altima cars from 2002, 2005, and 2006. As necessary, the recall replaced the sensors.

My 2013 Nissan Altima is stalling; why?

Simply said, if the engine is unable to handle the load, the car will stall when it is put into gear. Engine control issues are one of the potential causes of that. The manifold absolute pressure (MAP) sensor, idle control valve, and throttle position sensor can all be tested by a mechanic. The level of vacuum in the intake manifold is proportional to the signal the MAP sensor produces when it detects engine load. This data is used by the ECU to modify the fuel enrichment and ignition timing in accordance with the required level of power. As the throttle opens widely and the engine draws in more air during strong acceleration, the intake vacuum decreases, which increases the amount of fuel needed to maintain a constant air/fuel ratio. The fuel mixture is changed to be somewhat richer than usual by the computer when it receives a signal from the MAP sensor indicating a heavy load in order to increase engine output. The ignition timing will then be slightly delayed (backed off) by the computer to avoid detonation (spark knock), which can harm the engine and reduce performance. This procedure may help to explain why the engine dies when you put the car in gear and place a load on the motor, IF the MAP sensor is defective. Defects with the torque converter of an automatic transmission and/or the torque converter lock up solenoid are other potential causes of stalling. Another option is that there is an internal hydraulic leak in the transmission seals, which would lock up the transmission and cause the engine to stall by pushing on the reverse and forward gears simultaneously. To determine whether such a leak is brought on by a leaky seal or a leaking forward or reverse solenoid/valve, pressure testing using external gauges can be utilized.

When I accelerate, why does my Nissan Altima stall?

For a combustion engine (gas or diesel) to operate well, the fuel and air must be precisely balanced. If there is any deviation from this combination, the engine may run too lean (not enough air) or too rich (not enough fuel). A fuel/air mixture that is excessively lean is most likely the cause of an engine’s hesitation when accelerating. When an engine is operating inefficiently, it will start to exhibit symptoms like hesitancy, which will only become worse over time. Have your vehicle checked out right away if you detect any signs, such as hesitation.

What is the Nissan Altima’s most typical issue?

Engine Stagnation One of the most frequent complaints from Nissan Altima owners is this problem. Many incidents have occurred while they were travelling on the road, while other people have reported the engine stopping while the automobile was at a stop.
