Nissan Altima Troubleshooting
Is your Nissan Altima giving you starting problems? Is the remote not working? Without knowing the cause of the problems you face, you cannot be sure of having the right repairs done. Trial and error methods waste time and money and can exacerbate the problem. The insights of verified mechanical Experts will guide you to the causes and help you find the right solutions.
Here are some questions that Experts have answered.
Is a slight oil leak from behind the power steering pump on a 2007 Nissan Altima 2.5S a sign of a serious problem?
Case Details: The vehicle runs perfectly with no noise or vibration.
If the leak is a small one, it may not indicate a serious issue, especially if the engine is running so well. A leak from behind the power steering pump could be from the oil sending unit or the oil cooler. If this is the case, replacing the defective part should fix the problem. Many large auto parts stores will not charge for checking the leak and will also give a free repair estimate.
Is a fuel supply/pressure issue the reason why a 2005 Nissan Altima will only start if starting fluid is used?
If the vehicle starts with starting fluid, it means that there is a fuel issue and the spark is okay. The most common cause of fuel supply issue is a failing fuel pump. Turn on the ignition and listen carefully to hear the sound of the pump running. It should last for a few seconds. If no sound is heard, the pump may not be getting power or it may have failed. Check the relays and connections to the pump and fix any faults that are found. If there are no problems, look for the fuel line that runs by the brake booster. It will have a plastic cover. Pull the cover off and then push the ends of the clip in. Then pull it apart. Have a helper crank the engine while watching to see if fuel flows from the line. If it does not, or only a few drops emerge, the pump is bad and will need to be replaced.
If there is power to all the window switches on a 1994 Nissan Altima but three of them do not work, what could be wrong?
Check the wiring from the switches of the nonfunctional windows to the motors. If any damaged wires or loose or corroded connections are found, replace them. If there are not problems, then the motors have failed. It is unusual for three window motors to fail at the same time, but if there is power to the motors, there can be no other reason. The motors will have to be replaced.
Why is the key fob of a 2012 Nissan Altima not working and the security indicator light remaining on?
Case Details: The battery, which is new, appears to be dead, there is no electrical power at all.
This could be a case of parasitic draw which happens when a circuit draws excess power with the ignition off. To check for this connect a voltmeter to the battery positive cable. Remove the fuses one at a time. When the voltage drops, that is the circuit that is faulty and will have to be checked. The other possible cause is what is known as a “Double Tap.” This is when the Start button is accidently pressed more than once when turning off the vehicle. When this happens, the driver often exits the vehicle without seeing that the ignition is in the ON position. This will drain the battery in a few hours. If this is what happened, charging the battery should fix the problem.
What does a P0021 fault code mean on a 2007 Nissan Altima 3.5SE V6?
Case Details: The check Engine light is on, the vehicle is sluggish and shakes when idling.
This code is for a faulty bank two cam position sensor which is located on the back of the cylinder head. This will account for the problems being faced. Replacing the sensor should fix the problem. Low engine oil levels could contribute to the issue, so check and top up the oil if required.
Why does a 2003 Nissan Altima with automatic transmission hesitate before shifting into 1st gear when the engine is warm?
Case Details: The shifting is fine with a cold engine. A scan showed a speed sensor code.
The speed sensor code can be set if the computer sees that the transmission is not at the correct speed for the selected gear. A faulty valve body is a common reason for this to happen. A failing speed sensor will normally affect all the gears, not just 1st. Flush the transmission to remove any debris that may be stuck in the valve body. If this does not help the valve body should be examined and replaced. Only if the valve body is found to be okay should the speed sensor be tested.
Why is a 2010 Nissan Altima with push button start and a new battery not cranking?
Case Details: The brake lights are not working and the foot pedal sign is illuminated on the dash.
If the brake lights are not working and the foot pedal warning is on, the brake switch has failed. The brake switch is a major input for push button start vehicles and without this, the engine will not turn over. Replacing the switch should fix the starting issue and cause the brake lights to start working.
